12 oz. frozen fruit - i used a cherry berry blend
white cake mix (don't use one with pudding in the mix)
Spray a 9x13 pan and spread frozen fruit evenly in bottom of the pan.
Sprinkle dry cake mix over the frozen fruit.
Slowly pour the 7up over the dry cake mix.
Bake at 350° for 1 hour.
I let mine cool but I'm guessing it would be great served warm with either ice cream or whipped cream
