Graham apple bake

This recipe originally calls for oats. I didn't have that but I had some graham crumbles lying around from a previously made cheese cake. It was delicious and I used up the left over apples, flour and sugar around the house.

5 cups Granny Smith apples, pared, cored, and sliced
1/2 - 3/4 cups sugar
1 teaspoon ground cinnamon
Streusel Topping

Streusel Topping
3/4 cup flour,
1/2 cup quick rolled oats
1/4 cup each packed brown sugar
1/4 white sugar;
Put in 1/2 cup room temp or soft butter or 1 stick of butter until crumbly mixture is formed.

1) Toss apples with sugar and cinnamon; spread in bottom of 11X8X2 inch baking dish. Sprinkle with Streusel Topping. Bake at 350 degrees F. 35-40 minutes.
