My mom made these when we were just little tykes. It was soon after they came out with the Reese's peanut butter cups. She made all kinds of sweets w/ those candies, but these were always the favorite. No bake and most likely you'll have the ingredients already on hand.
Cut parchment paper to fit a 9" x 13" pan, spray the paper w/ cooking spray.
In a food processor, place graham crackers, powdered sugar and peanut butter. Pulse until mixed well. Pour in butter and blend until combined.
Press mix into the pan. In microwave safe bowl, add chocolate chips and cream. Microwave in 30 second increments, stirring after each time, until melted and smooth.Spread chocolate over peanut better mix. Chill in refrigerator until set, about 2 hrs. Cut into bars. Seal in tightly sealed containers.
