Combine all the crust ingredients in a bowl. Mix well and pat into the bottom and sides of a pie pan. Don't roll the dough out.
Use a pastry blender to cut the butter into the flour and sugar, and mix until crumbly. Set aside.
Combine all ingredients, except the apples, in a bowl. Mix well, then toss the apples in the mixture. Put the apple filling into the unbaked pie crust.
Top with crumb topping.
Place the pie inside a brown paper bag. Once the pie is inside, roll up the top of the bag and close it together with either staples or large paper clips.
Place the bag on the lowest shelf in the oven. Bake at 350 for 90 minutes. Don't open the bag until the time is up and you have let it cool outside the oven for about 5 minutes.
Allow the pie to cool to room temperature.
Serve with vanilla ice cream.
