Peanut Butter and Chocolate Cookie Bars

These peanut butter-enhanced chocolate bars boast an enchantingly chewy oatmeal crust. Do make sure that you use quick-cooking oats as the bars need their finer texture. If old-fashion-style oats are all you have, pulse them a few times in a food processor or blender to break them up. They'll work just fine!

  • 1 cup packed brown sugar
  • 2/3 cup butter
  • 1/4 cup dark- or light-color corn syrup
  • 1/4 cup peanut butter
  • 1 teaspoon vanilla
  • 3 1/2 cups quick-cooking rolled oats
  • 1 12 ounce package (2 cups) semisweet chocolate pieces
  • 1 cup butterscotch-flavor pieces
  • 2/3 cup peanut butter
  • 1/2 cup chopped peanuts
Preheat oven to 375 degrees F. In a medium saucepan combine brown sugar, butter, and corn syrup. Cook and stir over medium-low heat until smooth. Remove from heat. Stir in the 1/4 cup peanut butter and vanilla until smooth.
Place oats in an extra-large bowl. Pour brown sugar mixture over oats, stirring gently until combined. Press oat mixture evenly into bottom of foil-lined 13x9x2-inch baking pan. Bake in preheated oven for 10 to 12 minutes or until edges are lightly browned.
Meanwhile, in the same saucepan combine chocolate pieces and butterscotch pieces. Cook and stir over low heat until melted. Stir in the 2/3 cup peanut butter until smooth.
Slowly pour chocolate mixture over hot crust, spreading evenly. Sprinkle with peanuts. Cool in pan on a wire rack. (If necessary, chill until chocolate is set.) Use foil to lift uncut bars from pan. Cut into bars. Makes 48 bars.
