Preheat oven to 400 degrees. Wash your apples.

In a large bowl, make the streusel topping by combining the flour, oats, brown sugar, sugar, salt, and cinnamon. Mix together and cut in butter until coarsely crumbled.

Take 4 of your apples and slice the tops off. Clean out the flesh from the inside with a grapefruit spoon and knife, set aside.

Chop the remaining 4 apples into small pieces and add to a skillet with the butter, brown sugar, and cinnamon.

Simmer until the apples are soft enough to easily bite through, yet not mushy, and the butter and sugar have become a "caramel-like" sauce. About 10 minutes.

Scoop the apple filling into the hollowed out apples and top with the homemade streusel.

Bake for 10 - 15 minutes or until golden brown and bubbly.

Enjoy!!
