Filling:

Melt the butter in a pan and add the rest of the ingredients. Cook until everything is soft and the liquid starts to evaporate some. Let it get as thick as you want. Pour into greased 8×8 inch pan.

Topping:

Blend all ingredients except the oats with a pastry blender to combine well. Add oats. Stir well. Sprinkle over hot apple filling.

Bake at 400 degrees until topping is brown.
