Peanut Butter Cornflake Cookies Ingredients

Peanut Butter Cornflake Cookies ingredients.
  • Cornflakes cereal
  • Light corn syrup: This is often called by its name brand, Karo syrup.
  • Maple syrup: Any pancake syrup, maple syrup, pure or otherwise, should work in this recipe. You can omit this and use all corn syrup as well. 
  • White granulated sugar
  • Vanilla extract: Almond extract would be a good alternative. 
  • Creamy peanut butter: Use regular peanut butter rather than an “all-natural” brand. I used creamy peanut butter because I love a smooth texture, but you can use crunchy peanut butter to add extra texture to your cornflake cookies

See the recipe card for full information on ingredients and quantities.

Substitutions and Additions

  • Pick Your Peanut Butter: Either creamy or crunchy peanut butter will work for your cookies. Make sure to use processed peanut butter (like Jif or Skippy) rather than natural peanut butter for best results.
  • Nix The PeaNuts: To make these cookies allergy-friendly, you can swap the peanut butter for your favorite nut butter alternatives, such as almond butter, cashew butter, and SunButter. Be aware that different types may affect the texture slightly.
  • Swap The Cereal: In reality, you can use any type of flaky cereal in this recipe, including Special K, Rice Krispies, or Chex.
  • Customize Your Cookies: Feel free to decorate your desserts with mix-ins and toppings that match the occasion. Some ideas include shredded coconut, mini M&Ms, mini marshmallows, mini chocolate chips, sprinkles, or chopped nuts. You can either stir your add-ins in with the cornflakes or add them to the top of each cookie before they set.

How to Make Peanut Butter Cornflake Cookies

  1. Make The Peanut Butter Mixture: Heat the corn syrup and the maple syrup, stirring occasionally, until slightly bubbly. Turn off the heat, mix in the sugar and vanilla extract, and stir. Mix in the peanut butter.
    Pro Tip: The mixture will be very sticky. 
  2. Create The Cookies: Pour the mixture over the cornflakes and mix well. Scoop and drop cookies onto the baking sheet. 
  3. Set And Serve: Allow the cookies to set for 10-15 minutes and serve. Enjoy!

Tips For Making Peanut Butter Cornflake Cookies

  • Spray non-stick cooking spray over your parchment paper or wax paper. That way, your cookies will slide right off when it is time to serve. 
  • Lightly sprinkle water on your cookie scoop or spoon. Because this mixture is so sticky, the water will help prevent you from having the batter stuck to your utensils. 
  • Have your cookie sheet prepped and placed where you want to work. As soon as you mix the cornflake cereal and the sauce together, they need to go on the cookie sheet. If you wait too long the mixture will harden and it won’t be easy to work with. 

How to Store Peanut Butter Cornflake Cookies

  • To Store: Peanut Butter Cornflake Cookies are best stored in an airtight container at room temperature. They will last for up to a week.
  • To Freeze: You can freeze these cookies, wrapped in parchment paper and placed in an airtight container, for up to 3 months.

Frequently Asked Questions

Are these cookies gluten free?

A few brands of corn flakes are certified gluten-free, including Nature’s Path Organic Fruit Juice Corn Flakes, Barbara’s Bakery Organic Corn Flakes, EnviroKidz Amazon Flakes, and Nestle Gluten-Free Corn Flakes. Most other popular brands of corn flakes are not gluten free because they contain malt barley, which has gluten in it.

What kind of peanut butter is best for my cookies?

Creamy, crunchy, or nut butter alternatives will work for these cookies. Be aware that different types may affect the texture slightly. I don’t suggest using natural peanut butter. Since the oil is not blended in, there’s a potential that it can make the cookies greasy. Use regular no-stir peanut butter for this recipe.
