    • Tiffani Morrell Sloan

      Rainbow Cake in Jar 1 box white cake mix made according to package instructions Neon food coloring in pink, yellow, green, turquoise, and purple 3 one-pint canning jars 1 can vanilla frosting Rainbow sprinkles Preheat oven to 350 degrees. Thoroughly wash and dry the inside of each canning jar. Spray the inside of each jar thoroughly with nonstick cooking spray. Set aside. Scoop about 1/2 cups of cake batter into five small bowls. It doesn’t have to be perfect, don’t panic if you get a little more of less of one color than another. Tint each bowl of cake batter with the food coloring until very vibrant. Spoon about 3 tablespoons of the purple batter into the bottom of each jar. Spoon equal amounts of turquoise batter, then green, yellow, and pink. Place the jars in a shallow baking dish, add about 1/4″ in water in the baking dish. Place the baking dish in the oven and bake for 30-35 minutes. Remove jars and allow to cool completely before scooping a small portion from the top of your cake and adding a hefty dollop of vanilla buttercream to the top. Sprinkle & serve, or cover with a lid and store in the fridge or pop into the mail & surprise someone you love! POST EDIT: Several commenters have indicated that the cake is not cooking all the way through in the 30-35 minutes indicated in the recipe. This was enough time for our cake, but I’m cooking at high altitudes, and my oven tends to bake hot. So, I’d recommend baking the cake for 40 minutes, then return it to the oven if it still doesn’t spring back to the touch when you check to see if it’s finished. As for the cake puffing up and out of it’s bottle, ours did that a bit, as well. Easy fix. We just scooped a bit of the cake out to make room for the frosting and wiped the outside of our jars clean. Several people have indicated that the wide-mouthed mason jars work a little better for this purpose. I’ve not yet baked with wide-mouthed. What you see above is what was baked in my kitchen according to the recipe instructions, and what came out of the oven when it was all. Of course, if you’re feeling wildly impatient, you can also zap the cake in the microwave for 2 minutes. It’s going to bubble up, for sure, but you can scoop the top part of that cake out, frost it, and no one will ever be the wiser. Good luck, everyone! This is such a fun cake. My kids went nuts over it, and I hope it works as beautifully for you as it did for us!

A mini cake for everyone! sheila commented on Apr 08 11 at 11:46 pm I have made other types of cake in a jar. Some can keep for months if properly stored. This cake would be really cool if it was done in the wide mouth quart canning jars, because then you can pop it out and the slices would be so cool. Thanks for a great idea.. Cammie commented on Apr 11 11 at 8:44 am What a fun idea!! Love it!! Thank you so much for sharing this! Michelle commented on Apr 11 11 at 10:32 am I LOVE this! Sue commented on Apr 11 11 at 10:52 am this is the perfect thing to send to my brother for his birthday this week, he’ll love it! Katie commented on Apr 11 11 at 11:09 am That looks so pretty, I love how you can see the colours right away. And if you don’t finish it you can put a lid on the jar and take it to go! Awesome. Bright Shadows commented on Apr 11 11 at 1:01 pm Love it will definetly try this Jael Cain commented on Apr 11 11 at 2:01 pm Okay, so did anyone who commented actually try this… do tell how it worked out for you….. Windi commented on Apr 11 11 at 10:15 pm WONDERFUL idea !! Will definitely try this sooon! Recently posted a great vanilly cupcake recipe which guarantees nice domes :-) Stop by :-) Nina from commented on Apr 12 11 at 7:50 am i did the recipe and for some reason when i let the cake cool, they shrunk in the jars! anyone know why? Eddy commented on Apr 13 11 at 2:33 am Did anyone care to think that the jars would break from the heat in the oven? Elena commented on Apr 13 11 at 11:17 am OMG! LOVE these. (where I work) has been doing a bunch of rainbow stuff lately. We have your post featured on our Facebook page! Check it out!!