We made cupcakes using this recipe and they were YUMMY! Replacing the eggs, oil, water, etc. with diet soda adds no additional calories to the cake mix, but you still end up with a light and moist cake!
I used yellow cake mix and diet Sprite. (I think clear-ish sodas are best for yellow and white cakes and dark sodas are best for chocolate cake and brownies.) I still plan on experimenting with different flavored sodas and different flavored cake mixes.
And of course, I'll need help eating all this cake.....
anyone want to come over for dessert???? :)
