Diet Coke Float Cake

Rev BJ Friley


I always joked with Brenda that there was nothing diet or healthy about this recipes, but it was soooooo good.

Ways to make a "better" cake:
- Mix a chocolate cake mix with a box or prepared sugar-free chocolate pudding (do the same for strawberry or vanilla cakes)
- Instead of using oil, substitute applesauce (same as oil amount) or butterbuds (3 Tbsp liquid butterbuds)
- Instead of using eggs, substitute egg beaters or egg whites
