No Bake Peanut Butter Corn Flake Bars Recipe
It has been very warm here for the past week or so. Over 90° for an extended period of time has me whining. Western New York weather does not “do” 90s, and that is one of our best-kept weather secrets! Needless to say, I haven’t felt like turning on the oven to bake.
So, I dove deep into my recipe file for this old, old No Bake Peanut Butter Corn Flake Bars recipe as Hubby wanted a treat. This no-bake recipe is probably older than I am!
Variations for the corn flakes include using:
● Bugles
● Chex Mix
● Cocoa Puffs
● Life Cereal
● Popcorn
● Fritos
● Special K
Added toppings (or mixing into the mixture) include:
● Butterscotch Morsels (either as a drizzle or added whole)
● Candy Corn
● Peanuts
● M&Ms
● Marshmallows
● Semi-Sweet Chips (either as a drizzle or added whole)
Pretty much all the moose-mixes, chunky-bars and sweet n’ salty bar recipes you see these days started with this base recipe 50+ years ago! Just remember when you are adding your ingredients to work quickly as the sugar and corn syrup gets sticky and starts to set once you turn off that burner.
No Bake Peanut Butter Corn Flake Bars Ingredients:
● 1 cup Corn Syrup

● 1 cup Peanut Butter
● 5 cups Corn Flakes
No Bake Peanut Butter Corn Flake Bars Mise en Place:
● Measuring Cup

No Bake Peanut Butter Corn Flake Bars Directions:
● Set up all your ingredients first. This is very important because of how quickly this sets-up.
● Spray or lightly butter a 13″x9″ pan.
● In a large pot on the stove (large enough to hold all ingredients you are using), combine the corn syrup and sugar. Bring to a low boil stirring constantly. Boil 1 minute.
● Remove from heat; stir in peanut butter until smooth.
● Add corn flakes; mix well making certain all the corn flakes are well coated.
● Press corn flake mixture into your 13″x9″ pan. Tip: lightly butter your fingers or spatula (whatever you are using to press) before pressing the mixture into the pan.
● Cool completely before cutting.
● Optional: drizzle semi-sweet chips over the top.
● Note: if making these as cookies or balls, drop onto parchment paper.

I have never purchased corn syrup before, so I just googled it. On the Karo site they mentioned that their Lite syrup was not recommend for cereal bars. I’m assuming that it’s fine since that’s what’s in your photo, right? I want to make these with my kids this afternoon, and goodness knows we should be saving calories where we can!
Ann says
I don’t think I ever used anything else. I mean I must have, Stephanie, if they didn’t make light corn syrup 40+ years ago, but I don’t recall doing so. I wonder why they said not to? These harden after a few days, so maybe that is why? They don’t stay soft and chewy with the light? (just speculation here)
I doubt with kids that they will last a few days though. LOL

I must be living under a rock, not sure I have seen this recipe before! But now that you mention it, I do see how it is the base for so many other recipes! Thanks a ton for sharing! Great for not turning on the oven in the summer!

It just means you aren’t old, Mary. 😀

Too bad for us that hubby is allergic to corn 🙁
Ann says
Rice Krispies, Rhonda. The original Rice Krispies recipe was peanut butter, not marshmallows, and I’d be willing to guess it came about when Kellogg’s invented this recipe.
