Peanut Butter Cornflake Cookies Recipe

Crunchy cornflakes cereal is stirred into a sweet peanut butter mixture to make this cookie that is so delightful!

I love the contrast that this classic cookie gives to more traditional Chocolate Chip Cookies or Magic Cookie Bars at the holiday.

Peanut butter and cornflakes are the prominent flavors in these cookie balls.  Corn syrup bonds the components together and gives a sweet flavor. These ingredients almost create a cross between a no-bake cookie and a candy that easily be rolls into balls.

This cornflake recipe reminds us of some of our other no-bake cereal treats like our Cheerio & M&M Cereal Bars, No-Bake Chex Cookies, and Cocoa Puffs Treats.

When I think about taking cereal and making dessert, Rice Krispie treats come to mind, but they are even better when modified a little to make Chocolate Peanut Butter Rice Krispie Treats and Oreo Cookie Treats.

What’s Needed To Make Cornflake Balls?

  • Cornflake Cereal – We typically use the store brand to save money without sacrificing quality.
  • Peanut Butter – Creamy is the only type we use in this flavor, but if you really like nuts crunchy would be okay.
  • Corn Syrup – Light corn syrup is the glue that holds this together and helps the sugar dissolve.
  • Granulated Sugar – Sweetens the cornflake peanut butter cookies.
  • Vanilla Extract – Enhances the flavors of all the other ingredients.
Ingredients needed to make peanut butter cornflake cookies are cornflakes, light corn syrup, granulated sugar, vanilla extract and creamy peanut butter on a white counter top.

Peanut Butter Cornflake Balls Recipe Tips

These no-bake cookies can be dropped onto a cookie sheet with a spoon and left to set up in a haystack style. 

Or they can be portioned out using a cookie scoop and then rolled in your hands to make balls.

Dip clean hands in water and shape balls in your hands by rolling.  The water will help prevent the mixture from sticking to your hands.

My kids enjoy easy recipes that don’t take very long and give them a hands-on opportunity to be involved.  Rolling balls make the cornflake treats fun to make and more fun to eat.

I tend to grab extra cereal from our pantry to make cereal desserts.  Be sure that the cereal is still fresh and not stale when you’re ready to make this recipe.  Grabbing slightly stale cereal is a mistake I regret to share that I’ve made more than once.

Another recipe in our box that uses cornflakes is our Red Potato Ranch Casserole.  These are great recipes to make as a pair and use up a box of cornflake cereal!

One of my childhood memories with food is eating the green cornflake wreaths at Christmas.  It is so pleasing to have a version of that recipe that is quicker and great to make all year round.

    I love to make this recipe but how do you keep them from getting dry and hard? What can you do to soften them when they get hard?
