Instructions: Preheat oven to 350. Prepare 2-9" round cake pans with cooking spray and flour; set aside. To prepare batter, combine cake mix, Dream Whip, and baking powder in a mixing bowl. In another mixing bowl, combine water, egg whites, oil, and vanilla. Mix dry ingredients with wet ingredients just until moistened. Bake for 25 minutes or until golden brown. Cool. Place cake layers, top sides up, in prepared cake pans. Pierce cake with large fork at 1/2" intervals. To prepare filling, stir 1 cup of the boiling water into each flavor of gelatin in separate bowls 2 minutes or until dissolved. Carefully pour red gelatin over 1 cake layer and lime gelatin over second cake layer.

Refrigerate 3 hours. Dip 1 cake pan in warm water 10 seconds; unmold onto serving plate. Meanwhile, to prepare topping, follow directions according to package. Spread with about 1/4 of the topping over top of first cake layer. Unmold second cake layer; carefully place on first layer. Frost top and sides of cake with remaining topping.

Refrigerate 1 hour or until ready to serve.