/Tablespoon These are the recipe…… Erin commented on Apr 13 11 at 3:00 pm At ELENA: Exactly, thats what I was thinking. Because today I kept a glass of joghurt instead of throwing it away and I wanted to try the cake in a jar as well. I dont know whether I can use normal, ordinary glasses/jars from the supermarket that had joghurt or other stuff in them… Does anybody know?? Just baked sugar cookies and coka cola cupcakes…they are soooo delicious!! Will post the recipes on in a couple days. Greetings everyone Ninah Ninah from commented on Apr 13 11 at 4:40 pm Love, love love!!!!! My kids will go nuts over these! :) Kate commented on Apr 13 11 at 5:47 pm @ Elena the jars should be able to withstand the heat in the oven as they shouldve been annealed in a lehr previous to them going on sale, also the placing them in a tin of water helps Lauren commented on Apr 14 11 at 7:21 am Awesomeness!!! Kim commented on Apr 14 11 at 10:35 am This is probably the most adorable thing I’ve ever seen. My friend and I have started this tradition where we send treats back and forth in the mail (she’s in Pensacola and I’m in Orlando) just as a Thinking of You! type thing. In the last box I got she had put mini cupcakes inside mini mason jars and I’ve been stumped with what to send back because I’m worried about the Florida heat. But this is perfect (sans icing)! I’m super excited to hear about her reaction when she opens the box and finds these beauties. Thanks for the great idea! <3 Katie commented on Apr 14 11 at 1:02 pm You don’t get colors as vibrant as those from food coloring? Are you sure your didn’t use food color gel? Please clarify. J commented on Apr 14 11 at 9:11 pm That looks revolting. ELBSeattle commented on Apr 15 11 at 12:52 am Oh my word these look amazing! What an cool idea Nadia commented on Apr 15 11 at 10:45 am Oh my word these look amazing! What an cool idea Nadia commented on Apr 15 11 at 10:45 am These are awesome! I already have so many ideas for holidays….green & red alternating color cake for xmas… & orange for halloween..etc. @ J…. it’s NEON food coloring which is more vibrant than just regular ol’ food coloring. :) Cookie Monster commented on Apr 15 11 at 9:18 pm You’re so clever! I know some people I just have to send these to! Madoline Madigan commented on Apr 15 11 at 10:01 pm – sunshine in a jar!! crunicorn commented on Apr 16 11 at 1:30 pm These are AMAZING! I’m always on the lookout for stuff that our kids club can make and this is now top of my list! Thank you so much for sharing! And I definately think baby food jars is the way to go for kids! Bee commented on Apr 16 11 at 4:27 pm SUPER cute idea. My 11 year old daughter and I used this as our “Girl’s Night In” recipe and had SO much fun! We just made these tonight and ran into a few problems. The cakes were “runny” in the middle…not completely cooked through and once they cooled they shrunk terribly as someone else had mentioned. For filling the jars, we found that using an ice cream scoop cut down on getting the sides “messy” and spinning the jars a few times helped to level the layers out nicely. L commented on Apr 17 11 at 2:20 am I ran into the same problems. The first batch came out severely undercooked and then shrank a lot. The next batch I bumped the heat up about 10 degrees, and baked them for 40 minutes, and they STILL came out undercooked and while they were baking the cake batter ERUPTED out of the mason jars. I am so disappointed :( Any tips so my NEXT attempt doesn’t fail? Barbara commented on Apr 17 11 at 3:24 pm @Bee and @Elena I would stick with canning jars for anything baked, as the glass is tempered to withstand higher temperatures than normal. Food storage jars off the grocery store shelf may shatter in your oven. That said, I’ve done pies in the 4 oz wide mouth jars, and they were adorable- a bigger hit with the adults than with the kids. I think it’s the portion control factor that made the small jars so attractive. Lauren commented on Apr 17 11 at 9:02 pm I tried making one of these awhile ago and it shrank drastically when I placed it on my jar, what am I doing wrong? vedette commented on Apr 19 11 at 11:27 am I recently discovered mason jars and am obsessed! I can’t wait to try this out it looks yummy, I’m now always looking up new ways to use them lol Jane commented on Apr 19 11 