Preheat oven to 375°F and grease the baking dish. Peel (if you like) and core apples, slice or cube and spread them in the baking dish. Set aside.
Mix remaining ingredients together until well incorporated and sprinkle over sliced or cubed apples.
Bake 30 minutes or just until bubbly and browned. Serve warm with a scoop of vanilla ice cream.
Enjoy!
