Low Fat Chocolate Cake

1 can 12 oz. Diet Coke
1 Milk Chocolate Cake Mix

Mix diet coke with dry cake mix and bake according to box.

*Note- Since this cake has so little fat, it is a little more delicate. It should be baked in a 9x13 dish. I haven't had much luck using frosting, it weighs the cake a little too much. So I tried cool whip or chocolate cool whip, it works better. And I bet a homemade chocolate mousse would be awesome!*
