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.
