What ingredients go into Peanut Butter Rice Krispie Treats?

ingredients for making Peanut Butter Rice Krispie Treats
  • Butter: I used salted Irish butter, but use whatever you have on hand. I had a brain fart and totally forgot to include butter in the image below. <shrug>
  • Peanut butter: Regular, creamy Jif peanut butter. I haven't tested this recipe with a natural peanut butter, but if you go this route, I'd recommend really stirring it up so that the oil is well combined into the peanut butter.
  • Marshmallows: I find that mini marshmallows work best, and melt most easily. But you can definitely use the big fat ones, too.
  • Vanilla extract: Store bought or homemade vanilla extract will work.
  • Sea salt: I added a pinch of flaky sea salt to balance out the sweetness from the marshmallows.
  • Rice Krispies cereal: Buy a big box!
  • Peanut butter chips: Adding these is optional, but I really liked having little pockets of peanut butter chips throughout these rice krispie treats.

How to make Peanut Butter Rice Krispie Treats

Start out by browning your butter! It's easy to do and adds so much nutty, delicious flavor. Just make sure to keep an eye on it, as it can go from brown and delicious to burned and inedible in no time flat.

Next, peanut butter and marshmallows enter the pot. It takes a bit of stirring to get all of the marshmallows to melt and incorporate, but soon you'll have a pretty homogenous mixture. Salt and vanilla extract provide some more flavor.

Rice Krispies cereal, some more mini marshmallows (they create pockets of marshmallowy goodness throughout!), and peanut butter chips are added last. Everything gets stirred up until all of the cereal is coated in the peanut butter/marshmallow mixture and the marshmallows and PB chips are distributed throughout.

Your peanut butter rice krispie treats will then get pressed into a baking dish and cool down and solidify a bit before being ready for eating!

All in all, easy peasy. If you have kids (nieces/nephews/grandkids/etc.) and want to get them involved, this would be a great recipe for that.

This Peanut Butter Marshmallow Pie with Pretzel Crust and this Almost No-Bake Chocolate Peanut Butter Pie also merit mentioning because they are both almost no-bake. For both of these recipes, all you need to do is pop the crust in the oven for a bit. The rest of the pie requires zero baking.

Frequently Asked Questions

How much peanut butter to add to rice krispie treats?

For a recipe of this size, one cup will do it!

What kind of peanut butter should I use?

I used regular old creamy Jif. I haven't tested this recipe with a natural peanut butter, but I don't see why it wouldn't work. Just make sure to really stir it up so that the oil gets incorporated well.

How long will these rice krispie treats keep?

These are best if stored in an airtight container and if consumed within a couple of days. They tend to start getting hard after that (they still taste good, though!).

Why are my peanut butter rice krispie treats hard?

There could be a couple of things at play here. Did you store them in an airtight container and eat them within a couple of days? If no, then that might be the reason they're hard. Alternately, you want to make sure that you melt your butter, marshmallows, and peanut butter on low heat. Using high heat can result in hard rice krispie treats.

Can I add chocolate or other mix-ins?

Sure! Toss some chocolate chips in there, or maybe drizzle or dip these treats in some chocolate. It's all good.

Can I use a different cereal?

Yes! Mix it up, if you want! You could use Cocoa Krispies, for instance. I also have a recipe for Lucky Charms Cereal Bars that you should check out for inspo.

Ingredients
  

  • 8 tablespoon butter
  • 1 cup peanut butter
  • 20 oz mini marshmallows reserving 1 cup
  • 1 teaspoon vanilla extract
  • 1 teaspoon flaky sea salt
  • 9 cups puffed rice cereal e.g., Rice Krispies
  • 1 cup peanut butter chips

Instructions
 

  • Line a 9x13-inch pan with parchment paper, allowing some to hang over on the sides. Set aside.
  • In a heavy bottomed pot over medium heat, melt the butter. Stir the butter the entire time. Once it has melted, the butter will foam and sizzle around the edges a bit.
  • Continue to stir the butter. The butter will turn a golden brown color. Some of the foam will have subsided and the milk solids at the bottom of the pan will be a toasty brown. It will smell very buttery and nutty.
  • Once it reaches this state, immediately add the peanut butter and stir to combine.
  • Add the marshmallows and stir until everything is well combined. Add the vanilla extract and flaky sea salt.
  • Turn off the heat and the rice cereal to the pot. Stir until all of the cereal has been coated in the peanut butter and marshmallow mixture.
  • Add the reserved marshmallows and the peanut butter chips. Stir until they are evenly distributed throughout the cereal.
  • Pour the cereal mixture into the prepared pan. Lightly press it down in an even layer.
  • Allow the treats to cool for about an hour before slicing and eating.
