Author Cookie Madness


  • 1/4 cup butter softened
  • 1/4 cup creamy peanut butter
  • 1/4 cup granulated sugar
  • 3 tablespoons plus 1/2 cup brown sugar divided use
  • 1/4 teaspoon vanilla extract
  • 1 large egg separated
  • 1/2 cup all-purpose flour 2.25 oz (spoon and sweep)
  • 1/4 cup chopped peanuts
  • 1/2 cup semi-sweet chocolate chips
  • 1/2 cup mini marshmallows


  • Preheat oven to 350 degrees F. Line an 8 inch square pan with foil and spray with baking spray or grease well and dust with flour.
  • Mix together the butter, peanut butter, granulated sugar, 3 tablespoons of the brown sugar, vanilla and egg yolk. Add flour and stir just until mixed. Stir in the peanuts. Spread batter across bottom of prepared pan using wet fingers.
  • Sprinkle the chocolate chips and marshmallows evenly over the batter and press lightly.
  • Beat the egg white until stiff and beat in the brown sugar. Spread egg white mixture over marshmallow mixture (I stopped about 1/4 inch from the edges of pan leaving edges uncovered) and bake at 350 for 25 minutes or until meringue is brown.
  • Cool in pan set on a wire rack for a few hours. Lift foil from pan and cut into squares. At this point, I recommend chilling the bars/squares for a while. They're easier to cut when cold, and should you decided to cut them into even smaller squares, it will be easier.
  • Makes 16 squares (of which some will be crusty edges).
