Most people are probably currently trying to behave themselves and stick to their New Year’s resolutions, but I am not one of them. So for those of you who are, I apologize in advance for tempting you with these chewy and delicious Peanut Butter Cornflakes No Bake Cookies.

Seriously, I know, it seems completely unfair of me to dangle such a recipe in front of you while you’re trying to be good, but these are just too good not to share! Like addictively good!

Peanut Butter Cornflakes No Bake Cookies are an easy and sweet treat! Everyone will love these chewy, sweet, and salty cookies that are ready in no time at all!

I’m a huge fan of no bake cookies, my mom made them all the time when we were growing up and I continue to make them in tons of different flavors today, like my Irish Cream No Bake Cookies or my Peanut Butter No Bake Cookies.

Traditionally, I make my no bake cookies with an oatmeal base, but for this recipe I decided to try something a little different, Corn Flakes! Not overly sweet, this boring breakfast cereal pairs with the creamy peanut butter to create a wonderfully sweet and salty cookie!

Peanut Butter Cornflakes No Bake Cookies are an easy and sweet treat! Everyone will love these chewy, sweet, and salty cookies that are ready in no time at all!

They’re also SUPER chewy and my husband loves them even more than the classics. In fact, I packaged most of the batch up for him to take into work and they never made it because he keeps stealing cookies out of the container and there’s no longer enough left to share!

This recipe is made with just 5 ingredients: peanut butter, corn flakes, sugar, corn syrup, and vanilla. They’re made right on the stove top and are ready in minutes, and I promise the whole family won’t be able to get enough of them!

  1. This had been a recipe that had been passed down in our family for such a long time and I’ve never seen anyone else who had made these before. They are truly addicting and delicious!!!!

  2. I had Frosted Flakes and OMG these are the best things since sliced bread. The recipe goes on forever like they multiply when you arent looking at them. Yummy times ten.

  3. I used 1 cup of honey instead of corn syrup, and added a little bit of salt on each cookie. Turned out great! Thanks for the recipe!

  4. I followed the recipe. My corn syrup from Aldi had vanilla in it, so I did not add extra vanilla. Delicious! But clean up…not so fun. Once the leftover mix hardens, it’s difficult to clean the pan.

  5. I’m just now seeing this recipe and am thinking that now there are chocolate corn flakes this would be a fantastic combo! Will definitely try…soon

      1. I made these with Chocolate frosted flakes (I cut the sugar back to 3/4 cup and they turned out great. Going to make them next time with the cinnamon frosted flakes.

  6. Can I make this with Frosted Flakes?… I have all the ingredients on hand, with the exception of Original Corn Flakes. I have the sugar coated one.

  7. Amazing and Easy to make..I forgot to add the vanilla so I can only imagine how much better they would have been. Kids love them. They’re a hot at the Office as well.

  8. I received this recipe from a friend and OH my Gosh !!  soooo good.  Thank you Sarah Hare!!!!Love these 

    1. That sounds great Dorothy! And I’m so glad to hear you thought these were, dare I say, delicious!!

  9. Very easy and fast! These are delicious. I made them in just a few minutes. I added a very small handful of butterscotch chips in as well. Thank you for the recipe!

      1. Thanks for the clarification. That’s so high, but I suppose a lot of fancy cookies are. Won’t stop us from making them!

  10. Found this recipe when wanting to use up some cornflakes rather than throwing them away. My teenage granddaughter enjoyed helping, she used her hands and put the mix into cupcake holders. She finds them very tasty. Thank you :)

  11. Loved the recipe I’m a 63 year old man love to cook love my sweets this is a great sweet treat I tweaked it a little bit by adding 1/2 cup Karo along with 1/2 cup pure maple syrup gave it a nice taste

  12. These are totally yummy! I changed it up a bit as I didn’t have enough peanut butter. I substituted 1/2 cup of butter for 1/2 of the peanut butter. They turned out great!

  13. Got this recipe from my husband’s aunt early 60’s. The original recipe says to cook the sugar and a little salt with a bottle (16 oz.) dark Karo syrup just until boiling. Take off the fire and add the vanilla and 1 1/2 cups peanut butter, then stir until melted and pour over 10 cups of corn flakes before molding into shape and putting onto buttered wax paper to cool. The name of the recipe is Peanut Butter Chewies.

  14. Make with chocolate frosted flakes and toss in about half a cup of milk chocolate chips. My kids say they taste like a peanut butter cup. 

  15. My grandmother made these when I was growing up, although i don’t remember peanut butter in hers. I’m gonna get some Corn Flakes and make these.
    Thanks for posting.

  16. These are super easy and everyone loves them. I added a half stick of butter for a creamier coating. I didn’t have regular corn flakes, so frosty flakes made their debute! Not recommended for anyone with sugar issues! The sweetness is delicious!

  17. My husband works out of town, and I sent about 15 of these candies with him. How long will they stay good? I wrapped them individually in plastic wrap. 

  18. I made this after looking for something to do with my leftover corn flakes from my christmas funeral potatoes,and I LOVED THIS! so easy and so Yummy!

  19. The first time I made this recipe they were perfect! The second time I made, followed the same exact recipe, they got very hard.  Do you know what could cause that?  Maybe mixing too much?  