at 2:46 pm I just made these and am not sure how to post my pics. I used regular jars off the grocery store shelf. If following the instructions of putting water in the baking dish you should be fine with any type of glass jar. Mine came out 70′s looking dark on the outside but as soon as you take a piece off the top the inside is really cool. I made them because I’m headed to the beach for 5 days and while there have a niece celebrating her 9th so this is absolutely perfect. Put a lid on and they travel. I know I didn’t layer the mix correctly as it didn’t look close to the picture but it is ok. The inside is bright and swirly with colors. I’ll try to post pics and thanks so much to whoever was the original poster. sam commented on Apr 20 11 at 12:50 am We at do something close. It is our “Stars N Stripes” cake. We swirl the batter. Our Facebook page has pictures of it. This is a really cute recipe. Thanks for sharing!! CK Bakery Shop commented on Apr 20 11 at 12:36 pm Oh my – I just HAVE to make these for my kids birthday parties this year. How fun!! Denine M. Anderson-Regan commented on Apr 21 11 at 4:35 pm Oh, dear Lord these are SO FREAKIN ADORABLE! I love to bake and look for fun and unique recipes! I will DEFINITELY bookmark this page to keep for whenever I want to make something fun and different for family and friends! Beth commented on Apr 21 11 at 8:33 pm It´s pathetic ANGRY GOD commented on Apr 22 11 at 2:43 pm Mine are not quite like the pictures :( They are darker and they shrunk… Any help? These were the trial runs so I need to perfect them for end of year teacher gifts. Thanks! Candi commented on Apr 23 11 at 9:39 am The colours of my cake definitely did not turn out like the picture. They came out a little brown, but that’s to be expected. Z commented on Apr 23 11 at 8:29 pm isnt there a recipe for the cake? I cant get cake mixes like that here in germany, and I would rather make it myself, would ordinary sponge cake work? Awsome idea, cant wait to try it out. lisa commented on Apr 24 11 at 4:53 pm I made these last night but they didn’t turn out as pretty, they browned all over the sides. Could it have been because i used vanilla cake mix instead of white? I’ll be trying again tonight because it’s such a wonderful idea. haylea commented on Apr 24 11 at 10:34 pm Super cute idea, and I attempted to make a few tonight, BUT…how do you get them to come out so “pretty”? Like others have stated, the sides browned a bit and the colors are not as crisp as the picture…the colors are definitely vibrant once cut into. I sprayed the jars before pouring the batter, and the jars were placed in a water-bath while in the oven. Any suggestions? Would really like to try them again, but with better results. :) Rita commented on Apr 25 11 at 9:59 pm Just tried my first batch…..the colors ran horribly when I tried to “layer” them. The cake mix was way too runny. I added corn starch and flour to each color, and the consistency was MUCH better for layering. I would def recommend doing this! Sarah commented on Apr 26 11 at 2:54 pm I love love love cake! What a cute idea. I’ll have to give it a shot! jen @ onecurlyfry commented on Apr 26 11 at 3:31 pm Who on earth would like to eat such thing. Looks radioactive! Kris commented on Apr 27 11 at 2:01 pm I want to send one in the mail to my friend across the country, but I’m worried that it might mold :/ how long do they last and still taste good? It would need to survive over 6 days in the post. Leah commented on Apr 28 11 at 8:35 am AWESOME! Thank you for the great spring/summer idea ;) jennibell commented on May 01 11 at 11:17 pm I cannot get over these. They are sooooo beautiful. I just wanna stare at them. Meli commented on May 03 11 at 5:31 pm I made these as instructed. They baked up really thoroughly and I thought I was in the clear. However, once they had cooled the condensation from the cooling process moistened some of the batter at the bottom of the jar quite drastically, to the point where I can’t give these as gifts in the morning. I know they were cooked through because while one was still warm I couldn’t help myself and had to dig in! :) It was cooked all the way to the bottom. Also, they shrank quite