Why You’ll Love These Peanut Butter Rice Krispie Treats

Who doesn’t love a good rice krispie treat? I mean, they are buttery, sweet, chewy, and delicious. Plus so easy to make! But we all know any dessert is better when you add peanut butter and chocolate. I mean, I’m pretty much obsessed with this combo, so I had to add it to my marshamllowy treats. Here’s why you’ll crave them too…

  • Gluten Free. Missing traditional rice krispie treats? I know how you feel! But, making gluten free rice krispies treats is possible, and they taste just as good as the regular version. Use gluten free cereal to easily make this recipe gluten free.
  • No-Bake. I truly love a no-bake dessert and rice krispie treats peanut butter is a winner. It’s great for a last-minute after-school sweet treat or to serve at birthday parties. And you can adjust the ingredients if needed to accommodate any food allergies (see tips lower down).
  • Keeps well. These bars keep great at room temperature for up to 1 week, although I’m not saying you won’t eat them all in a few days!

What You’ll Need

See the ingredients in these chocolate peanut butter rice krispie treats plus some notes below. Don’t forget to check the recipe card at the end of this post for the full ingredient amounts.

  • Butter: For these treats, you’ll use salted butter to add a little salt to balance the sweetness of the marshmallows. If you don’t have salted butter, use unsalted butter and add ¼ teaspoon salt.
  • Peanut Butter: Use creamy peanut butter rather than crunchy. You can use conventional or natural peanut butter, just make sure that it is well stirred.
  • Marshmallows: I use mini marshmallows but if needed you can use regular marshmallows. You’ll need 16 ounces of whatever size of marshmallow you choose (and yes, marshmallows are gluten free!).
  • Vanilla Extract
  • Crispy Rice Cereal: Use a gluten free brand of cereal – you read more about what cereals are gluten free in this post. Note that Kellogg’s Rice Krispies are not gluten free.
  • Chocolate: I use semisweet chocolate chips or you can use chopped chocolate.
  • Oil: Avocado or vegetable oil is used to help the melted chocolate become smooth and spreadable.

How To Make Chocolate Peanut Butter Rice Krispie Treats

This easy no-bake recipe takes minimal effort and is perfectly salty-sweet! You can see how to make it in the photos below. Find the detailed instructions in the recipe card lower down.

  • Prepare. Line a 9×9-inch square baking pan with parchment paper and grease it.
  • Melt butter and peanut butter. Over low heat, melt the butter and peanut butter together, then add all but 1 cup of the marshmallows.
  • Melt the marshmallows. Mix over low heat. Keep stirring until the mixture is smooth.
  • Add vanilla. Pour in the vanilla, stirring gently to combine.
  • Add cereal. Now fold in the cereal and reserved marshmallows.
  • Place in pan. Gently press the cereal mixture into the prepared pan.
  • Melt the chocolate. Place the chocolate in a microwave-safe bowl and microwave it until nearly melted, then add the coconut oil.
  • Add to bars. Spread the chocolate evenly over the pan with the cereal mixture.
  • Cool. Let cool at room temperature until firm.

Tips for Success

Rice krispies treats are one of those classic easy desserts that anyone can make!

To help you make this recipe even more easily, follow these tips:

  • Make clean cuts. These treats are thick. I’ve found that a brisket knife works best for cutting them into neat, clean squares because they are long and sharp with a flat edge.
  • Brush with oil. If your chocolate has a dull or whitish finish when it hardens, you can lightly brush it with a very small amount of avocado oil or vegetable oil (I like to use the kind that comes in an aerosol can).
  • Make in a larger pan. If you wish, you can make these peanut butter rice krispies treats in a 13×9-inch pan. Note that the treats and chocolate layer will be thinner if you press them into a larger pan. You may want to use 1 1⁄2 cups of chocolate chips and 1 1⁄2-2 teaspoons oil for the topping if you use a larger pan.
  • Skip the chocolate. Like just peanut butter without any extra chocolate? You can skip the chocolate layer.
  • Use another nut butter. Try almond butter instead of peanut butter, or another nut butter of choice. If you can’t have nuts, substitute sunflower seed butter for the peanut butter.
  • Make it dairy-free. If you want to make this recipe dairy-free, substitute your favorite non-dairy butter for the butter (make sure it’s salted as this helps keep the treats stay fresh longer), and vegan chocolate.

Proper Storage

Store these gluten free peanut butter rice krispies treats in an airtight container or zip-top bag at room temperature for up to 7 days. If you plan to pack these in lunchboxes, wrap each treat in plastic wrap.

Prep: 10 minutes
Cook: 10 minutes
Cooling time 2 hours
Servings: 16 servings

Ingredients

  • 4 tablespoons salted butter , OR 4 tablespoons unsalted butter plus ¼ teaspoon salt
  • ½ cup creamy peanut butter
  • 8 cups (16 ounces) mini marshmallows (preferably Kraft Jet Puffed), divided
  • 1 teaspoon pure vanilla extract
  • 6 cups Crispy Rice Cereal (Be sure to use a brand that is gluten free. Kellogg’s Rice Krispies are NOT gluten free.)
  • 1 cup semisweet chocolate chips, or 8 oz. chopped chocolate
  • 1 teaspoon avocado or vegetable oil

Instructions

  • Line a 9×9-inch square baking pan with parchment paper or aluminum foil and grease it generously with cooking spray or butter.
  • In a large, heavy-bottomed saucepan or Dutch oven, melt the butter and peanut butter over low heat. Set aside 1 cup of the marshmallows, and add the remaining 7 cups to the melted butter. Stir over low to medium-low heat until just melted (it’s fine if a few unmelted marshmallows remain). Remove from the heat and stir in the vanilla extract (plus the salt if you use unsalted butter).
  • Add the cereal and reserved 1 cup of marshmallows and gently stir with a spatula until the cereal is evenly coated.
  • Transfer the mixture to the prepared baking dish and gently press down with your fingers to spread it out and fill the pan, but do not pack it down tightly.
  • Place the chocolate in a microwave-safe bowl and microwave at 50% power for 30 seconds. Stir, and continue to microwave in 15-second intervals until nearly melted. Add the oil and stir until fully melted. Alternatively, you can melt the chocolate in a heat-proof bowl over a simmering saucepan of water.
  • Pour the melted chocolate over the top of the cereal treats and spread it into an even layer.
  • Let cool at room temperature until firm, at least 2 hours. Cut into squares and enjoy.

Notes

If your chocolate has a dull or whitish finish when it hardens, you can lightly brush it with a very small amount of avocado oil or vegetable oil (I like to use the kind that comes in an aerosol can).
Since the treats are quite thick, I like to use a brisket knife to cut them into nice, clean squares.
You can make them in a 13×9-inch pan, but the treats and chocolate layer will be thinner. You may want to use 1 1⁄2 cups of chocolate chips and 1 1⁄2-2 teaspoons oil for the topping.
Prefer just peanut butter? You can skip the chocolate layer.

  1. LOL! I loved your “Even a woman on Weight Watchers broke down.” comment! These look mighty tasty and you did them up right all healthy like. When my kids were that little it always drove me crazy that they handed out gift bags with candy like that. Hello! The goodie bags were picked through by my hubby and I and we threw out the rest. Thanks for linking up!
