(Grandma Jones and Aunt Jacque taught me this simple one.)
1 sleeve graham crackers
1/2 cube butter
2 T. powdered sugar
Roll graham crackers until crumbs. In a pan, melt butter on medium. Pour crumbs into pan and add powdered sugar. Mix well. Grease pie tin and pack the crumbs in the tin. Bake for 15 minutes at 325.
