Rice Krispie Treats are a classic from my childhood and there is nothing I love making more, probably because they are so dang easy to make! Throw together a few ingredients and you have a delicious treat in less than 1 hour.

Peanut Butter Rice Krispie Treats are a little twist on the classic recipe. Adding creamy peanut butter makes these even more irresistible. These are seriously so good!

My other favorite rice krispie recipe is my Brown Butter Rice Krispie Treats! If you're looking for more peanut butter recipes, my peanut butter pie is my go-to fav, as well as my small-batch peanut butter cookies!

Why You'll Love Peanut Butter Rice Krispie Treats

• You only need 6 ingredients.
• They take about 10 minutes to make and they cool down quickly, so they'll be ready in under an hour!
• You can add a chocolate or peanut butter drizzle on top which makes them even better.
• You don't have to turn on your oven to make them.
• They're fun to make with kids!

Ingredients Needed

Here are some notes on a few ingredients- please see the full ingredient list in the recipe card below!

• peanut butter- creamy peanut butter is my fav! I didn't test this with natural peanut butter but it should work fine.
• marshmallows- mini marshmallows work best in this recipe but you can use big ones if that's all you have. The mini ones are great for reserving a cup and adding them in at the end for pockets of gooey marshmallows.
• rice krispie cereal- obviously needed to make peanut butter rice krispie bars! I used regular rice krispie cereal but I have suggestions for substitutions below.
  

Step by Step Instructions

Step 1: In a large pot or dutch oven, melt together the butter and peanut butter on medium heat until completely smooth and combined.

Step 2: Turn the heat to low and add in the marshmallows, reserving 1 cup for later use. Mix until the marshmallows have melted and then immediately remove from the heat.

Step 3: Pour in the rice krispies and mix until just coated, then add in the extra cup of marshmallows. Mix until all the cereal is coated and press into a baking dish using a silicone spatula (helps it to not stick). Allow them to cool before cutting into bars 

How to Make Rice Krispie Treats in the Microwave:

Step 1: Melt the butter and peanut butter in the microwave in a large microwave-safe bowl. Microwave in 1-minute intervals on medium power, stirring in between until smooth and melted.

Step 2: Add in the vanilla and salt, mixing to combine.

Step 3: Pour in the marshmallows and put them back into the microwave at 1-minute intervals until melted and smooth (mixing in between).

Step 4: Pour in the cereal and coat evenly, then press it into the pan and allow it to cool.

Add-in & Topping Ideas:

Other ideas to add to your peanut butter rice crispy treats:

• Different cereal- You can use any brand of rice cereal or totally change it up. Some good cereals that come to mind and would pair well with peanut butter are cocoa krispies and golden grahams!
• Chocolate drizzle- this would also be a great idea! Just melt some chocolate in the microwave and drizzle over the top of your cooled treats. Chocolate peanut butter rice krispie treats sounds amazing to me!
• Chocolate chips- this is obvious because what's better than chocolate and peanut butter? I would add about 1 cup of chocolate chips to the mixture. It might melt a little since the marshmallow mixture will be warm but it's ok.
• Chopped candy- Reese's Cups in these? Sign up me. You could also do Reese's Pieces, Snickers, Twix, Butterfingers! Basically, anything would be delicious- I would use 1 cup of any add-in.
• Sprinkles- because sprinkles legit make everything better!

Storing & Freezing

Store these rice krispie peanut butter treats in an airtight container at room temperature. They are most fresh/soft 2-3 days after making but are fine to eat after that time. I do not recommend storing these in the fridge as it makes them very hard!

They can also be frozen for up to 2 months in an airtight container. I recommend putting wax or parchment paper between the layers before freezing.