    1. Hi Tammy,
      I have found that you can generally reduce the sugar in any recipe by 1/3 without altering the flavor.
      I hope this helps!

  20. My grandmother use to make these when I was younger. The only difference is she would put them in a pain like you do with rice crispy treats and top with melted chocolate.

  21. Thank you soo very much!! I made these cookies and i was instantly brought back in time to my childhood, making these with my grandmother ♡ now my grand kids & i will be making memories over this recipe also♡ Thanks again

  22. Ok, I think I messed up something.  They really didn’t harden per say and fell apart once you tried to pick them up.  The mixture tasted delicious but nothing like a cookie form.  What do you think happened?   I’d like to try this recipe again, but have them look like your cookies.  

  23. A few tips I have learned….
    (I’ve made these with rice krispies, cornflakes, and Cheerios.)
    I find they need packed in a bit, so I drop them by tablespoonfuls onto waxed paper. They leave loose cookies. Working quickly before they completely cool, I coat my hands in butter (or margarine or coconut oil) and pack them in ball shaped cookies. I find if you do this when they’re too warm, they just fall apart again, so partially cool works best. And when they start to stick to my hands, I recoat my hands with butter. (This works well with many sticky doughs!)

  24. My family has been making these for over 60 years. My Granny made them for us when we were kids. Now I make them for my children and grandchildren..

  25. What if the cornflakes are very lightly toasted first? I made cowboy cookies with oats, pecans, cornflakes, and coconut and they tasted raw…I kept thinking they would have been more flavorful if I had toasted all the ingredients first

  26. Hi…I’m salwa from malaysia…I’ve try ths recepy couple of years…my opinion try add 1 teaspoon of butter after mixed all ingrediants….after scoop try baked in oven just around 5 to 10 minits….hehe…and agree used crunchy peanut butter…is so yummehhh……juz my 2 cents…:p

  27. I have made a variation of this recipe for 40 years.  It is basically the same thing with just a couple of adjustments.  I’m sure whatever works for you is fine but I stir in my peanut butter only after I bring my mixture of sugar and Karo to a boil.  Then I pour that creamy mixture over my pre-measured out bowl of corn flakes while I stir and coat.   Then after they are sufficiently coated, I  pour them out in to a greased 9×11 dish to let them set so they can be cut into squares.   Yummy!  (Also I use 8 cups of corn flakes and no vanilla…but I’m sure it’s delicious!)

  28. Teen boys loving this in the am, made this four times this summer :)
     I tend to forget the vanilla -oops! 
    Sprayed an ice cream scooper w oil and it comes off into rounds much easier. 

  29. I just made them. I added a few mini chocolate chips but think I will leave them out next time, made them a little too sweet. I wrapped all but two to give away because they are so addictive and clearly not on my dieters list. I think I ate two before I finished scooping them out and putting on wax paper.

  30. My mom made these when we were kids. She called them Energy Bars! Sugar content is high, but they are ohhhhh soooooo good!

  31. to make the bar cookie, did you pat down the mixture on the cookie sheet or just put it on top until it cooled off.

  32. I have made these for years, but I use half Corn Flakes and half Rice Krispies. I have also put the mixture onto a cookie sheet and cut them like a bar cookie. No matter which way you prepare them, they are so addictive.

  33. My dad wants a molasses flavor in the cookies. Can you add molasses to the mixture and it still turn out good?

    Thank you

    1. I have not tried to freeze them, but if you decide to try it please let me know how it turns out!

    1. I like to make this recipe as written, but feel free to try other cereals. Let me know how it turns out.

  34. Made these today, and it was so good that my sister and I just started eating it right out of the mixing bowl!! Amazing cookies, even my mother who is extremely picky about her food enjoyed it. :) thanks!!

  35. I make these every Christmas. I cook the mixture in the microwave. Then add green food coloring. I pat each one down & add some red cinnamon pieces. The cornflakes look like leaves.

  36. My grandmother cooked in the school lunch room when I was in school and she made these, believe me it was a long time ago. Back then they had to use what the government gave them to use. Thanks for the memory.

    1. Hey Bev, I just found this recipe and YES I can’t believe that I too had this when I was very young. Had forgotten about it. But I’m gonna make them now for my daughter and grandkids. I hope that they will Love them as much as I did.

    2. What brought back the memory was a new Hershey bar called Hershey’s Gold. It has peanuts and pretzels in a caramelized creme. There was a familiar flavor that I caught every time I took the first bite, but just couldn’t get it. Bit O’ Honey? Not quite. Tigers Milk bars? Nah. Then when I remembered there were peanuts, I went to peanut butter, and then it hit me with a huge smile–my favorite elementary school cafeteria treat! (1950s-60s) I tried making them as a kid with just peanut butter and sugar, and of course corn flakes, and they came close but now I know the real recipe. Can’t wait to make a batch!

  37. I made this recipe today and it tasted really good until the cookies stuck to the wax paper and it was extremely hard/impossible to get off. Maybe it’s best to use cooking spray or use another surface?

        1. Me too!! I knew the recipe by heart but since I hadn’t made them in a few years I decided to Google it. It seems like I used less corn syrup but this recipe coats the corn flakes better. Just as good as I remembered!

      1. For chewier, less crunchy cookies, I like to keep the heat on until all the corn flakes are combined. I’ve made these since I was a kid and prefer them this way. Hope this helps
