When I was in high school, I took these sweet and crunchy squares to bake sales— and they were the first to sell out. I still make them for family and friends who love the classic combination of chocolate and peanut butter. —Christy Asher, Colorado Springs, Colorado
In a bowl, combine cracker crumbs and butter. Stir in sugar and peanut butter. Press into a greased 8-in. square pan.
In a microwave or double boiler, melt the chocolate chips and stir until smooth. Spread over peanut butter layer. Chill 30 minutes; cut into squares. Chill until firm, about 30 minutes longer. Store in the refrigerator.
