Melt butter in a small saucepan and allow to cook until lightly browned. Turn off heat and set aside.
Mix together flour, sugar, salt, and milk in a small bowl. Stir in butter to combine. Pour into a small (4 cup) baking dish and sprinkle fruit over the top. Bake 20-30 minutes or until a toothpick inserted removes clean. Allow to cool slightly before digging in.
