In a large bowl combine all filling ingredients ans set aside.
In a 9-inch regular pie pan fit crust. Crimp edges decoratively. Add filling.
Combine topping ingredients with a pastry blender until the mixture resembles crumby pebbles. Sprinkle over top of the pie.
Bake at 400°F (204ºC) for 15 minutes. Reduce oven temperature to 350ºF (177ºC) and continue to bake for 35 minutes or until the apple mixture is bubbly and the topping is nicely golden brown.
Notes
Rest: One of the most important ingredients in any pie isn’t even on the list — and it’s time. Let your apple pie filling recipe rest! Letting the apples sit in their seasoning allows the natural liquid to well up and run off the apples, which gives you a dryer, more held-together filling after baking, instead of a soggy mess of goo. So have patience!
