Frosted Peanut Butter Bars


  • ⅓ cup shortening
  • ½ cup peanut butter
  • 1½ cups packed brown sugar
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1 ½ cups all-purpose flour
  • 1 ½ teaspoons baking powder
  • ½ teaspoon salt
  • ¼ cup milk
  • ⅔ cup creamy peanut butter
  • ½ cup shortening
  • 4 cups confectioners’ sugar
  • ⅓ to ½ cup milk
  • ¼ cup semisweet chocolate chips
  • 1 teaspoon shortening


  1. In a large bowl, cream the shortening, peanut butter and brown sugar until light and fluffy. Beat in eggs and vanilla. Combine the flour, baking powder and salt; gradually add to creamed mixture alternately with milk, beating well after each addition.

  2. Transfer to a greased 15-by-10-by-1-inch baking pan. Bake at 350 degrees for 16-20 minutes or until a toothpick inserted near the center comes out clean. Cool on a wire rack.

  3. For frosting, in a small bowl, cream the peanut butter, shortening and confectioners’ sugar until light and fluffy. Gradually beat in enough milk to achieve spreading consistency. Frost bars.

  4. In a microwave, melt chocolate chips and shortening; stir until smooth. Drizzle over frosting. Store in the refrigerator.
