From my recipe book... February, 1992! Super easy and tasty!
1 cup icing sugar
1 cup graham wafer crumbs
1/2 cup smooth peanut butter
1/4 cup plus 1 tablespoon melted margarine or butter
Use a mixer to combine thoroughly.
Press into a 7 x 11 pan.
1 cup milk chocolate chips
Melt in microwave: 20 seconds on high, stir;
20 - 30 seconds more, stir again.
Spread over peanut butter layer. Chill.
Remove from refrigerator 10 minutes before
cutting into squares.
Note: This recipe can be doubled - use a 9 x 13 pan.
