Step‑by‑Step Instructions for Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats
Step 1: Prepare Your Pan
Start by lining an 8×8 inch baking pan with parchment paper for easy removal or lightly spray it with cooking spray. This step ensures your Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats will come out cleanly once they’re set. Set the pan aside while you prepare the rest of the ingredients.
Step 2: Melt the Butter
In a large pot over medium-low heat, melt 1/2 cup of salted butter. Stir frequently to prevent it from browning. Once completely melted and bubbly, this will form the base of your delicious peanut butter mixture. Patience is key here; it usually takes about 3-5 minutes for the butter to melt nicely.
Step 3: Combine Ingredients
After the butter is melted, add 1.5 bags of mini marshmallows, 1 cup of creamy peanut butter, and a pinch of sea salt into the pot. Stir continuously for about 5 minutes until the marshmallows become gooey and fully melted. You want a smooth, cohesive mixture, but be careful not to overheat it; the marshmallows should retain some shape.
Step 4: Mix in Rice Krispies
Remove the pot from the heat and add 6 cups of Rice Krispies and 1 teaspoon of vanilla extract, mixing thoroughly. This step brings texture to your treats while ensuring every crispy piece gets well coated with the peanut butter mixture. The mini marshmallows should remain somewhat intact for added chewiness.
Step 5: Press the First Layer
Take half of the Rice Krispie mixture and press it firmly into the prepared pan. Use your hands or a spatula to flatten it evenly, creating a solid base without packing it too tightly. This will help achieve that light, chewy texture necessary for the perfect Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats.
Step 6: Add the Reese’s Cups
Evenly space 9 regular-sized Reese’s peanut butter cups over the pressed Rice Krispie layer. Gently press them down to ensure they create a decadent filling while still being visible. This mid-layer adds an irresistible creaminess that’s hard to resist in your treats.
Step 7: Top with Remaining Mixture
Next, take the remaining Rice Krispie mixture and press it over the Reese’s cups, covering them completely. Be gentle during this step; too much pressure may compact your treats. You want to ensure they hold their shape without losing their delightful texture.
Step 8: Prepare the Topping
Sprinkle chopped Reese’s peanut butter cups over the top layer for a delicious crunch and added flavor. This finishing touch will create a beautiful presentation and an extra burst of peanut butter goodness in every bite.
Step 9: Melt the Chocolate Drizzle
In a microwave-safe bowl, combine 1 cup of semi-sweet chocolate chips, 2 tablespoons of peanut butter, and 1 tablespoon of butter. Microwave this mixture for about 2 minutes, stirring every 30 seconds, until it’s fully melted and smooth. This rich chocolate drizzle is the perfect finishing touch for your Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats.
Step 10: Drizzle and Set
Carefully drizzle the melted chocolate mixture over the top of your treats. Allow them to chill in the refrigerator for at least 30 minutes or let them set at room temperature for 1-2 hours. This step is essential to let the chocolate harden and for the treats to firm up, making cutting them into squares much easier.

Expert Tips for Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats
-
Use Fresh Marshmallows: Ensure your mini marshmallows are fresh for the best gooey texture; stale marshmallows won’t melt properly.
-
Gentle Pressing: When layering the Rice Krispie mixture, press down gently. Over-compressing can lead to dense, hard treats rather than the desired light and chewy texture.
-
Chill for Firmness: Don’t skip the chilling step! Allowing your Reese’s Peanut Butter Cup Stuffed Rice Krispie Treats to set properly will make them easier to cut and enhance the flavor.
-
Customize Your Drizzle: Feel free to swap semi-sweet chocolate chips for milk or white chocolate for a fun twist. You can even sprinkle crushed cookies on top for added texture.
-
Use Parchment Paper: Line your baking pan with parchment paper for a hassle-free release after they’ve set. This step saves time and keeps your treats intact!

You can prepare the Rice Krispie base up to 24 hours in advance; simply follow the first six steps, press the mixture into the pan, and refrigerate.

When you’re ready to finish, simply layer the cups and drizzle the melted chocolate over the top before letting them set. This prep method ensures that your treats maintain their delightful texture and flavor, making them just as delicious as if they were freshly made.
