1 1/2 sticks butter
1 c. crunchy or smooth peanut butter
2 c. graham cracker crumbs
2 c. powdered sugar
1 (12 oz.) pkg. chocolate chips

Melt butter and peanut butter together. Add graham cracker crumbs and powdered sugar next. Mix together well, then press into 9 x 12 inch pan. Chill until firm, about 10 minutes. Then melt 12 pounces chocolate chips, spread over bottom layer. Chill until set. Cut into squares quickly before chocolate cracks. This is Jeremy's favorite!