dramatically. After an hour I thought they were cool and they had shrunk slightly; however, by the time I went back to frost them – several hours later – they had shrunk more. I used the gel food coloring to keep the colors vibrant. I found that even though I assembled the batter in a layered fashion the cakes ended up all mixed up – which was fine; it was cute, too. Just not as pictured. If I were doing this over again I’d buy the wide-mouth jars. When they came out of the oven I’d attempt to pop them out of the jars to cool. Once they had cooled I’d put them back in the jars. I think this might help with the batter problems I seemed to have, and possibly the shrinking issues. Heidi commented on May 04 11 at 1:10 am I also would like to know how long these would stay fresh if it was sent in the mail? Will it be ok 6 days later in the mail as Leah above had questioned? Should it be first put in the refrigerator before mailing or just get it to room temp after baking and then put the cover on and then ship out? Please help. I love this idea and would love to create and send this out for all the dad’s I know for father’s day. Peechee commented on May 06 11 at 9:35 am Up to three days, Peechee. You’ll want to expedite them in the mail to ensure the utmost freshness. Brooke McLay commented on May 06 11 at 9:38 am I tried this tonight for my friend’s birthday. My local grocer doesn’t carry neon food dye, so I anticipated my colors to be a bit darker than pictured here. I used a larger jar than suggested, so I cooked it a few minutes longer. The outsides did indeed brown a little, so the colors appear even darker. But when I scooped the top off to make room for the icing, the inside was surprisingly bright! All in all I am very satisfied with this idea. My gratitude to Brooke Mclay for sharing this grand idea! CatyDid commented on May 07 11 at 3:59 am OMGoodness….the jars are in the oven and they are looking AWESOME! I live in southern LA, below sea level (lol)…so I definitely had to go with the 40 minutes! My son is giving this to his teacher with a note attached saying “You take the cake!”…thanks so much for this idea! Andrea commented on May 10 11 at 2:31 pm These are quite cool and fun to make, did them for a friends birthday. Thanks for the idea. However, they turn out much much darker then expected, and not nearly as neatly layered as the ones in the picture. newbie commented on May 11 11 at 12:41 am Michelle commented on May 11 11 at 4:01 pm Made banana bread in a jar. Came out great, a tad dry from fridge storage, best to eat same day. luv ya. Francesca commented on May 11 11 at 8:52 pm These were an amazing idea! Although, I did have a little bit of a problem when putting in the batter. How do you put the batter so the colors so blend so much? Melinda commented on May 11 11 at 11:39 pm Brooke you are the coolest mom ever. I love all your colorful ideas! Laura Flowers Laura Flowers commented on May 12 11 at 3:59 pm These are adorable. So glad that I stumbled onto your sight! Your ideas are precious. Can’t wait to try them! Bettie commented on May 12 11 at 4:15 pm I am thinking about making these for my daughter’s 14th bday party. Can someone please tell me about how many one batch of cake makes?? PJ commented on May 14 11 at 2:05 am this DID NOT work for me at all!): i was so excited. i’ve attempted it about 4 times now and it’s just not working! i am sad! jason commented on May 14 11 at 2:39 pm Mine came out browned too – and HUGE – and the colors mixed together. I’m going to try again, adding the flour and corn starch to make it thicker, then I’m going to cook in the microwave to avoid browning. Or I’ll cook at a slightly lower temp; my oven runs hot. becky commented on May 14 11 at 4:44 pm If you leave the frosting off and put the lids before the cake cools they will seal and will be good for months and can be mailed to our troops over seas. Lynette commented on May 14 11 at 5:04 pm I tried this today with an 8 oz jar. I only made one jar’s worth since I had a cake recipe that made 2 servings of cake (which was the perfect amount for one 8 oz jar). While the colors may not have been as brilliant as the pictures above, they were definitely very vivid. My main