And nothing is more classic than this rice krispie treats recipe! They're so easy to make, and full of gooey peanut butter flavor!

How to make peanut butter rice krispie treats
This recipe is a simplification of my fancy rice krispie treats recipe, so we're using similar ingredient amounts, but these gooey peanut butter rice krispie treats are even easier to make! All you'll need to do is heat your butter, peanut butter, and marshmallows, and stir in your cereal.
Once it's all mixed up, just press it into a greased pan and let it cool! See the recipe card below for detailed instructions!
Can I microwave peanut butter rice krispie treats?
Yes you can! I actually make this rice krispie treats recipe in the microwave most of the time when i make it! It's so easy! But if you prefer to use the stovetop, I include instructions in the recipe card below for that too!
Ingredients
- salted butter - I love the buttery flavor salted butter adds to these rice krispie treats! If you only have unsalted, just add in a couple pinches of salt.
- peanut butter - regular creamy peanut butter works fine here -- I haven't tried this recipe with crunchy peanut butter, but if you have, let me know how it worked out! As you see in the photos, I also melted a little peanut butter to drizzle on top for a burst of extra peanut butter flavor!
- marshmallows - I use a 16-ounce bag of mini marshmallows for this recipe. If you can't find mini marshmallows, regular-sized marshmallows will do just fine. And if you love marshmallows, try my Chocolate Chip and Marshmallow Cookies!
- crispy rice cereal - I usually measure mine out by weight, but you can also just measure out 10 cups worth.
Equipment
This super easy recipe doesn't require any special tools! You'll just need a 9x13 pan (or a slightly smaller pan if you want really thick treats!) -- I like this one because it comes with a lid to store your treats for later! You'll also need a bowl or saucepan to heat everything in and a wooden spoon to stir with!
Tips and F.A.Q.
If you aren't a marshmallow fan, you can swap out the marshmallows in these rice krispie treats for a sweetener like honey or maple syrup. They won't have the sticky consistency that marshmallows provide, but they'll be so delicious!
If your rice krispies are too hard, you can pop a slice of bread in the container with them to allow them to absorb some of that moisture. Or you can just place one in the microwave for a few seconds before eating to soften it up!
My favorite trick when pressing down on your rice krispie treats is to use a layer of plastic wrap and then press down with my hands. It's easier than a spatula and the plastic wrap keeps the gooey mixture from sticking to your hands!
You'll definitely want to let them cool completely. You can even place them in the fridge or freezer for a few minutes just to make sure they're fully cooled. Use a sharp knife coated in butter or sprayed with cooking spray to make sure the gooey marshmallow parts don't stick.
There's actually no need to refrigerate these rice krispie treats! You can keep them in an airtight container for up to 3 days. But I doubt they'll last that long!
Yes you can! You can freeze them in an airtight container or heavy duty freezer bag for up to six weeks. Just thaw at room temperature, and enjoy!
You've got to try my Rice Krispie Treats with Chocolate Chips for little bits of chocolatey goodness, and my M&M Rice Krispie Treats take that chocolate flavor to the next level! And for special occasions (or no occasion at all), try my Birthday Rice Krispie Treats!
