Brownie in a CUP! This would be great as a gift.sharpie the instructions onto mug, add the dry ingredients and wrap. (My daughter successfully made cake / brownie in a cup, her solution for not having permission to use the oven when Mom's at work)
Banana Bread In-A-Jar. If you put a canning lid on them when they first come out of the oven, they seal. Dessert in a jar for Christmas. Could do pumpkin bread, carrot cake, and applesauce cake. You can do it with any moist bread or cake.
For those days you want to make one cookie: 1 tbsp melted butter - 1 tbsp white sugar - 1 tbsp brown sugar - 3 drops of vanilla - pinch of salt - 1 egg yolk - c flour - 2 tbsp chocolate chips Microwave seconds In a cup = single-serving deep dish cookie.
