Why This Recipe Works
- They're easy to make. While we do add in some peanut butter, we don't add in any extra effort or steps. These treats are just as simple and basic to make as any other variety, and that's just one more reason to love them!
- They're flavorful. Traditional rice krispie treats are already pretty tasty, but add in the savory taste of peanut butter and we get a wonderful fluffernutter flavor in every square.
- The kids love them! You may want to double this recipe and make it in a 9x13 baking dish if you have crispy treat loving kids like I do. These squares are really hard to resist (not like you'd want to), but having extra pieces means that you can save some for later too.

🥘 Ingredients
Rice crispy cereal- This cereal is the base of the recipe, but you can feel free to use other brands of similar cereal. (I like the crispy rice cereal from Alid).
Butter- Use salted or unsalted butter to cook the marshmallows in.
Peanut butter- You will need some creamy peanut butter. I recommend not using a natural peanut butter because those tend to have more oil in the mix.
Mini marshmallows- Use mini marshmallows for that gooey texture and chewy consistency.
For the exact amounts needed, please see the recipe card below.

🔪 Instructions
Check out how to make peanut butter rice krispie treats with these simple step-by-step instructions:
Add your butter to a large pot over low heat.
Let the butter melt fully.
Add in the marshmallows.
Stir occasionally to prevent burning.
Once the marshmallows have almost completely melted, add in the peanut butter.
Stir until the marshmallows are completely melted and the peanut butter is well incorporated.
Remove the pot from the heat. Add in the cereal.
Stir to combine.
Pour the cereal into a greased 9x13 baking dish or an 8x8 baking dish if you want them thicker.
Press into the pan until they're an even layer.
Let them cool for about an hour to set before slicing into them.
Serve and enjoy.
📖 Variations
You can creamy or chunky peanut butter for these peanut butter crispies! Personally, I like the creamy peanut butter because it's what we have on hand, but if you want a little extra grit then chunky peanut butter works great.
Adding chocolate to the top-
Take a bag of chocolate chips and place them in a microwave safe bowl with 3 tablespoons of coconut oil or heavy cream. Heat for 30 seconds, stir, and then another 30 seconds, repeating until they're completely melted.
Pour over the top of the crispy bars in the baking dish and let the top harden. You can speed this process up by placing them in the freezer for a few minutes.
🍴 Recipe Tips
Making peanut butter crispy treats is pretty simple but there are a few things to note.
- Greasing your pan can be done with butter or nonstick cooking spray.
- When you press the Krispies into the pan, it really helps to have your hands greased too. This prevents it from sticking. So either rub softened butter on your hands or spray your palms with cooking spray.
- When you're melting the marshmallows, it's important to do it over a low temperature and to stir as little as possible to avoid overworking the marshmallows. It's okay to stir, but you don't need to do it constantly (except for when you melt in the peanut butter and add the cereal- that's different).
ANOTHER GREAT TIP: You can make these peanut butter rice crispy treats DAIRY FREE with the use of a plant based butter! Just double check the ingredients list on the back of the cereal box as some may contain traces of milk.
💭 FAQs
If you melt your marshmallows over too high of a heat you're cooking them too much and that will result in a much harder square when you're done. If you leave it on low, it might take a few extra minutes, but it's so much more worth it for the perfect tender treat we want.
While the two are very similar, they aren't exactly the same. Pescotcheroo bars have butterscotch chips melted into the peanut butter cereal bars for a unique flavor and there's melted chocolate on top. You can see for yourself with my Scotcheroos Recipe over here.
Absolutely! Just grab a large mixing bowl (microwave safe) and heat your butter and peanut butter for about 30 seconds until melted. Add in the marshmallows and heat for about 2 minutes, stirring at the 1 minute mark. Add in the cereal and combine. Pour into a baking dish and let set.
