Place fruit in a cast iron skillet or 2-quart square baking dish. Stir in the granulated sugar.
For the topping, in a medium bowl combine the oats, brown sugar, flour, and spices. Cut in butter until mixture resembles coarse crumbs. Or simply dice butter and sprinkle butter over mixture.
Bake for 35 to 40 minutes or until fruit is tender and topping is golden.
