Ingredients

Scale

Main Ingredients:

  • 7 cups cornflakes
  • 10 ounces (283 grams) mini marshmallows
  • ¾ cup smooth peanut butter
  • 4 tablespoons salted butter

Flavor Enhancers:

  • ⅓ cup peanut butter chips
  • 2 tablespoons peanut butter chips (for drizzling)
  • 1 ounce (28 grams) mini marshmallows (to mix in at the end)
  • ½ teaspoon vegetable or canola oil

Instructions

  1. Prepare a parchment-lined baking sheet and set aside for cookie placement.
  2. In a large pot over medium-low heat, combine butter and peanut butter, stirring until smoothly integrated.
  3. Add majority of mini marshmallows to the melted mixture, continuously stirring until completely dissolved and creating a uniform consistency.
  4. Remove pot from heat and introduce cornflakes, gently folding to ensure thorough and even coating.
  5. Incorporate remaining marshmallows and peanut butter chips into the mixture, stirring delicately to maintain cornflake integrity.
  6. Lightly coat a cookie scooper with nonstick spray to prevent sticking.
  7. Scoop out uniform portions of the mixture onto the prepared parchment-lined sheet, creating approximately 10 cookies.
  8. Using lightly greased fingers, softly press each cookie to achieve a gentle, rounded shape approximately one inch thick.
  9. For the decorative drizzle, microwave peanut butter chips with oil in short 30-second intervals, stirring between each to create a smooth liquid.
  10. Transfer melted peanut butter mixture to a ziplock bag, snip a tiny corner, and artfully drizzle over each cookie.
  11. Allow cookies to rest and solidify at room temperature for 20-30 minutes before serving.
