Ingredients

The following ingredients have 4 Servings
  • 1 (1 lb 6.5 oz) box Betty Crocker® Original Supreme brownie mix
  • Water (vegetable oil and eggs called for on brownie mix box)
  • 1/2 cup butter (softened)
  • 3/4 cup creamy peanut butter
  • 2 cups powdered sugar
  • 2 teaspoons milk
  • 1 cup semisweet chocolate chips
  • 1/4 cup butter

Instruction

  • Heat oven to 350°F. Grease bottom only of 13×9-inch pan with cooking spray or shortening. (For easier cutting, line pan with foil, then grease foil on bottom only of pan. I do this all the time when I make brownies and bars)
  • In medium bowl, make brownie mix according to the package directions. Spread in pan. Bake according to package directions. Cool completely, about 1 hour. You can speed this up by cooling in the refrigerator.
  • In medium bowl, beat filling ingredients with electric mixer on medium speed until smooth. Spread mixture evenly over brownie base.
  • In small microwavable bowl, microwave topping ingredients uncovered on High 30 to 60 seconds; stir until smooth. Cool 10 minutes; spread over filling. Refrigerate about 30 minutes or until set. For brownies, cut into 9 rows by 4 rows. Store covered in refrigerator. (I take it out or the fridge about 15 minutes before serving. This allows the chocolate on top to soften a little)
