Prepare your favorite fruit pie filling - cherry, blueberry, raspberry, elderberry or raisin. Pour it into an unbaked pie shell and top it with the following crumb mixture.
In a bowl, mix together the dry ingredients, then add the melted butter and mix it thoroughly until all the ingredients are moistened.
Bake the pie at 425 °F for 25 to 30 minutes or until the filling boils and the crumbs are nicely browned. This recipe makes enough crumbs for approximately 3 pies.
