Place the pie crust into a deep 9" pie pan and flute the edges of the pie crust as desired. Set pie crust aside. Preheat the oven to 400 degrees F.
For The Filling
Combine the filling ingredients in a large bowl and toss together until evenly coated. Spoon the mixture into the crust-lined pie pan, mounding the apples towards the center.
For The Crumb Topping
Combine the topping ingredients in a medium bowl and use a pastry blender or sturdy fork to mix until crumbs form. Sprinkle this mixture over the apples.
Bake for 45 to 55 minutes or until the pie crust and crumb topping are a deep golden brown and the filling begins to bubble. After 20 minutes of baking, cover the top of the pie and crust loosely with foil to prevent over browning.
Let pie cool on wire rack. Cool for at least 3 hours before slicing and serving to allow juices inside pie to settle.
