Ingredients

Scale

Base Ingredients

  • 4 cups cornflake cereal
  • 1/2 cup peanut butter
  • 1/2 cup syrup (corn syrup recommended)
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract

Decoration Ingredients

  • 1 cup white chocolate, melted
  • 1 tablespoon dark chocolate (for eyes and mouth), melted
  • 18 marshmallows

Instructions

  1. Make the caramel base: Add the sugar, corn syrup, and peanut butter to a saucepan and heat over medium heat. Stir continuously to avoid burning as the mixture melts and becomes smooth and caramel-like. Once silky, remove from heat and mix in the vanilla extract and salt thoroughly.
  2. Shape the cookies: Pour the warm peanut butter mixture over the cornflakes in a large bowl. Gently stir with a spatula to evenly coat all the cornflakes without crushing them. Using a size 20 cookie scoop, scoop out small mounds onto parchment paper or a lined baking sheet. Press each mound gently to maintain shape and allow them to cool at room temperature until set.
  3. Decorate for Halloween: Melt the white chocolate and spoon a small amount on top of each cookie. Dip a marshmallow into the melted white chocolate, tap off excess, and place it on top of each cookie to create a ghost shape. Let the cookies set completely, either at room temperature or by refrigerating to speed the process. Once set, use a toothpick dipped in melted dark chocolate to carefully draw spooky eyes and mouths on each marshmallow ghost.

Notes

  • Use a gentle hand when stirring cornflakes to avoid crushing them.
  • Substitute the corn syrup with golden syrup or honey if corn syrup is unavailable, though texture may vary slightly.
  • To speed up setting time, refrigerate the cookies for 20-30 minutes after assembling.
  • Ensure the peanut butter is well-stirred before measuring if natural peanut butter is used to avoid oil separation.
  • Dark chocolate can be melted in short bursts in the microwave or over a double boiler for best control.
