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.

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…

  1. Melt the butter in a large sauce pan or Dutch oven on the stovetop.
  2. Then add in the vanilla extract, salt, and mini marshmallows.
  3. Continue to heat and stir the mixture until the marshmallows have completely melted; then remove from heat, and stir in the peanut butter.
  4. Once the peanut butter is melted and fully stirred into the marshmallow mixture, stir in the Rice Krispies.

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.

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.
