Use one box angel food cake mix and one box any other flavor cake mix. Mix together in large ziplock bag. Put 3 tablespoons mix into coffee cup and add 2 tablespoons water, mix well. Put in microwave for 1 minute. You have single serving cake.
We tried it but didn't want to waste two cake mixes if it was nasty. I used 1/8 cup of each and mixed them together then measured out 3 T mix and added the water into a glass measuring cup. Not too sweet but edible. Would be better with my buttercream frosting but I'm too tired tonight to make any. Beats the heck out of a pan of brownies in the evening when I want sweets. I usually eat half the pan at night and the other half for breakfast and I do not NEED that many calories.
I tried a similiar recipe years ago that was cake in a cup or brownie in a cup that took cocoa, sugar, etc and was disgusting.
