Peanut Butter-Chocolate Bars

Peanut Butter-Chocolate Bars
1/2 cup butter
1 1/2 cup graham cracker crumbs
14-oz. can sweetened condensed milk
1 cup peanut butter chips
12-oz. pkg semi-sweet chocolate chips
Melt the butter in a 13x9 inch baking dish in a 350 F oven. When melted, tilt the baking dish to evenly coat the bottom with butter. Sprinkle the graham cracker crumbs over the butter. Press lightly and evenly over the bottom of the dish. Pour on the sweetened condensed milk and then top with the peanut butter chips. End with the semi-sweet chocolate chips. Press down on the top layer so the chips are in the sweetened condensed milk. Bake at 350 F for 25 minutes or until the top is golden. Cool and cut into bars. Makes 2 to 3 dozen bars
