The ladies and I just celebrated their Gammy's birthday with quite possibly the tastiest cake ever. We made her a key lime soda pop cake with whipped topping. This trend of baking cakes with just soda is a dieter's dream. It cuts the calories way down but you don't lose the taste.
We used Betty Crocker white cake mix, but any boxed mix will do. The "key" was the key lime Stewart's soda. One 12oz bottle of a flavored Stewart's soda, one box of cake mix, blend together and bake at 350° for 30 minutes. We topped ours with light whipped topping. It was grand. I believe next up we'll try Stewart's cherry.
