Preheat oven to 400° F.
Prepare the crumble topping: In a medium bowl whisk together flour, oats, brown sugar, sugar and cinnamon. Cut in the butter with a pastry knife, or two forks until mixture is crumbly. Set aside.
Peel and chop 2 of the apples. Add chopped apples, butter, brown sugar, and cinnamon to a medium sauce pan and stir over medium heat for 8 minutes or until apples are tender. Remove from heat.
Chop the tops off of the remaining 6 apples and use a spoon to scoop out the flesh. You don't scoop all of it out, just enough to make a "bowl" for the filling.
Fill scooped-out apples with the warm apple filling from sauce pan. Top with a generous amount of crumble topping.
Place stuffed apples on a baking sheet and bake for 10-15 minutes until crumble topping is crispy. Serve warm with vanilla ice cream and caramel sauce. Enjoy! ♥
