Peanut Butter Rice Crispy Treats

Deliciously Peanut Buttery Peanut Butter Rice Krispy Treats

For years I struggled with peanut butter flavored rice krispy treats. I never thought they were very good, and they certainly were never very strong in peanut butter flavor. What is the point if they don’t taste like peanut butter?

So, I decided to make my own.

I spent years testing it, trying different ingredients, and adjusting the amounts, until I finally found the perfect recipe.

And, if you’re looking for a last minute treat for Halloween, these are perfect!

Ingredients for peanut butter rice crispy treats

PREP TIME: 15 minutes
COOK TIME: 15 minutes
TOTAL TIME: 30 minutes
MAKES: 1 pan of treats


3 tbsp. unsalted butter
10 oz. (1 package) of marshmallows – recommend using regular ones, may need to adjust package size if you use mini size
6 cups Rice Krispies Cereal
2 cups Reese’s Peanut Butter
1/2 cup Reese’s Peanut Butter Miniture Cups
1/2 cup Reese’s Pieces

You’ll notice I specifically say Reese’s products. They work best! I tried other peanut butter and other peanut butter cups. They just weren’t as tasty.


  1. Chop 1/2 peanut butter cups. Set aside.
  2. In large saucepan melt 3 tablespoons of butter over low heat. Add 10 ounces of marshmallows and stir until completely melted. Remove from heat.
  3. Add 2 cups of peanut butter.
    Add Kellogg’s Rice Krispies Cereal. Stir until well coated. Let cool briefly, but do not let it set.
  4. Coat a large glass pan (recommended 13 x 9 x 2 inch) with baking cooking spray.
  5. Mix in chopped peanut butter cups and half of the Reese’s Pieces. The cups may melt a bit, but that’s okay.
  6. Spray your spatula with baking spray. Press mixture into coated pan. Top with the rest of the Reese’s Pieces and any additional peanut butter cups.
  7. Let cool and then enjoy!
