1 c. peanut butter
2 stick butter, melted
1 c. graham cracker crumbs
1 box powdered sugar
1 pkg. semi-sweet chocolate chips

Combine peanut butter (crunchy or smooth), butter, graham cracker crumbs, and sugar. Press into oblong pan greased with butter. Melt the chocolate chips in saucepan or microwave and pour over peanut butter layer.

IMPORTANT: Place pan in freezer for 5 minutes just to let chocolate harden a little. Remove from freezer and cut into squares (chocolate cracks if you leave in the freezer too long).
