I finally made the cupcake recipe that I saw on the forum. I used.
1 Box of Orange Supreme Cake Mix
1 Can of Diet Orange Soda
2 Egg Whites
Cool Whip Vanilla Frosting

You just blend all of these ingredients together and bake as cupcakes. You leave out the whole eggs, oil, and water it calls for. I could not even tell the difference. I am going to use this recipe for when I make birthday cupcakes/cake now! This was definitely one of the best recipes on here!