problem was with the layering of the colors. I had blue on the bottom, then pink, then purple, then green. When it cooked, the blue and green dominated but once you started eating it, there were swirls of pink and purple on the inside. I think the 8oz jars work perfect for this. I filled them a little less than half way, and the cake rose to about a 1/4 inch from the top. I’ll be making 6 of these on Thursday for a friends birthday, so we’ll see if I can figure the layering thing out better. Lisa Dawn commented on May 14 11 at 10:51 pm Ok so I made these today and for some reason my green on the bottom shows more than the other colors… Idk why but gonna try again next week but gonna layer them different….. I think I am gonna put the batter in to bags and squeeze in several different layers.. Green purple blue pink repeat… Will let ya know….. Heather commented on May 15 11 at 5:52 pm Can You use a baby food jar Tara commented on May 17 11 at 1:46 am I made this today with short and fat 16 oz jars; one box of white cake mix made three jars. I baked each jar separately to make sure they were evenly baked. The first time, the colors were very dark and the bottom of the cake mix did not bake all the way. The second time, the colors were a little better because I added more dye but the cake then boiled over the top making a mess. The third time I used a lot more neon dye and the pink was gorgeous when it came out. I don’t know if it would work for every color, but using more dye made the colors more vivid. However, they still were a little brown and I did not like how they looked. I don’t know what I was doing wrong but my colors definitely did not turn out like the picture. I think from now on I will be making rainbow cupcakes instead. So this was not a total waste! Good idea though, looks so cute if it is done right. Melanie commented on May 17 11 at 4:03 pm I was so excited to do this until I started reading the reviews. Now I’m scared to try it! Maybe I will any how ;) Amber commented on May 18 11 at 7:40 pm sorry you didn’t mention anything about the glass. i once happened to cook something inside a glass recipient in the oven and it wasn’t heat proof so it broke. does it have to be heat proof glass or it worked just fine for you with regular jars? mercedes commented on May 21 11 at 11:14 am i love all the bright colors. i also posted a few similar things at my site : . loving the original idea. great post. שף בבית commented on May 24 11 at 8:41 am i can’t get enough of this!! i just had to share it with my readers too! breanna commented on May 25 11 at 1:57 pm I did a practice set of these today for my daughters tie dye party. I used 6 half pint jars instead of 3 pint jars. They turned out so cute! I had no problems with them at all. I used the neon dye. They erupted over the sides, as to be expected, but cleaned them up and they are adorable! I also swirled the jar around each time I put a new color, to make sure each color shows. Sine they were smaller, Chelsea j. commented on Jun 01 11 at 1:43 pm Oops I meant since they were smaller I baked for 16 mins to start, put them back in for 5, then 3 more, for a total of 24 mins. Seemed to do the trick! Thanks soo much for sharing! Chelsea j. commented on Jun 01 11 at 1:44 pm A little late to the game I see, but my little man and I just finished our first batch of these and they are BEAUTIFUL! So they did brown a little (cake does that, weird!) and I left too much room in the jars, so… extra frosting! They’re not perfect, but since the delighted taste testers of my practice runs are 7 and 4, NO complaints until I can get them just right! Thank you so so much for posting this simply adorable recipe! =] Joanna commented on Jun 07 11 at 3:25 pm What a mess!!! I followed directions exactly…the bottom colour, purple, rose 2/3 of the way up the jar…the blue and green barely visible, and the top 2 colours barely showed. they appeared more tie dyed than rainbow. The second batch did not bake all the way thru but bubbled over…..and also, as many others stated…the cake shrank away from the jar…a lot. As slices, once removed from the jar…the cake was very pretty bit that defeats the entire purpose of cake in a jar! Does