and let's face it, we all do at times, I tried something goofy but it worked! from the "Hungry Girl" cookbook & website
1 cake mix - whatever kind, and 1 can of diet soda! OMIT the eggs & oil the package says to put in.
I tried a chocolate cake with diet coke, and a lemon cake with diet 7 up and both were amazing and not greasy, just kind of awesome -- made cupcakes with it and no one noticed they weren't 'real'
i know cake mixes are the devil, as they have hydrogenated frankenstein ingredients, but i thought i'd pass along the info if anyone was interested!
