Take box cake mix of your choice...add to it one can of soda (your choice).


Bake as directed on box...when cool, top with Cool Whip.

Good combinations:
Yellow cake mix and diet Mt. Dew
Cherry Chip cake with diet Dr. Pepper (or similar brand)
Devil's Food cake with diet cola
White cake with Diet cherry 7 up
German Chocolate with Diet Dr. Pepper ( or similar brand)

Are you saying not to add any eggs, oil or water, just the can of soda?
