Crumb crust is an alternative to the traditional single pie crust. The crumb crust can be made from a variety of cookies or crackers. Crumb crusts can be made from graham crackers, chocolate or vanilla wafers, sandwich cookies, and gingersnaps. The flavor of the crust can be enhanced by adding pecans, almonds, and other nuts. Spices, such as ginger, cinnamon, and nutmeg can also be added. See the instructions below on how to make a crumb crust.
