Lay the pie crust into the bottom of a deep dish pie plate. Crimp the edges and cut any excess off.
In a bowl, beat the cream cheese until smooth. Add in the sugar and vanilla; mix well. Add egg then beat until smooth. Spread over the bottom of pie shell.
Chill for 30 minutes in the refrigerator.
In a large bowl, beat the Pumpkin Pie Layer ingredients together until smooth. Carefully pour over the cream cheese layer. Cover the edge of the pie crust with foil.
Bake at 350° for 30 minutes. Remove the foil then bake 25 minutes longer.
In a small bowl mix the flour, brown sugar, and butter until crumbly; stir in pecans. Sprinkle over the pie in the oven.
Bake 10-15 minutes more or until a knife inserted near the center comes out clean. Cool on a wire rack. Store in the refrigerator.
Notes
You can divide the fillings and make this into two shallow 9-inch pies as well, if you want the recipe to go further! Just use another pie crust.
