Tips & Variations
- Use crunchy peanut butter for added texture if you prefer a bit of bite in the treats.
- For a nut-free version, substitute the peanut butter cups with chocolate caramel cups or simply omit and add extra marshmallows.
- To make cutting easier, chill the treats for about 30 minutes before slicing.
Storage
Store the treats in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to one week. If refrigerated, allow them to come to room temperature before serving for the best texture. These treats do not require reheating.

FAQs
Can I use regular marshmallows instead of mini marshmallows?
Yes, regular marshmallows will work fine. You might need to cut them into smaller pieces for easier melting and mixing.
What if I don’t have heavy whipping cream for the chocolate topping?
You can substitute with an equal amount of whole milk or half-and-half, but the topping may be slightly less rich and creamy.

- 24 Reese’s Peanut Butter Cups, unwrapped
Chocolate Ganache Topping
- 2 cups chocolate chips
- ½ cup heavy whipping cream
Instructions
- Prepare the Pan: Butter or spray a 9×13-inch pan to ensure the Rice Krispie mixture doesn’t stick, then set it aside.
- Melt Butter and Marshmallows: In a saucepan over low heat, melt the unsalted butter. Add the mini marshmallows and stir continuously until they are completely melted and smooth. Stir in the creamy peanut butter until well combined.
- Mix in Cereal: Pour the plain Rice Krispies cereal into the marshmallow mixture. Stir thoroughly until every piece is coated with the marshmallow-peanut butter mixture.
- Layer Half the Mixture: Quickly press half of the Rice Krispie mixture into the prepared pan in an even layer, working fast before the mixture sets.

- Top with Remaining Mixture: Spoon the remaining Rice Krispie mixture over the peanut butter cups. Press down firmly to seal the layers together, then allow the entire treat to cool completely.
- Make Chocolate Ganache: In a saucepan over low to medium heat, combine the chocolate chips and heavy whipping cream. Heat gently, stirring constantly until the chocolate is melted and the mixture is creamy and smooth.
- Decorate and Set: Spread the warm chocolate ganache evenly over the top of the cooled Rice Krispie treats. Let it set until firm.
- Serve: Once set, cut into 24 squares. Store the treats in a sealed container at room temperature to maintain freshness.
Notes
- Work quickly when pressing the Rice Krispie mixture into the pan as it hardens as it cools.
- If peanut allergies are a concern, substitute peanut butter and peanut butter cups with a safe alternative like almond butter and chocolate candies without peanuts.
- For easier spreading, slightly warm the chocolate ganache if it firms up before spreading.
- Store treats at room temperature up to 3 days or refrigerate for longer freshness; let them come to room temperature before serving for best texture.
- Use gloves or buttered hands to press the mixture into the pan to prevent sticking.
