Equipment

  • Saucepan
  • Baking Sheet
  • Ice cream scoop
  • Parchment Paper

Ingredients
 

  • 1 cup granulated sugar
  • 1 cup light corn syrup
  • 1 cup creamy peanut butter
  • 1 teaspoon vanilla extract
  • 6 cups corn flakes

Instructions
 

  • Heat the sugar, corn syrup, and peanut butter together in a large saucepan over medium-high heat, stirring continuously across the bottom. Watch for active bubbles breaking through the center of the mixture, which signals that heating should stop.
  • Move the saucepan off the burner immediately, then incorporate the vanilla and fold in the cornflakes. Finish folding when a glossy peanut butter coating covers the flakes evenly, without dry pockets of cereal.
  • Portion the warm mixture promptly onto parchment paper with an ice cream scoop. The coating thickens as it cools, so the clusters should release more easily while the mixture remains warm.
  • Leave the cookies undisturbed on the parchment for 20 to 30 minutes. The clusters should cool enough to hold their shape when lifted, with a less glossy surface and a chewy interior.

Notes

Boiling cue: Take the saucepan off the burner the moment bubbles actively break through the center. Boiling too long causes moisture loss and turns the cookies hard and brittle.
Peanut butter choice: Use conventional, no-stir creamy peanut butter. Natural varieties with separated oil can produce greasy clusters that struggle to set firmly.
Storage: Store cooled cookies in an airtight container at room temperature in a cool, dry location. Place sheets of wax paper or parchment between layers to keep them from sticking together.