anyone have any solutions??? carrie cook commented on Jun 08 11 at 11:42 am Wait, so are you telling me that I can just microwave the cake INSTEAD of baking it? Would all the preparation steps be exactly the same, and would it come out the same way? I mean, if that’s the case, I know what I’m doing… I DON'T BAKE OFTEN commented on Jun 11 11 at 7:03 pm I made 12 little 8 oz RAINBOW CAKES IN A JAR and they were PERFECT, AWESOME, and DELICIOUS ! :D I had NO problems with the jars turning brown AT ALL ! I followed CHELSEA J.’s advice a few post above here and adjusted the baking time as she did. I *think* I added 3 mins once more and TA DA !!! :) As for the ‘turning brown’ problem, I sprayed my little jars LIGHTLY with BAKER’S JOY [has flour in it] and again…. mine came out perfect ! I wish we could post pictures here, but if you’ll go to DUNCAN HINES on FB… I posted my picture on their wall. GOOD LUCK guys & gals… I WILL be making these again and using different colors. B.J. commented on Jun 12 11 at 6:15 pm This looks awesome! We saw this on Pinterest and are going to have to try it soon! Love the look of the mason jars… Lindsey Lindsey commented on Jun 14 11 at 7:43 pm how do i eat it? concerned eater commented on Jun 14 11 at 8:30 pm this wont break? I keep breaking glass because i put it through too much heat :< Lexy commented on Jun 16 11 at 12:04 am I made these at the weekend and they were great! I’ve made rainbow cake before so used a normal cake recipe (125g sugar/butter/ self raising flour, 2 tsps baking powder, 1 tsp vanilla essence, 1 egg, bit of milk) and they made 6 gorgeous cakes! I would advise putting boiling water in the oven instead of normal water, and having the oven very hot. :) Hannah commented on Jun 20 11 at 4:32 pm Awesome! I came across this on stumbleupon earlier today. Now, 4 of my friends and I are making them. :) We’re using a turkey baster to insert all the colors into the jar! Tell you how it turns out soon. We’re super excited about. We’re going to SF Pride tomorrow so it’s perfectly festive. Alicia commented on Jun 25 11 at 2:35 am We made several batches of these now and they are turning out great … except for the layering. Any ideas?. Sunny Haynes commented on Jun 27 11 at 8:43 pm Making these for 4th of July in red white and blue. :-) Jennifer commented on Jun 27 11 at 11:37 pm Can I use baby food jars? shawn commented on Jun 28 11 at 10:39 pm Super awesome !! Thank you for sharing !! I have a question?? Can I put the frosting and then send it out to my mom in Arizona I live in Texas ?? I just don’t want the cake nor the frosting to go bad ??? Polly commented on Jul 02 11 at 10:25 pm I’ve been looking for something fun to do for my daughter’s 6th birthday – I think this will be on our menu for sure! Lindsey @ Why Just Eat commented on Jul 03 11 at 9:23 pm Put the lid on it and send it to me please! angelique523 commented on Jul 06 11 at 12:15 am My mom and I are hosting a bridal shower this Sunday, and a few weeks ago we were trying to figure out what to make as the dessert. A few weeks ago, I stumbled upon this page and fell in LOVE with this recipe! The only thing we really did differently aside from using wide-mouthed jars (it’s all we could find after hunting through nearly half a dozen different store chains!) was instead of rainbow colors, we went with teal and white stripes. (Teal is the Bride’s favorite color/wedding colors, and white because – well, it’s a wedding shower!) Tonight is the test run to make sure they turn out alright before we serve them to guests – in other words, it’s a chance to eat cake before the bridal shower happens! haha. I’ll post an update once the shower occurs and hopefully I’ll send some pictures if I get the time to take some! :) Teresa commented on Jul 08 11 at 12:29 am I have made a similar recipe for cake in a jar and if you handle it all properly, you can turn put a seal lid and a ring on them, turn them over on a towel and they will self can themselves from the heat of the jar. my kids were eating them for a few months. they did do the shrinkage thing and there was some condensation in the jars but my girls are not fussy and still loved them ladiebuggg888 commented on Jul 22 11 at 1:50 