Gluten-Free Peanut Butter Stuffed PB Krispy Bars. Frosted in chocolate and topped with PB M&Ms, this dessert is perfect for midnight munchies, kids parties and the peanut butter lover in your life!

What happens when you take traditional krispy bars, turn them gluten-free, then stuff them to the max with a creamy layer of peanut butter? You get this recipe that is so good, you might not want to share! Once you try these upgraded bars you will never go back to the old-school version. 

Because we know a small batch of these babies won’t be nearly enough, we’ve supersized the recipe, prepped it in a Good Cook 9×13″ baking pan and topped it with PB M&M’s. Because the peanut butter lovers in our life deserve triple the peanut butter, topped with chocolate. Wouldn’t you agree?

Whip a batch up for lazy weekends. You can nibble on a square every time you walk into the kitchen. Or tote a pan to your next potluck. If you love bringing the dish that “wows” the crowd, this recipe is sure to be a banger!

Upgrade classic krispy bars with an irresistible layer of creamy peanut butter.

  • Prep Time: 10
  • Cook Time: 10
  • Total Time: 20 minutes


  • 1 stick butter
  • 1 cup peanut butter
  • 1 pound gluten-free powdered sugar
  • 3-4 Tbsp milk


In a large bowl, prepare the Peanut Butter layer by beating together the butter, peanut butter, powdered sugar, and milk, until smooth. Set aside. In a large, Good Cook pot, prepare the Krispy Bar layer by melting the butter over medium heat. Add the mini marshmallows and stir until melted. Stir in the krispy rice cereal until well coated with the marshmallows. Spread half of this mixture into a 10×13″ Good Cook bar pan. Spread the peanut butter layer on top, then add the rest of the krispy rice layer over the peanut butter layer. In a small, microwave-safe bowl, melt the chocolate chips and butter together. Stir until smooth. Spread over the top of the krispy rice bars. Press the candy into the top of the chocolate layer. Allow to cool completely before slicing and serving.
