Hi this is in my opinion a great way to have apple pie, without having another layer of dough on top and when it is done I would top it off with vanilla ice cream.

Cut in 3 tablespoons butter, until mixture is crumbly. Spread on pie and bake about 20 to 25 minutes at 350 degrees.
All the best to you
