In a large bowl, combine the first six ingredients. Transfer to a 9-in. square baking dish coated with cooking spray. For topping, combine the oats, brown sugar, flour and cinnamon. Cut in butter until mixture is crumbly; sprinkle over fruit.
Bake at 350° for 30-35 minutes or until topping is golden brown and fruit is tender. Serve warm with ice cream. Yield: 8 servings.
