What’s In Chocolate Peanut Butter Rice Krispie Treats

This recipe has all the standard ingredients you would expect in a Rice Krispie Treat, along with a few additions that take it from good to great! Here’s what you’ll need: 

  • Rice Cereal – We stick with name-brand Rice Krispie cereal, but any crispy rice cereal you have on hand is fine. You could even experiment and switch it up with a different cereal for a completely new flavor! 
  • Butter – We recommend using unsalted butter. 
  • Peanut Butter – Creamy peanut butter works best. Try to avoid natural versions as they tend to separate, and the squares won’t harden. 
  • Marshmallows & Marshmallow Fluff – This binds the cereal together and provides the sweet notes you’ll need to balance out the saltiness of the peanut butter. We recommend using mini marshmallows because they melt faster and more evenly. 
  • Cookies and Candy – Not typically found in Rice Krispie treats, the addition of peanut butter cups, Nutter Butter cookies, and Peanut M&Ms packs each bite with tons of flavor, creating an out-of-this-world sweet!

Classic Method, New Great Taste: How to Make Peanut Butter Rice Krispie Treats with Chocolate

  1. Melt. Heat the butter in a saucepan over medium-low heat. Once melted, add part of the marshmallows, and stir to melt and coat with butter. 
  2. Stir. Stir in the peanut butter, and remove the pan from the heat. 
  3. Combine. Working quickly, add the cereal, and stir to coat and combine. Add more marshmallows, and fold to combine. 
  4. Shape. Transfer half of the cereal mixture into a greased baking dish, spreading it out evenly. 
  5. Layer. Spread the marshmallow fluff evenly over the cereal mixture, and sprinkle the peanut butter cups and cookies on top. Add the rest of the cereal, and gently press in some Reese’s pieces. 
  6. Cool. Allow the mixture to cool completely. Then, slice it into squares, and enjoy!

  • Chocolate Chips – Peanut butter and chocolate are a match made in heaven. So it’s a no-brainer to add a handful of chocolate chips to your treats.
  • Peanut Butter Chips – You can never have too much peanut butter, right?! For an extra nutty flavor and a little extra texture mix in a few peanut butter chips. 
  • Sprinkles – Add tons of colors and a bit of extra crunch with your favorite sprinkles. 
  • Dried Fruit – Include your favorite fruit like strawberries, blueberries, or raisins for some added nutrients, a chewy texture, and an amazing taste! Dried varieties are best.

Common Questions About This Peanut Butter Rice Krispie Squares Recipe 

Can I use chunky peanut butter? 

We don’t recommend using chunky peanut butter because it won’t mix evenly with the marshmallows and could cause your peanut butter rice krispie squares to become crumbly. 

Can I use natural peanut butter? 

If you can avoid it, we recommend not using natural peanut butter. It tends to separate and could cause your rice krispie treats to fall apart. 

Can I use other nut butters? 

Absolutely! Feel free to use any other nut or seed butter you like best such as almond butter, sunflower butter, or tahini. 

Why are my Rice Krispie treats hard? 

The most common reason for your chocolate peanut butter Rice Krispie treats being hard is high heat. When mixing your butter and marshmallows, be sure to do so on low in order to give everything plenty of time to melt without the risk of them burning. 

Why aren’t my Rice Krispies sticking together? 

If your treats aren’t sticking together, you may need to add more marshmallows or peanut butter to the mixture. Just be sure you don’t use too much butter when melting them. An excess amount of liquid will result in loose treats! 

Can I freeze this recipe? 

Yes! Transfer the treats to an airtight container, placing a sheet of parchment paper in between each layer. Freeze for up to six months. 

Should I store leftovers in the fridge? 

Nope! These treats are best when stored at room temperature. 

How long do chocolate peanut butter rice krispie treats last? 

Stored in an airtight container, these treats will stay fresh at room temperature for up to three days or in the freezer for up to six months.
