Peanut Butter Corn Flake Bars are one of those recipes that somehow sneaks its way into everyone’s recipe box. They’re just so good and so unbelievably easy to make! That makes this recipe an easy one to pass around and share.

I was first introduced to these bars by our housekeeper many years ago. She would often bring us a batch of them, much to my delight. After she moved on to other opportunities, I began making them myself when I needed a quick and easy treat for sharing or just when I had the craving.

You can skip the oven time for these bars. You’ll just need a few minutes of stovetop time to get things going, and then it’s just stirring and spreading the bars into a pan. I do suggest that you have everything measured and ready to go before you get started. That will make the simple preparation go quickly and easily.

I love the simplicity of these. It’s not just in their preparation, but in the flavor. It’s pretty much all about the peanut butter, with a light sweetness. The corn flakes add a nice texture and crunch, and provide some structure to help hold the bars together.

Ingredients

  • 1/4 cup (50g) packed light brown sugar
  • 1/2 cup light corn syrup
  • 1 teaspoon vanilla extract
  • 1 cup (255g) peanut butter
  • 3 cups crushed corn flakes*

Instructions

  1. Combine the brown sugar and corn syrup in a large saucepan over medium heat. Bring to a boil.
  2. Remove from heat and stir in the vanilla and peanut butter. Fold in the corn flakes until well mixed.
  3. Spread the mixture evenly in a 9″x 13″ pan. (Use a 9″x 9″ pan for thicker bars.) Chill until set (about 2 hours). Cut into squares.

Notes

*This is about 5-6 cups of whole corn flakes. They don't need to be finely crushed, but rather just enough not to have large pieces.

  1. Love all things peanut butter, but somehow have never heard of this recipe—what a great photo presentation!

  2. Thanks, JEP! As a fellow peanut butter lover, I encourage you to give these a try.

  3. Thanks for the recipe! I’ve never had these. Wonder how they’d be with chocolate on top? MMmmmm….

  4. Stacey, the addition of chocolate would certainly be interesting. Let me know if you try it!

  5. Wow.. these look really good. I’ve never eaten a dessert with cornflakes in it.. I’m definitely going to give it a try!

  6. Melanie, I highly recommend them. I hope you like them!

  7. Made these this morning and I have a quick question. I prepared these as written, with *3 cups crushed corn flakes* (measured after I crushed the cereal) and there seemed to be wa-ay too much crumbly corn flake bits. It makes me wonder if I should have used *3 cups corn flakes, crushed* (measure cereal first, then crush) instead. I think I used close to 6 cups of cereal (pre-crush). Your picture looks so good and creamy, mine – not so much… Ended up topping the whole thing off with a layer of melted dark chocolate chips in the hopes of holding everything together.

  8. Hi, Julie! It’s been ages since I made these, so I had to go back and do a little review. The amounts are correct in the recipe. I’m not sure what went wrong! It’s a very thick mixture when it gets mixed together. It should set up better as it cools.

  9. These look delicious. Could you use tahini or cookie butter
