Preheat oven to 375 degrees F.

Oat Crumble Topping: In a small bowl mix flour, oats, brown sugar, cinnamon and butter. Add butter and cut in with a pastry blender or fork into very small pieces.

Prep Peaches: Peel peaches, or keep the skin on. Slice in half and remove the pit. Place the peaches face-up in a small baking pan.

Assemble: Add a big spoonful of crumb topping to the center of each peach.

Bake for about 12-15 minutes or until crumb topping is golden brown.

Serve with a scoop of ice cream and/or a drizzle of caramel sauce, if desired.
