    Only 4 ingredients!

    • Corn flakes cereal
    • Creamy peanut butter
    • Sugar
    • White corn syrup

    How do you make cornflake cookies?

    Add cornflakes to large bowl. To get started, line a baking sheet with parchment paper and add 3 cups of corn flakes cereal to a large bowl.

    Cook peanut butter mixture. Next add sugar and syrup to a saucepan and cook over medium-heat until mixture begins to bubble. Then stir in peanut butter until dissolved.

    Stir together and shape into balls to harden. Once peanut butter mixture is smooth, pour over the cornflakes and gently stir until covered. Shape into small round balls and place on parchment paper to harden. Let cool for 15 to 25 minutes before enjoying.

    Can you make them in the microwave?

    If you’re in a big pinch, you can remove the whole stove top component completely and make them in the microwave.

    Just add the sugar, corn syrup and peanut butter in a large glass bowl (or 8 cup measuring bowl) and microwave for about 3-5 minutes until bubbly, stirring often. Then add in cornflakes and gently stir until combined.

    Tips

    • Store in an airtight container or bag for up to 1 week.
    • Add a piece of wax paper in between each layer so that they don’t stick together.
    • I like to store my cornflake cookies in the fridge to make them extra chewy.
    • Use a cookie scoop to scoop out the peanut butter mixture into even amounts. Then shape into balls with your hands.
    • Add a chocolate drizzle on top for an extra sweet touch!

    Yes, these cornflake cookies freeze very well! Once they’ve hardened, just add them to a freezer bag or container and store in freezer for up to 1 month. When ready to enjoy, remove from freezer about 10 to 15 minutes beforehand.
