Gooey Peanut Butter Cup Bars

I wanted a different recipe that could stand out among the numerous trays of desserts served at potlucks and parties. With a marshmallow glaze and rich peanut butter in every bite, these brownies are always popular. —Carla Benckert, Albrightsville, Pennsylvania

    These peanut butter cup bars are a great recipe! I found that I'd needed a 30-minute baking time-other than that-these bars were lip-smacking GOOD to the last bite! delowenstein
