Preheat oven to 350°F.
Combine chunked apples with applesauce and cinnamon.
Place in a lightly greased 10-inch round casserole dish or glass Pyrex dish (I do not suggest using an aluminum pan).
You can also divide the mixture into ramekin cups.
Mix all crumble ingredients together with a spoon until the mixture gets crumbly.
Sprinkle over apple mixture and bake uncovered for 1 hour.
