Chocolate Peanut Butter Crunch Bars are quite a mouthful! These layered bars have a little bit of everything: a crispy chocolate base, a stripe of peanut butter fudge, a layer of chocolate-peanut fudge, AND a smooth chocolate icing on top! If you like sweet-and-salty, if you like crunchy-and-chewy, or if you like chocolate-and-peanut butter...these bars are for you!

These bars have a lot of layers and a lot of steps, but they’re all fairly basic, so don’t be intimidated—it is easier and faster than it appears!


  • 1 cup/6 ounces chocolate chips (or chopped semi-sweet chocolate, divided use)
  • 4 ounces plus 1 tablespoon butter (unsalted, divided use)
  • 1 cup crisped rice cereal
  • 1 cup/9.5 ounces crunchy peanut butter (divided use)
  • 1/8 teaspoon salt
  • 1 1/4 cups/5 ounces powdered sugar

Steps to Make It

  1. Gather the ingredients.

  2. Prepare a 9x5-inch loaf pan by lining it with aluminum foil and spraying the foil with nonstick cooking spray.

  3. Place 1/4 cup of chocolate chips and 1/2 tablespoon of butter in a medium microwave-safe bowl. Microwave until melted, stirring after every 30 seconds to prevent overheating.

  4. Stir in 1/2 cup of crunchy peanut butter, and once incorporated, add the crisped rice cereal and stir until well-combined. Scrape this mixture into the prepared pan and press it in an even layer. Refrigerate to set the crust while you prepare the next layer.

  5. Place 1 stick/4 ounces of butter and the salt in a medium saucepan over medium heat. Melt the butter, and then stir in the remaining 1/2 cup of crunchy peanut butter. Stir until completely incorporated and smooth.

  6. Add the powdered sugar and stir until smooth. Pour half of the peanut butter fudge mixture on top of the bottom layer in the pan, and spread evenly. Reserve the other half, and place the pan back in the refrigerator to set.

  7. In a small microwave-safe bowl, melt 1/4 cup of chocolate chips. Pour the melted chocolate into the remaining peanut butter fudge in the saucepan, and stir until well-combined. Spread the chocolate peanut butter fudge over the peanut butter fudge in the pan and smooth it into an even layer.

  8. Place 1/2 cup of chocolate chips and 1/2 tablespoon butter in a small microwave-safe bowl and microwave until melted and smooth. Pour the melted chocolate on top of the fudge layer and smooth it into an even layer. Refrigerate to set the bars completely, about 1 hour.

  9. Once set, remove the bars from the pan using the foil as handles. Cut the bars into small squares to serve. Enjoy!
