"In West Virginia, blackberries used to grow wild near our neighborhood. My Grammy would make me this recipe after we would go berry-picking. This recipe is also good with blueberries and raspberries."
1Preheat an oven to 350 degrees F (175 degrees C).
2Place the cake mix into a mixing bowl, and work in the butter until the cake mix resembles corn meal. Spread the berries into a 9x13-inch glass baking dish, and sprinkle evenly with the crumb topping.
3Bake in the preheated oven until the berries are tender, and the crumb topping is golden brown, about 30 minutes.
