I have had this recipe for years -- since I was a teenager! The top comes out very crunchy. It's not like your typical apple crisp topping. If you want, you can substitute Raw Sugar for 1/2 of the sugar in the recipe.
If using canned apple pie filling, place apples and water (1/3 cup) in greased 9 x 13 pan.
If using fresh apples, slice and place in medium bowl. Then sprinkle approximately 3-4 tablespoons of sugar depending on the sweetness of the apples plus 1 tablespoon cinnamon, and a pinch of salt and mix. Then place in pan. Pour 1/2 cup of water into pan.
For the topping: Cream butter and sugars together. Add flour and cinnamon. Mixture should be fine. Sprinkle on top of apples in pan.
