The Best Peanut Butter Rice Crispy Treats

My whole family loves Rice Krispie Treats and my husband loves peanut butter, so I decided to combine the two. Cereal treats have the best texture and the addition of peanut butter makes them have the best flavor.

These snacks are so easy to make and they use simple ingredients. Kids love them, but you’re never too old to make a perfect rice crispy treats. We love them thick and soft and chewy – these are the perfect cereal treats!

Ingredients Needed

  • Rice Krispie Treats: You can find this cereal at just about any grocery store. Any brand crispy rice cereal works.
  • Peanut Butter: These have only been tested with shelf stable peanut butter, like Skippy or Jif. I don’t recommend natural peanut butter.
  • Marshmallows: Mini marshmallows melt easiest, but large are fine too.

Variations

  • Feel free to substitute shelf stable cashew butter, almond butter, or any nut butter you like.
  • You can make these with gluten-free cereal.
  • Use cocoa pebbles to make chocolate peanut butter Rice Krispie treats!
  • Stir a cup or two of chocolate chips into the cereal marshmallow mixture.

How to make Rice Krispie Treats

  • Melt the butter in a large saucepan over medium low heat. Add the peanut butter and stir until combined. Add the marshmallows and stir until melted. Remove from heat and stir in vanilla extract.
  • Add cereal and stir to coat with the marshmallow mixture.
  • Immediately pour into baking dish and press firmly to compact into an even layer.

Expert Tips

  • Make sure your marshmallows are fresh! Stale marshmallows will effect how the entire recipe tastes. It is also important to make sure your cereal is fresh too!
  • To press the mixture more easily, spray wax paper with nonstick cooking spray so you can press without it sticking to your hands.
  • Store properly to make sure they stay fresh.
  • You can also melt everything in a microwave-safe bowl instead of doing it on the stove.

Storage

Store in an airtight container for several days. You can also freeze Rice Krispie treats between sheets of wax paper.
