1 1/2 cups graham cracker crumbs
1 cup butter, melted
2 1/2 cups icing sugar
1 cup peanut butter, crunchy or smooth
2 cups chocolate chips
In a large bowl combine graham cracker crumbs, butter, icing sugar and peanut butter. Mix until smooth.
Spread mixture in lightly greased 9 X 13 pan. Chill in refrigerator for about 15 minutes.
Melt chocolate chips in double boiler and spread over chilled peanut butter mixture.
It's easier to cut the squares before chocolate is completely set.
To make cups, follow same procedure using small aluminum foil pie plates.
