I got this recipe from my aunt when I was college and found I could make them in my dorm using the microwave in the lobby and my 9 x 13 pan (because don't all college girls have a 9 x 13?). I had a group of guy friends who formed a hockey league on Thursdays and lovingly called me their "hockey mum", mostly because I had a car and drove them to games. I made these bars for them on a regular basis, so they became known as "Hockey Bars".
10 graham crackers, crushed (I put them through a food processor, but they can be crushed by putting them in a ziplok bag and smushing them with a cup or meat tenderizer!)
1 c. peanut butter (creamy or crunchy)
1 stick butter, divided (and softened)
2 1/2 c. powdered sugar
1 c. semi-sweet chocolate chips
Combine graham cracker crumbs, peanut butter, 3/4 stick of butter and powdered sugar. Press into bottom of a 9 x 13 pan. Cool in fridge or in freezer to speed up the process!
Melt chocolate chips and remaining butter (1/4 stick) in microwave until smooth. Pour on top of PB mixture and chill in fridge until hardened.
Cut into bars and enjoy!
