Cook Peanut Butter Cup Rice Krispie Treats Like This

Now that we have everything set up, let’s jump into the steps for making these delightful Peanut Butter Cup Rice Krispie Treats!
Step 1: Melt the Butter and Marshmallows
In a medium saucepan over low heat, melt the 1 cup of unsalted butter until it’s completely liquefied. Next, add in 1 package of mini-marshmallows (10 ounces) and stir continuously until the marshmallows are completely melted and smooth. This process should take about 5 minutes.
Step 2: Mix in Peanut Butter and Flavorings
Once the marshmallows are melted, remove the saucepan from the heat. Add in 1 cup of creamy peanut butter, a pinch of sea salt, and 1 teaspoon of pure vanilla extract. Stir until everything is well combined and glossy.
Step 3: Combine the Cereals
In your large mixing bowl, combine 5 cups of Cocoa Krispies cereal and 5 cups of Cap’n Crunch’s Peanut Butter Crunch cereal. Pour the melted marshmallow mixture over the cereals and mix well. Ensure every piece of cereal is coated with that luscious mixture.
Step 4: Add the Chocolate Chips and Reese’s
Gently fold in 1 cup of semi-sweet or dark chocolate chips, 1 cup of Reese’s peanut butter baking chips, and the entire bag of Reese’s Minis Unwrapped. This step adds layers of flavor and texture to your treats.
Step 5: Set the Mixture in the Pan
Transfer the cereal mixture into the prepared 9×13 inch baking pan. Use your rubber spatula to press the mixture evenly into the pan. Make sure it’s compacted well to hold together when cut.
Step 6: Let it Cool and Cut
Allow the treats to cool completely at room temperature, which should take about 30 minutes. Once cooled, cut into squares or rectangles with a sharp knife.
If You’re Out Of…

If you find yourself short on some ingredients, here are some substitutes:
- Unsalted Butter: You can use salted butter, but omit the pinch of sea salt.
- Cocoa Krispies: Any chocolate cereal can work in a pinch.
- Cap’n Crunch’s Peanut Butter Crunch: Use another nut-based cereal or any crunchy cereal you enjoy.
- Chocolate Chips: Use milk chocolate or white chocolate chips as an alternative.
Mistakes That Ruin Peanut Butter Cup Rice Krispie Treats
Creating these Peanut Butter Cup Rice Krispie Treats is simple, but there are a few common mistakes to avoid:
- Not melting the marshmallows enough: Make sure they are fully melted for the right texture.
- Overpacking the treats in the pan: While you want them to hold together, pressing too hard can make them dense and tough.
- Using stale cereals: Fresh cereals will provide the best crunch and flavor.
- Skipping the salt: A pinch of salt enhances the flavors and balances the sweetness.
How to Store & Reheat
To keep your Peanut Butter Cup Rice Krispie Treats fresh, follow these guidelines:
- Store in an airtight container at room temperature for up to one week.
- For longer storage, you can freeze them. Wrap individual pieces in plastic wrap and place in a freezer-safe bag. They’ll last for up to three months.
- To reheat, simply microwave for 10-15 seconds to soften slightly before enjoying.
