What Ingredients You Need to Make Rice Krispie Treats with Peanut Butter

There are only 4 ingredients needed to make the most fun-tastic peanut butter Rice Krispie treats recipe at home:

That’s it!

I use mini marshmallows to make my peanut butter Rice Krispie treats recipe because they are the easiest to melt. However, you can also use large marshmallows or even marshmallow cream if you like.

If you do use large marshmallows, I suggest that you first snip them in half with kitchen scissors or a knife to help them melt faster. 

For handy conversion:

  • 1 cup of mini marshmallows is equal to 8 large ones.
  • One 7 oz jar of marshmallow cream is equal to 1 1/2 cups mini marshmallows.

  1. First, prepare a large 9×13 inch pan by spraying with nonstick spray or greasing with butter.

  3. Once combined turn the heat down to low and add the mini marshmallow to the pot. Stir until the marshmallows have just melted, making sure to not overcook. Pour in the Rice Krispies and use a spatula to gently stir and fold until the cereal is completely coated in the melted peanut butter and marshmallow mixture.
  4. Transfer the coated cereal to your prepared pan, and lightly press to make an even layer.

Let the treats cool at room temperature before slicing with a sharp knife.

Tips for Making the Best Rice Krispie Treats With Peanut Butter

Wondering how to make peanut butter Rice Krispie treats that are soft, gooey, and slightly crunchy? Here are a couple of key tricks to note for creating foolproof Rice Krispie treats every time…

  • For the tastiest squares be sure you use fresh marshmallows that have not gone stale, and do not overcook them when melting. Cooking them too long will cause the Rice Krispie treats with peanut butter to be extra dense and hard.
  • Along with greasing your pan, it helps to add a layer of parchment paper to the bottom. Then the treats can be more easily lifted out before they are cut.
  • Spray your fingers lightly with nonstick spray or dip them in water before lightly smooshing the treats into the pan. This will help keep the peanut butter Rice Krispie mixture from sticking to your hands.
  • Rice Krispie treats with peanut butter taste best when eaten fresh the same day. But they can be stored in an airtight container or wrapped in plastic wrap and kept at room temperature for another 2-3 days.
