Creamy Apple Crumb Pie

Directions

1. Line a 9-in. deep-dish pie plate or cast-iron skillet with crust; flute edges. In a large bowl, combine the sugar, cornstarch, cinnamon and allspice. Fold in the apples. Combine sour cream and vanilla; stir into apple mixture. Spoon into crust.
2. For topping, combine the flour, brown sugar and cinnamon in a bowl; cut in butter until mixture resembles coarse crumbs. Sprinkle over filling.
3. Bake at 400° for 25 minutes. Reduce heat to 350°; bake 25-30 minutes longer or until filling is bubbly and topping is golden. Cool on a wire rack. Refrigerate leftovers.
