medium (6 cups) apples, peeled, cored, sliced
cup firmly packed brown sugar
cup uncooked old-fashioned oats
cup all-purpose flour
teaspoon ground cinnamon

Heat oven to 375°F. Place apples into ungreased 9-inch square (2-quart) baking dish. Combine brown sugar, oats, flour and cinnamon in medium bowl; cut in butter with pastry blender or fork until mixture resembles coarse crumbs. Sprinkle sugar mixture over apples. Bake for 25 to 35 minutes or until apples are tender and topping is golden brown. Serve warm with ice cream, if desired.
