Loaded Peanut Butter Rice Krispie Treats Ingredients

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 rice crisp cereal you have on hand is fine. You could even experiment and switch it up with a different cereal for a little added taste and texture! 
  • Butter – We recommend unsalted butter for these peanut butter rice Krispie treats. There is already plenty of salt from the peanut butter! 
  • Peanut Butter – Feel free to use your favorite brand of peanut butter for these. However, we do recommend sticking with the creamy version.
  • 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. 
  • Cookies & 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!

Optional Add-Ins and Flavor Variations

  • 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 amazing taste! 
  • Chopped Nuts – Capitalize on the salty flavor we all love by adding in a handful of your favorite chopped nuts!

Frequently Asked Questions

Why are my Peanut Butter Rice Krispie Treats so hard? 

The most common reason for your 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 risking them burning. 

What do I do if my Rice Krispie Treats aren’t sticking together? 

If your treats aren’t sticking together, you may need to add more marshmallows 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! 

How long do these treats stay fresh? 

You can store your peanut butter rice Krispie treats in an airtight container for up to 2 days at room temperature. Or, if you want to keep them longer, store them in the freezer for up to 6 weeks.
