simply cake mix & can of soda. Nothing else. YES- it worked! orange pop taste was subtle- smells great as it cooks. I had used cream cheese frosting, but that was a bit strong. Next time plain vanilla frosting or cool whip.
Sprite Cake: Mix one box of strawberry cake mix with a 12-ounce can of Sprite (can use Sprite Zero for a diet version). Cook for 25 to 30 minutes on 350 or until a toothpick comes out clean. Cut into squares. Top with Cool Whip and fresh berries. I'm so doing this for a carry in/reunion.
