Ingredients

  • 4 cups cornflakes cereal
  • 1 cup creamy peanut butter
  • 1 cup light corn syrup or honey
  • 3/4 cup granulated sugar
  • 1 tsp vanilla extract
  • Pinch of salt

Instructions

  1. In a saucepan over medium heat, combine the granulated sugar and corn syrup (or honey).
  2. Stir constantly until the mixture begins to boil gently, then remove from heat.
  3. Stir in the peanut butter, vanilla extract, and a pinch of salt until smooth and fully combined.
  4. In a large bowl, pour the peanut butter mixture over the cornflakes.
  5. Gently fold the mixture until the cornflakes are evenly coated.
  6. Drop spoonfuls of the mixture onto a parchment-lined baking sheet using a spoon or cookie scoop.
  7. Let the cookies cool at room temperature for about 30 minutes until set and firm.

Notes

  • Use regular creamy peanut butter for best results; natural peanut butter may cause the cookies to be too soft.
  • Honey is a great substitute for corn syrup and adds extra flavor.
  • To speed up setting, place the cookies in the fridge for 10 minutes, but allow them to return to room temperature before serving.
  • Add mini chocolate chips, marshmallows, or chopped nuts for variation.
  • Store in an airtight container at room temperature for up to 5 days.
