You do have to move fast once you mix the cornflakes into the peanut butter mixture so that it doesn’t harden, but there are still plenty of ways to get the kids involved! Ella helped measure out all of the ingredients into the saucepan before I placed it on the heat, and then as I quickly scooped the candy-coated cornflakes onto our baking tray, she was in charge of adding the festive sprinkles.

These cookies are incredibly versatile and you can change up the recipe according to your personal preferences:

  • add some melted chocolate chips for a peanut butter-chocolate twist
  • add food coloring for bright pop of color
  • add in chopped nuts for added crunch and salt
  • drizzle white chocolate or candy melts overtop for a fancy touch

Cornflake Cookie FAQs

How to store Peanut Butter Cornflake Cookies: store in an airtight container at room temperature for a few days, or in the fridge for up to a week. While some people have reported that they have frozen and thawed out the cookies with no issues, I find that freezing and thawing makes them a bit soggy which I don’t enjoy.

Can I use natural peanut butter to make cornflake cookies? You will need to use a commercial peanut butter for best results (texture and flavor) for this recipe. Natural peanut butters can vary in oil content and the candy coating may not set if you opt for natural peanut butter. 

Can I swap out the corn syrup for honey or maple syrup? I haven’t tried this but it should work out fine.

Kitchen Tools You May Find Helpful

  • Measuring cups and spoons
  • Saucepan
  • Wooden Spoon or Spatula <– I like these spatulas because they are one solid piece and don’t have removable heads for bacteria to get trapped underneath. Plus they are heat-resistant and have a lifetime warranty.
  • Cookie Sheet <– you will want two so you can bake one tray while the other is cooling
  • Parchment paper or Silicone Baking Mats
  • Cookie scoop
