Get ready for a fun twist on cereal bars with these chocolatey, peanut buttery treats!



For bars:

  • Cooking spray
  • 3 tablespoons unsalted butter
  • 1 (10 ounce) bag marshmallows
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon pure vanilla extract
  • 6 cups Reese’s Puffs cereal

For topping:

  • 1/2 cup white chocolate chips
  • 1 tablespoon unsalted butter, softened
  • 2 tablespoons creamy peanut butter
  • 1/4 cup powdered sugar
  • 12 tablespoons milk, as needed


  1. For bars: Coat 13×9″ pan with cooking spray. Melt butter in a large saucepan over low heat. Add marshmallows, salt and vanilla and continue to cook, stirring constantly, until completely melted.
  2. Remove marshmallow mixture from heat and add stir in cereal until well coated. Press mixture evenly into prepared pan. (Use a silicone spatula or wax paper to prevent the marshmallow from sticking to your hands)
  3. For topping: Pour white chocolate chips into a microwave safe bowl. Microwave until fully melted and smooth, stirring after every 30 seconds. Drizzle melted chocolate over bars (I used a fork, drizzling the chocolate from a few inches above the bars for a more even coating).
  4. In another bowl, mix together the butter and peanut butter. Add powdered sugar, 1 tablespoon at a time, mixing after each addition. Once well mixed, add milk, 1 tablespoon at a time, until the mixture is smooth enough to drizzle. Drizzle over bars.
  5. Cover pan and refrigerate until firm. Cut into squares to serve. Enjoy!
