Step‑by‑Step Instructions for Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats
Step 1: Prepare the Pan
Begin by lining an 8×8 inch square baking pan with parchment paper, ensuring it hangs over the edges for easy removal. Alternatively, spray the pan with nonstick cooking spray to prevent sticking. Set the prepared pan aside while you whip up the delicious Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats.
Step 2: Melt Butter and Marshmallows
In a large pot set over medium-low heat, add in the salted butter and let it melt completely. Once melted, stir in 1.5 bags of mini marshmallows, creamy peanut butter, and a pinch of sea salt. Continuously stir the mixture for about 4-5 minutes or until everything is melted and well combined into a smooth, gooey base.
Step 3: Combine Rice Krispies
Remove the pot from heat and carefully fold in the Rice Krispies cereal, allowing each piece to get coated in the melty mixture. Next, add the vanilla extract and the remaining half bag of mini marshmallows into the pot, stirring until everything is evenly mixed. The result should be a sticky, delightful base for your Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats.
Step 4: Layer the Mixture
Press half of the Rice Krispies mixture firmly yet gently into the bottom of the prepared pan. Make sure it’s even. Now, take the whole Reese’s peanut butter cups and place them side by side on top of the base layer. Carefully spread the remaining Rice Krispies mixture over the Reese’s cups and press gently, sealing them within.
Step 5: Add Topping
Sprinkle the chopped Reese’s Peanut Butter Cups evenly over the top of the final layer. This will provide additional crunchy peanut flavor that enhances the treat. Ensure each piece is distributed well for maximum delight in every bite of your finished Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats.
Step 6: Make Chocolate Drizzle
In a microwave-safe bowl, combine the semi-sweet chocolate chips, creamy peanut butter, and a little salted butter. Microwave in 30-second intervals, stirring between each, until the mixture is completely melted and smooth, which should take about 1-2 minutes. This rich drizzle will be the finishing touch to your treats.
Step 7: Drizzle and Chill
Once your chocolate mixture is ready, drizzle it enthusiastically over the top of the Rice Krispie layer, ensuring even coverage. Afterward, place the pan in the refrigerator to chill for at least 30 minutes or leave it at room temperature for 1-2 hours until set. Once firm, cut into squares to serve your scrumptious Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats!

Expert Tips for Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats
- Fresh Marshmallows: Ensure you’re using fresh mini marshmallows for the best melt and texture; stale marshmallows can lead to clumps.
- Gentle Pressure: When layering the Rice Krispies mixture in the pan, press gently to maintain a chewy texture; overpacking may make them too hard.
- Chill Properly: Allow enough chilling time after drizzling chocolate; this helps set the treats properly without losing their dreamy texture.
- Salt Balance: If you’re adding sea salt on top, sprinkle lightly; too much salt can overpower the sweetness of the Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats.
- Drizzle Creativity: Experiment with different kinds of chocolate for the drizzle, or even add a splash of peanut butter for a richer flavor layer!

Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats Recipe FAQs
How do I select the best ingredients for my Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats?
Absolutely! When choosing ingredients, opt for fresh mini marshmallows—stale ones won’t melt well. Look for salted butter for the best flavor but you can go for unsalted if you prefer less salt. For the creamy peanut butter, avoid all-natural varieties as they can be too thick, making it difficult to achieve that perfect gooey texture. As for vanilla extract, pure vanilla adds the most flavor, enhancing the overall taste of your treats.
What’s the best way to store leftover treats?
Perfectly! Store your Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats in an airtight container at room temperature for up to 4 days to keep them deliciously chewy. If you place them in the fridge, they may harden a bit, but they’ll stay fresh for about a week when loosely covered. Just remember, for the ultimate chewy experience, room temperature is the way to go!
Can I freeze these Rice Krispie treats?
Of course! To freeze your Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats, wrap them tightly in plastic wrap or place them in an airtight container. They can last in the freezer for up to 2 months. When you’re ready to enjoy them, simply thaw them at room temperature for about 30-60 minutes. If you prefer a softer treat, you can gently microwave individual pieces for a few seconds!
What should I do if my Rice Krispie mixture is too dry?
Ah, the classic troubleshooting tip! If you find your mixture is too dry, it might be because you didn’t use enough marshmallows or butter. To fix this, warm up a bit more butter and marshmallows (1 tablespoon of each) over low heat until just melted, then mix it into your Rice Krispie mixture until it reaches a gooey consistency. Stir well, and your treats will become perfectly delightful again!
Can these treats be made allergen-friendly?
Very much so! If you’re looking to make allergen-friendly Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats, consider swapping out regular butter for dairy-free alternatives and using allergen-free chocolate chips. For nut allergies, use sunbutter or soy nut butter in place of peanut butter. Just check ingredient labels to make sure everything fits your dietary needs!
