Terrific party dessert. Easily make 24-48 single serving Neopolitan cakes. Bake in canning jars, put lids on when you take them out for cooling, and watch them self-seal. Refridgerate until ready to serve. Takes 3 boxes of cake mix (1 for each flavor) use half of each for 24 servings or all for 48 servings. Measurements and details at the link.
This is a GREAT cake to send to soldiers! I have done this and sent frosting separately and is greatly appreciated. Cake in a Jar. Follow the receipe for the cake, poor into a jar, bake, until cake springs, or tested with cake tester or toothpick comes out clean, remove from oven place top on and let seal. Be sure to spray your jar before pouring mix into jar.
