How to make the best no bake peanut butter Rice Krispie treats. They're soft and chewy, gooey with marshmallows, and such an easy recipe to make with kids.
My middle child loves it when I make Rice Krispie treats. Add a little peanut butter in, making them peanut butter rice crispy treats, and he's in heaven.
My favorite thing about this recipe is that you only need 6 ingredients to make it. And there's no baking involved, just a little bit of stove time.
I prefer to use creamy peanut butter to make these peanut butter Rice Krispie bars, but you can use crunchy too.
Other than the peanut butter, though, this recipe is very similar to our favorite Rice Krispie treats recipe, as well as microwave rice crispy treats.

WHAT KIND OF MARSHMALLOWS SHOULD YOU USE TO MAKE PEANUT BUTTER MARSHMALLOW RICE KRISPIE TREATS?
While you can use either big marshmallows or mini marshmallows, I definitely recommend using the minis. You can also use marshmallow fluff, although I’ve never tried it with this particular recipe.
You do have to melt the marshmallows before mixing everything together with the Rice Krispies cereal. Because of this, the mini marshmallows are an easier choice, as they melt a lot quicker than the jumbo marshmallows.
HOW TO MAKE PEANUT BUTTER RICE KRISPIE TREATS
You can use pretty much any crispy rice cereal for this peanut butter Rice Krispie squares recipe, whether you choose to use the original Rice Krispies cereal, a generic brand, or a store brand.
Quick Tip: Make sure you use salted butter over margarine. Butter will give your marshmallow treats a richer flavor and texture.
Before you get started, prepare your baking dish by generously spraying it with cooking spray.
Making marshmallow treats is a quick 4 step process…
- Melt the butter in a large sauce pan or Dutch oven on the stovetop.
- Then add in the vanilla extract, salt, and mini marshmallows.
- Continue to heat and stir the mixture until the marshmallows have completely melted; then remove from heat, and stir in the peanut butter.
- Once the peanut butter is melted and fully stirred into the marshmallow mixture, stir in the Rice Krispies.
Finally, just spread the peanut butter Rice Krispie treats into a greased baking dish and let them cool.
CREATIVE IDEAS FOR THESE PEANUT BUTTER TREATS
Chocolate and peanut butter pretty much go hand in hand, so here are a few ideas with ways to dress up your homemade treats.
- Top your peanut butter Rice Krispie treats with chocolate topping, using melted chocolate.
- Drizzle the treats with melted white chocolate.
- Mix things in… For instance, make peanut butter Rice Krispie treats with chocolate chips, Reese's Pieces, peanut butter cups, M&M's, etc.
- Mix peanuts or other favorite kinds of nuts into the mixture for a sweet and salty flavor.

HOW TO KEEP RICE KRISPIE TREATS SOFT
Unfortunately, Rice Krispie treats are one of those desserts that after 2 or 3 days will start to harden up and be either extra chewy or rock solid.
Two ways to keep them soft are by using fresh ingredients, especially the marshmallows and cereal, and by cooking the marshmallow mixture on low to medium heat.
Also, use lots of marshmallows. If you're using 6 cups of cereal (as in the case with this recipe), you'll want the same amount of marshmallows, so a 1:1 ratio.
And finally, another way to keep them soft is to store them properly, which brings me to my next point.
HOW TO STORE RICE KRISPIE TREATS
Be sure to store any leftover treats in an airtight container or sealed plastic bag.
And as I mentioned, you'll probably want to eat them within the first 2 or 3 days.
CAN YOU FREEZE RICE KRISPIE TREATS?
You can if you need to. And then get them out with at least half an hour to thaw before serving.
Be sure when freezing them, though, that you store them in an airtight container or freezer bag. And you might even put wax paper or parchment paper between the layers of treats so they don't stick together.

I made these and made homemade peanut butter frosting for the top of them …. And they are wonderful 🥰
Trina, that sounds delicious! I bet these would go great with peanut butter frosting.
I’ve always put PB in with butter an marshmallows.. seems to mix better an get all on Krispies… An I use JIF PB … YUMYUMFERMYTUMTUM!!!
That sounds delicious, Dolores! Thanks for sharing.
I make these all the time. I use three cups of rice krispie and three cups of cocoa pebbles and they are a huge hit with the family and partys. I would like to know how much of the big marshmallows to use. I only used the little ones.
Harper, I’ve always used minis, so I can’t say for sure how much to substitute, but my recommendation would be to weigh out 6 cups of mini marshmallows, and match that weight with the big marshmallows. This would be more accurate than matching volume. The weight is also usually specified on the bag. For example, it may say on the bag that 1 cup of marshmallows, big and small, weighs X amount. With some quick math, you can easily figure up how many more of the big marshmallows you should use to match that weight. I hope this helps!
Just made these. I added a cup of chocolate chips with the peanut butter and if my taste test (AKA licking the spoon) is any indication, they are yummy! I doubt they will last long. Thanks for posting the recipe!
Thank You for the kind review, Susie!
