Ingredients Nutrition

  • BARS
  • 1 (18 1/4 ounce) package yellow cake mix
  • 12 cup butter, softened
  • 1 large egg
  • 20 miniature peanut butter cups, chopped
  • 2 tablespoons cornstarch
  • 1 (12 1/4 ounce) jar caramel topping
  • 14 cup creamy peanut butter
  • 12 cup salted peanuts
  • 1 (16 ounce) can milk chocolate frosting (or use your favorite recipe)
  • 12 cup chopped salted peanuts


  1. MAKE THE BARS: In a large mixing bowl, combine the dry cake mix, butter, and egg; beat with an electric mixer on medium speed until no longer crumbly, about 3 minutes.
  2. Stir in the peanut butter cups; press the mixture into a greased 9 x 13 baking pan.
  3. Bake in a preheated 350°F oven for 18-22 minutes or until lightly browned.
  4. Meanwhile, in a saucepan, combine the cornstarch, caramel topping, and peanut butter until smooth.
  5. Cook over low heat, stirring occasionally, until the mixture comes to a boil, about 25 minutes.
  6. Cook and stir 1-2 minutes longer; remove pan from heat and stir in the peanuts.
  7. Spread the mixture evenly over the warm crust; bake for 6-7 minutes longer, or until almost set.
  8. Cool completely on a wire rack.
  9. Spread evenly with the frosting; sprinkle with chopped peanuts.
  10. Refrigerate for at least 1 hour before cutting into bars; store in an airtight container in the refrigerator.
  11. Bring to room temperature before serving; but they're just as yummy cold!
