Peanut Butter Pretzel Bars

Directions

• Line a 13x9-in. baking pan with foil, letting ends extend up sides. Set aside 1-1/2 cups pretzels for topping. Pulse remaining pretzels in a food processor until fine crumbs form. In a large bowl, mix butter, peanut butter, confectioners' sugar and pretzel crumbs.
• Press into prepared pan. In a microwave, melt chocolate chips and shortening; stir until smooth. Spread over peanut butter layer. Break reserved pretzels and sprinkle over top; press down gently. Refrigerate, covered, until set, about 1 hour. Lifting with foil, remove from pan. Cut into 48 bars.
