Pour cans of filling or fruit cocktail in bottom of Dutch oven. Sprinkle cake mix over top of fruit, DO NOT STIR! Sprinkle with cinnamon and cut pads of butter and let fall on surface. DO NOT STIR, it will burn. Cover and bake until bubbly and top is lightly browned, about 30-45 min. Any combination of fruits can be used. I recommend 1 can apple filling and 1 can of fruit cocktail.
