Peanut Butter Rice Krispies Treats

These Rice Krispies Treats cater to peanut butter and chocolate enthusiasts! They feature peanut butter, mini Reese’s® cups, and a velvety peanut butter-chocolate topping. Their texture is gooey and crunchy, while the taste is rich. Additionally, they’re quick and simple to prepare, requiring no baking.

We prepare Rice Krispies Treats throughout the year, but their frequency increases during summer. This is when we desire something sweet but prefer not to warm the house with the oven.

Note: ‘Rice Krispies’, ‘Fruity Pebbles’, and ‘Reese’s Cups’ are trademarks of various cereal and candy companies. In our recipe, we mention these names for clear identification; however, any similar product can be used as a substitute.

Ingredients In Peanut Butter Rice Krispie Treats

  • Rice Krispies cereal: This is the main ingredient, providing a light and crunchy texture.
  • Unsalted butter: Adds richness and helps hold the ingredients together.
  • Brown sugar: Sweetens the treats and, when cooked with butter, gives a caramel-like flavor.
  • Heavy cream: Makes the caramel mixture creamy and rich.
  • Creamy peanut butter: Flavors the treats and helps bind them together. It’s also mixed with chocolate chips for the topping.
  • Mini marshmallows: Used for sweetness and to make the treats gooey, some are melted and some are mixed in whole.
  • Vanilla extract: Adds a nice aroma and taste to the Peanut Butter Rice Krispie Treats.
  • Mini Reese’s cups and milk chocolate chips: These add extra chocolate and peanut butter flavor, especially in the creamy topping.

Equipment

  • 9 x 9-inch pan
  • Parchment paper

Ingredients

  • 5 cups Rice Krispies cereal or other crispy rice cereal
  • ½ cup unsalted butter
  • ¾ cup light brown sugar, packed
  • cup heavy cream
  • ½ cup + 2 ½ tablespoons creamy peanut butter, separated
  • 2 cups + ½cup mini marshmallows, separated
  • pinch of fine sea salt
  • 1 teaspoon vanilla extract
  • ¾ cup mini Reese's cups (See Note 1)
  • 1 ½ cups milk chocolate chips

Instructions

  • PREP: Prepare a 9x9-inch baking pan by lining it with parchment paper. Measure and add the cereal to a very large bowl and set aside.
  • BUTTER AND BROWN SUGAR: In a medium-sized saucepan, add the butter and heat over medium high. Once the butter is completely melted, add brown sugar and stir until the sugar is completely dissolved, 1-2 minutes. 
  • BOIL CREAM: Stir in the heavy cream, and bring to a boil, stirring constantly. Boil for 1 minute, then turn the heat down to medium low.
  • ADD PEANUT BUTTER AND MARSHMALLOWS: Stir in ½ cup peanut butter, 2 cups miniature marshmallows, and pinch of sea salt. Stir until the marshmallows are melted and then remove from the heat and add the vanilla extract.
  • POUR OVER CEREAL: Pour mixture over the cereal and gently stir to combine. Add the remaining ½ cup marshmallows. Stir until coated. Then gently stir in the miniature Reese's cups (they'll get pretty melty!)
  • PRESS INTO PAN: Pour the mixture into the prepared pan. Gently press the cereal mixture into the bottom of the pan. Don't push too hard, or it will compress the bars and make them too hard.
  • TOPPING: In a small microwave-safe bowl, combine chocolate chips and remaining 2 and ½ tablespoons peanut butter. Microwave in bursts of 15 seconds, stirring in between each burst for 10 seconds until melted and smooth. Spread the chocolate peanut butter mixture over the cereal bars in an even layer. Chill for 30 minutes in the fridge to set the chocolate, and then remove the pan from the fridge and let stand until at room temperature. Cut into bars and serve.
  • STORAGE: These bars are best eaten the same day they are made. Keep them in an airtight container at room temperature. Read post for how to freeze/thaw.
