5 cups apple slices (Golden Delicious preferred)
1/2 cup sugar
1 teaspoon ground cinnamon
1/3 cup sugar
3/4 cup all-purpose flour
6 tablespoons cold butter, cut in small pieces
1 unbaked 9-inch pie shell
Preheat oven to 400°F.
Peel and slice the apples into quarter-inch slices until you have 5 cups of apple slices. Put apple slices into the unbaked pie shell.
Mix together the 1/2 cup sugar and cinnamon, and sprinkle evenly over the apple slices.
Prepare the crumble top by mixing the remaining 1/3 cup sugar with the flour. Cut in the butter with a pastry blender or fork until ingredients are incorporated. Sprinkle crumble mixture on top of pie.
Bake at 400°F for 35 to 40 minutes until crumble top is golden brown
