Is this wierd?
Ever since that “Ask HG” question and the Extra segment ran, people have been emailing in about the diet soda cake. I guess I could have done a better job explaining that. SORRY! It could NOT be any easier. Just take a box of cake mix, and INSTEAD of adding the eggs, oil, water, etc., that the box tells you to add, just mix with 1 can of diet soda, and then bake according to box directions (or until a knife inserted into the center comes out clean). That’s it! You can do the same with brownie mix as well. Lots of people stick to Diet Coke and chocolate cake, but I have experimented with various cake and soda combos. Diet cream soda and diet lemon-lime soda bo th work GREAT with yellow and white cakes, as do fruity diet sodas like black cherry and orange. Have fun and be adventurous!