am My question is: can you send frosting in the jar like this? Or if I sent it to a friend should they put on the frosting themselves? This looks delicious btw! Jess commented on Jul 31 11 at 5:54 pm This is the most fun I have had in a long time with a birthday cake! I used jelly jars and they cooked up great!! I wish I would have thought of jars to send birthday cakes to my kids when they were first at college. The 19 year old is going to love her cake in a jar! Sharon commented on Aug 03 11 at 11:43 am I was wondering if a marshmallow Fluff jar is too small for this recipe? lauren commented on Aug 06 11 at 11:23 am After reading these reviews, I am kind of nervous to do this recipe. I plan to make a cake in a jar for my boyfriend’s birthday, but decided that I am going to try and take a core out of the jar so that there is frosting throughout the entire cake. It may not go well, but at least it will be fun. Amanda commented on Aug 06 11 at 12:46 pm this looks awsome!! i am soo going to try this lol :) brittany commented on Aug 06 11 at 11:46 pm I’m gonna try this with my kids this week! I just link up to you from my post Briny Briny commented on Aug 07 11 at 2:50 pm this is super awesome! thanks for sharing -grace Grace commented on Aug 08 11 at 12:51 am ok so our stripes all blended to one nasty color…any tips? Bethany commented on Aug 08 11 at 11:10 pm Use a skewer to poke down in the middle of the cake to test if it’s done. I can think of all kinds of fun things to do with this idea. Thanks! Anita L. Williams commented on Aug 09 11 at 8:49 pm Love this! I made Whisk Kid’s rainbow cake which is gorgeous but way more work! I have some smaller mason jars and think this is a great idea – Thanks!! Capability commented on Aug 11 11 at 6:56 am Made these earlier this week w/my hubby & we layered, however, the layers didn’t work even close to what the pic displays. Our bottom color was prominent & others kinda just went in the middle. Once baked, the outside still had the same prominent color, but the middle was neat. It was sort of like tye-dye. We used only 3 jars for the cake mix bc it was about as full as the pic on here, but grew out of the top of the jar! This time, we are trying 1 color for each of the 4 jars this time. Going to see if that makes a difference. Still fun concept! StinaStew commented on Aug 12 11 at 9:16 pm love your post.. and i have here a good book omar commented on Aug 13 11 at 11:44 am I am impressed with the beautiful results, congratulations. I put forward on my French blog with a link to this article ( Miss Cuisine commented on Aug 18 11 at 5:20 am I need to try this with the neon dye. I have baked cakes in jars since the 80′s. If you use potholders and put the canning jar lids and rings on them, straight from boiling water, when the cake comes hot from the oven, and place the seals on, they will ping like jam, and will have a much longer shelf life…sealed and sterile! Lorrie Scott commented on Aug 18 11 at 10:54 pm I made these today!!! So cute!!! But after i let them cool a bit, i frosted and put a lid on the jar and when I went to serve them later they had shrunk inside the jar!! Like they got skinny in there…has that happened to anyone else? Any suggestions?? kelli commented on Aug 25 11 at 10:35 pm I saw this image on pinterest and tracked it down to here! I loved it so much that I featured it on my blog below! Thanks for the creativity!! Candin commented on Aug 26 11 at 5:58 pm I made these today and they looked horrible!! I put the layers bottom to top…purple, pink, blue, yellow, green…and they turned out like a big brown blob. What did I do wrong? Jessica Lang commented on Sep 04 11 at 1:50 am I loved it. I featured it in our blog with more than 1500 notes and people loving it!:) you’re welcome:D Justmyperfectwedding commented on Sep 07 11 at 7:24 pm omg i love it!!!! i will be trying this very soon , thank you so much Diane commented on Sep 12 11 at 5:35 pm do you put the jar in the oven ? gudrun commented on Sep 13 11 at 1:37 pm Has anyone tried this with the natural food colorings? My daughter can’t have artificial dyes but can have the natural food based dyes. I know they won’t be vibrant like these but would they work?
