Two 12-ounce bags of frozen mixed berries
1 box of white cake mix (no pudding)
1 7-up diet can or sierra mist (clear soda)
Place the frozen fruit on a 9×13 baking dish. Add dry pastry mix on top. Slowly pour the soda over the pastry mixture. DO NOT stir the pastry mix and pop – this will give you a “crust”. If you stir both, you will have a cake for a topping.
Bake 350 for 45-50 minutes.
