The premise of this recipe is good, however 10 cups of flakes was WAY to much for the amount of sugar/ corn syrup/ peanut butter mix. Mine was too dry and barely stuck together. I would suggest 6 cups of cornflakes.
Laura Wilson
I didnt read reviews prior either….waaah. Too many flakes….they want to fall apart when cutting them. IF I make them again definately will cut back the corn flakes.
Daniel Berg
A new favorite! After reading the reviews, I cut down the cornflakes to 9 cups. This yielded a chewy textured bar similar to that of homemade rice krispy treats. I also substituted crunchy peanut butter & it worked perfectly.

Easy recipe that the kids love getting in their lunch box. I make it with Wow butter (soy) as they aren’t allowed peanuts or tree nuts at school or summer day camp. It is very sweet so it is a treat for them. I will probably experiment with a bit less sugar or mixing with healthier cereal
Roger Calhoun
Not a bad recipe but not nearly enough mix to cover the cornflakes. Will try it again using half again as much of each ingredient. 1.5 cups of peanut butter, syrup and sugar should cover much more adequately
Mark Watson
I used a whole box of corn flakes (17 cups, according to the label) and doubled the other ingredients. I pressed it into my 11×17 baking sheet, n they came out thick, but still fit in the sheet. So good! The best part was eating the extra off the mixing spoons. Will definitely make again!
Robert Miller
Been making these for years but I only use 5 cups of cornflakes and I drop them on wax paper

I read several reviews before making this…Do not lower the cereal amount, add a stick of butter to the sugar and corn syrup. Let boil for 2 minutes. I only had about a 1/2 cup of corn syrup and wasn’t running to the store, so I used honey to finish off the cup. They are amazing. The little bit of honey gave them a hit of flavor. I may try them without the honey to compare but I will definitely make them with it again.
Jared Bird
Used to get these in school , very tasty . I agree with other reviews that flakes need cut back to 6-7 cups . More chew and better taste
Elizabeth Brown
I made this and followed the recipe just as described but will definitely reduce the cereal to 7-8 cups. It was a little dry for the 10 cups. Overall a great recipe!!

I’ve made these before and lost the recipe. My children grew up eating these cookies. So simple to make but yummy. I agree with cutting the cornflakes back to 8 Cups. I’ll have to try the frosted flakes rather than cornflakes. Sounds good. I remember actually adding chocolate chips occasionally, when I was dropping them from a spoon. One thing I did do was lightly spray the bowl before adding the flakes and covering them with the hot liquid. It made it easier to stir the mixture into the cornflakes. I’ll be making these tomorrow.

This stuff is incredible and super easy and quick!!!! I used it for a party and it was consumed! I only got one piece. I used organic cornflakes and peanut butter and it was just perfect. I’m going to go make more now.
Mark Webster
I had to use a little less cornflakes that the recipe called for and I still had some flakes that were not sticking to the mass. These were just okay for me.. but they were super easy, quick, cheap and healthy so I am keeping the recipe and maybe adding a few mini choco chips or nuts next time.

I make a pan of these every week to go in the kids’ lunch boxes. They love them & the other kids beg for a bite. Literally! Too funny! Here’s how I like to do it: First off, use just about any kind of left over odds & ends cereal you may have languishing in the pantry, as long as it’d taste good with peanut butter. I’d think Trix, or any other fruity cereal would be a no-no, but any flavor Cheerio (banana is awesome), chocolate cereal, Kix, Chex etc work great. Shoot, I’ve even snuck in a handful of crunchy chow mein noodles here and there without issue & it was all good. Lol. Just mix it all up. About 6 cups worth of whatever you’ve got plus 4 cups cornflakes, or even Honey Bunches of Oats etc. I’ve never tried without some type of flakes added for the end texture, but it may even work without them. I add about 1/3 cup of ground flax seed to the dry cereal ( you can add wheat germ too), & I change the white sugar to brown, using 1/2 a cup ( just curb the sugar a little, not due to taste – a full cup is fine ). Use 1 cup creamy p.b., then add an extra 1/4 cup of crunchy p.b. because my kids like the extra nuttiness. Press down HARD into a lightly sprayed 13×9 by laying a piece of saran or wax paper over the top & mashing it. I enlist my hubby for this. Pack it in pretty tight, especially in the corners, or it won’t stay in squares when you cut it! You can sprinkle a handful of mini chocolate chips or Reese’s pieces over the top to make it extra special. 😉

I haven’t tried making these myself yet, but I bought a couple at a bake sale and they are so amazingly delicious. The ones I had were really good but they were hard and very chewy. I want to make them for my son’s 3rd birthday but since the kids are younger (toddler and preschool age) does anyone know how I can makes them a little softer and easier to chew?
Grace Morrison
This was just like we used to get in elementary school. It was and still is a great little treat. Easy to make and great flavor too. This had too much cereal for the sugar/pb mix so the next time I will cut back to 8 cups of cereal instead. I’ve only ever made or had these as a drop cookie, so the bar concept was new and faster, but I like the clusters better.
Amy Hudson
Made with half honey & half corn syrup. Definitely follow the suggestions to reduce cornflakes to 8 cups! Kids enjoyed them, but entirely to sweet for the grownups.
Jeremiah Evans
I substituted honey for corn syrup, doubled pb, honey and sugar. Used an entire 18oz box of cornflakes (I don’t eat normally so they would go to waste). Turned out perfect! I too have eaten these my entire life, mom made them whenever we went camping.
James Jones
These were great. Used the full 10 cups, but crushed it a little.
Jake Thompson
This was not good, no taste except the corn syrup. I threw it out. I can’t remember the last time I threw baking what a waste.
Frank Johnston
These are really yummy. I made these with 7 cups of cereal instead of 10, crunchy peanut butter and rainbow sprinkles on top. They’re just as described, like crispy treats except with cornflakes and peanut butter. I definitely would not use 10 cups of cereal as stated. Thanks for sharing this recipe.
