Two 12-oz bags frozen mixed berries
1 box white cake mix (no pudding). I used French Vanilla
1 can of diet 7-up or sierra mist (clear soda). I used Ginger ale
Place frozen fruit in a 9x13 baking dish. Add dry cake mix over the top. Pour soda slowly over cake mix. DO NOT stir the cake mix and the pop - this will give you a 'crust'. If you stir the two, you will hsve a cake like topping. Bake 350 for 45-50 min. You may be able to use frozen peaches instead of mixed berries. Serves 16
Note: It says to not mix it, but I had powder on top of mine after it came out of the oven. It still tasted really good.
