Ingredients

  • 4 tablespoons salted butter
    Provides a rich base flavor; salted butter balances the sweetness.

  • ¾ cup smooth peanut butter
    Offers creamy texture and nutty taste; smooth peanut butter ensures even mixing.

  • 10 oz mini marshmallows
    Acts as the sweet binder; mini marshmallows melt quickly and evenly.

  • 7 cups cornflakes cereal
    Adds crunch and structure; ensure they are fresh for optimal texture.

  • 1 oz mini marshmallows (reserved)
    Folded in at the end for extra gooey pockets.

  • ⅓ cup peanut butter chips (optional)
    Enhances peanut butter flavor; optional for added sweetness.

  • 2 tablespoons peanut butter chips (for drizzle)
    Used for the finishing touch; creates an appealing visual and flavor accent.

Directions

  • Melt Base Mixture:
    In a large pot over medium-low heat, melt the butter and peanut butter together, stirring until smooth.
    Add 10 oz of mini marshmallows to the pot, continuing to stir until fully melted and combined.
  • Incorporate Cornflakes:
    Remove the pot from heat.
    Gently fold in the cornflakes until they are evenly coated with the marshmallow-peanut butter mixture.
  • Add Reserved Ingredients:
    Fold in the reserved 1 oz of mini marshmallows and the optional ⅓ cup of peanut butter chips, mixing just until combined to maintain pockets of gooeyness.
  • Form Cookies:
    Line a baking sheet with parchment paper.
    Using a large cookie scoop or spoon, portion out 10 equal mounds onto the prepared sheet.
    Lightly grease your fingers and gently press each mound into a cookie shape, about 1 inch thick. Avoid compacting too much to keep them light and chewy.
  • Prepare Drizzle:
    In a microwave-safe bowl, combine 2 tablespoons of peanut butter chips with ½ teaspoon of oil.
    Microwave in 30-second intervals, stirring between each, until the mixture is smooth.
    Transfer the melted mixture into a small zip-top bag, snip a tiny corner, and drizzle over each cookie.
  • Set and Serve:
    Allow the cookies to set at room temperature for 20–30 minutes, or until firm.
    Once set, enjoy immediately or store as directed below.
