These chewy no bake Peanut Butter Cornflake Cookies are an easy dessert with few ingredients. Plus, they’re better than what Grandma used to make because there’s NO corn syrup to boil while standing over the stove. Shhh…we won’t tell!
(But yes, there IS corn syrup in the marshmallows. we know that.)
They’re similar to your favorite Rice Krispies treats and just as quick to make.
I absolutely love a recipe that’s been around for years.
You know, like the ones Grandma used to make – Italian Bread, Three Bean Salad, Crockpot Spareribs, and others.
They are tried and true recipes.
They’re the ones that have been around for generations.
That’s because people have made them and loved them again and again.
They’re a wonderful thing. Relics in a way, and ones we can pass on to future generations.
This cornflake recipe is just that.
While I’ve never even had a Cornflake Cookie, I knew I had to give this recipe a shot since I’ve seen them around for years.
SAVE THIS EASY CORNFLAKE COOKIE RECIPE TO YOUR FAVORITE PINTEREST BOARD!
Yes, I’m just as shocked as you are that I’ve never had one.
Now I’ve fallen in love with them just as you may have.
A difference with my recipe and many, if not most of the others, is I substituted marshmallows for the corn syrup.
While corn syrup does have its’ place in many recipes, like how my mom used to make these O’Henry Bars, I wanted to see if they could be made without it, and VOILA!
I think you’ll be pleased with the outcome. My family certainly was and these babies didn’t last long at all!
What Ingredients I need to make these cookies with cornflakes in them?
- Cornflakes, of course. They wouldn’t be Cornflake Cookies without them!
- Butter – salted or unsalted, but I prefer salted.
- Marshmallows – NO Corn Syrup to boil, folks!!
And yes, I know, there usually IS corn syrup in marshmallows.
I use the miniature marshmallows because they’ll take less time to melt.
- Peanut butter – I use creamy, but the peanut/crunchy would work as well.
- Pure vanilla extract – yes, you can use vanilla extract if you’re not using the pure, but PLEASE don’t use the imitation! It really does make a difference and you aren’t doing yourself a favor even if you are saving a few pennies.
Are these no bake Cornflake Cookies easy to make?
They sure are! Keep reading!
- Melt butter in a large pot over medium heat.
I highly recommend using a non-stick pot. For years, and I do mean YEARS, I used just a regular pot to make various Rice Krispies treats, like this one. FINALLY, I bought a non-stick pot and it seriously changed my life. No joke.
- After the butter has melted, pour in the marshmallows and continue stirring until melted. Add the peanut butter and vanilla, and mix until smooth.
- Pour in the cornflakes and stir until well combined and covered.
- Using a tablespoon or a small cookie scoop, place scoops of the mixture onto a non-stick baking sheet.
- Allow to cool completely and harden.

I don’t like pumpkin pie at Thanksgiving, but I will HAPPILY eat the Pumpkin Dream Bars any day of the week! They’re going to be a regular on our Thanksgiving menu for sure.

Comments & Reviews
You do know that the first ingredient in marshmallows is corn syrup! So, not better for you than grandma’s!
Yes, Kendra, I am aware that there is corn syrup in marshmallows. I say there’s no corn syrup in them because many of the other recipes I’ve seen include it as a main ingredient. I wanted to give people the option of not using it. Also, I think they are better than grandma’s because I like the way they taste with the marshmallows more. But it is a personal preference.
I did NOT know that Lynne THANK YOU!! I didn’t have any corn syrup so was looking for an alternative and came across the best recipe EVER!!
She did not say they were better for you.
Anita Locantore says
Right!? In fact she specifically said there was corn syrup in the marshmallows! Her fabulous recipe is just giving those of us who don’t keep corn syrup in our pantries an alternate replacement. For the life of me I cannot figure out why people are so eager to be negative about EVERYTHING.

Hi Lynne —
In looking for a substitute for corn syrup several months ago, I ran across something called Golden Syrup. It seems to be common in England but not so much here. I have substituted it in recipes where corn syrup is a major ingredient, and it has worked very well. It’s super easy to make and keeps reasonably well.
Thanks for your fun recipes,
Barbara, thank you so much, I appreciate that. I’m so glad that this has worked out for you and thanks for leaving a comment so that it will help others!
Hi I just came across this recipe as I lost the recipe I use to use and it was years ago so can’t recall the ingredients! We have a store here in MS. That sells these individually packaged and they’re perfect to my liking but expensive. The recipe I tried lastnight online was far too gooey and chewy for me and not as crunchy and dry as I like them! I was wondering what sort of texture these have?
These cornflake cookies remind me of a rice krispies treat. I thought they had an equal amount of gooey and crunchy. Hopefully they’re just the way you like them, LaceyBug!
I made the corn flakes and peanut butter cook they are so good just plane, but I drizzled nuella over them and they went to a good cookie to a great one !
Thank you, Eve! And great idea with the Nutella, too!
Could you use Frosted Flakes instead of cornflakes?
You most certainly could, Mary. They might be a bit sweeter because they already have a sugar coating, but they’ll work.
This is an oldie but good recipe. I have made it with frosted flakes too.
I pack this into a pan, drizzle melted chocolate on top, put some sprinkles – and family is wowed by how great it is. And so easy – I have the grandkids make it when they come over.
Love this recipe! I’ve made it 3 times in the last month. Today I used up what was left of the cornflakes, crispy rice cereal and toasted cinnamon square cereal which was about 6 cups. Turned out great! Thanks for this recipe!
Haribo hat Marshmallows ohne Maissirup, es wird Glukosesirup verwendet.
Haribo has marshmallows without corn syrup, they use glucose syrup.
Thanks so much for the information, Jesse-Gabriel!
Kids love them.
I tried the recipe, it’s really good.
How much of each ingredient?
Danielle Wavrin says
If you scroll down to the bottom of the page, you’ll see the recipe and the amount of each ingredient. Enjoy!
Nicole, the amounts for all of the ingredients are in the recipe card which is down at the bottom of the post.
Just made these and they are one of my favorites! I love that you used marshmallows instead of karo/corn syrup, too! Who cares if corn syrup is the first ingredient in marshmallows?! Seriously! Don’t make them, if it bothers you! I thought they were easy enough to make and taste just like something my grandmother would have made!
Also, I made two batches (for holiday treats) and after making my first batch, I realized how quickly the marshmallow mixture starts to set, so when I made the second batch, I sprayed my bowl that had the cereal in it (before adding cereal) with Pam, then sprayed my hands to roll balls! It worked like a dream!
