Not so fancy in the kitchen? No problem! They’re no-bake and quickly made on the stove top…making it a recipe that even those who don’t consider themselves a pro in the kitchen can make!

Only 4 Ingredients!

  • Cornflakes: These give the cookies that amazing crunch.
  • Peanut butter: The creamy type works best. If it’s a runny peanut butter, the consistency won’t turn out how it should.
  • Sugar: Granulated sugar helps make the cookies sweet.
  • Corn syrup: The stickiness of the corn syrup helps give them that delicious chewy texture. Make sure to use white corn syrup.

How to make Cornflake Cookies

  1. 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.
  2. 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.
  3. Stir together and shape. 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.

Microwave Version

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.

Helpful Tips

  • Use a cookie scoop to scoop out the peanut butter mixture into even amounts. Then shape into balls with your hands.
  • Add 1 teaspoon of vanilla extract for extra flavor.
  • Drizzle some melted chocolate on top for an extra sweet touch!
  • Add a piece of wax paper in between each layer of cookies so that they don’t stick together.
  • I like to store my cookies in the fridge to make them extra chewy.

Storing + Freezing

Store any leftovers in an airtight container or bag for up to 3 to 4 days. I personally prefer to store them in the fridge, which extends their shelf life even longer (about a week). You can also freeze them as 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.
