1 c. crunchy peanut butter
1 1/2 c. graham cracker crumbs
1 c. butter, melted (2 sticks)
3/4 lb. confectioners sugar

Melt chocolate pieces in the top of a double boiler, while they are melting, mix together the rest of the ingredients. Pat into a 13 x 9 inch pan. Spread the melted chocolate on top, then chill and cut into small squares. These freeze well.
