A Classic No-Bake Cookie

This cornflake cookie recipe requires no baking at all, a perfect way to enjoy a treat in the summer when you don’t want to heat up the house with that oven.

But one of my favorite times to make these easy peanut butter cornflake cookies is during the holiday season.

In fact, it’s a recipe I often make for the cookie swap at church. I made it one year, and ever since, people have begged for it to be a part of the lineup.

But because I’m southern, I have to make a ton of other cookies. What’s a holiday if you don’t have tons of cookies to nibble on, right?

After that particular cookie swap, I had no less than a dozen phone calls demanding to know what was in this recipe. Everyone seemed stunned that it only called for a few simple ingredients. 

Anyway, if you’re looking for a cookie that everyone will love and you want something that uses basic ingredients, you’re absolutely in the right place at the right time!

I always put them out on my holiday table for family and friends, and once, I made the huge mistake of not setting one aside for myself to enjoy later. They were all gone in the blink of an eye!

How To Make The Crunchy Peanut Butter Cornflake Cookies

1. Pour the Corn Flakes into a large heat-safe bowl. Line a cookie sheet with parchment paper.

2. Add the sugar and corn syrup to a medium saucepan and cook on medium heat to medium-high heat.

3. Bring the two ingredients to a boil, stirring often. Boil for about two minutes or until the sugar is dissolved.

4. Add the crunchy peanut butter to the saucepan and stir quickly to combine the ingredients. 

5. Pour the mixture over the Corn Flakes and stir quickly to coat. 

6. Spoon the cookies onto parchment paper and allow them to harden and set up. The cookies will set up and harden fast. 

Step-By-Step Instructions

Start by pouring the sugar into a saucepan.

Pour the light corn syrup into the saucepan with the sugar.

Mix well to combine.

Bring the two ingredients to a boil. Boil for two to three minutes or until the sugar is dissolved.

Remove from the heat and stir in the crunchy peanut butter to combine.

Work quickly because the corn syrup mixture will harden fast. 

Pour the mixture over the Corn Flakes and toss to coat. 

You will want to work quickly because the corn syrup will harden fast again. 

Spoon the mixture onto some parchment paper or onto a cookie sheet and allow the cookies to harden. 

They will harden fast. They can be a little crumbly, as well. If they are cool enough, I press them together with my hands.

Easy Peanut Butter Cornflake Cookies

To make these peanut butter cornflake cookies, you will need only a few things – peanut butter, sugar, light corn syrup, and cornflakes. That’s it!

I use chunky peanut butter, but you can use creamy peanut butter or natural peanut butter if you like. Your favorite brand of cornflakes will work just fine here. 

They’re almost like peanut butter candy, making them great for holiday gifts. Once they set up, they’re very chewy, like semi-hard candy. You make them on the stovetop, and that’s it.

You can also make them into chocolate peanut butter cornflake cookies by adding a drizzle of melted chocolate, or feel free to do the same with white chocolate chips or butterscotch morsels too. 

Optional Ingredients

• Chocolate chips
• Butterscotch chips
• Mini marshmallows
• Small pretzels

If you decide to add any of these ingredients, add them as you are stirring the syrup and Corn Flakes.

How To Store The Peanut Butter Corn Flake Cookies

Store the cookies in an airtight container or cover with plastic wrap. They do not have to be refrigerated.

If you want to freeze the cookies, place them in a freezer-safe container and freeze for up to two months. Place them on the counter to thaw.

Can I Use A Cookie Scoop?

A spoon is going to work better than a cookie scoop. And you want to work fast to get the cookies out on the parchment paper.

Can I Get Frosted Corn Flakes?

This is your dessert, so you definitely can! For this recipe, I bought the plain cornflake cereal, but you can get Frosted Flakes if you want to.

Peanut butter cornflake cookies are definitely the answer to those sweet cravings you’re having. I simply adore making this sweet treat because it takes no time at all, and the results are absolutely delicious.

If you need a simple cookie to bring to a potluck or for dessert any time, you’ve got to make them!
