Ingredients:
- White sugar
- Light corn syrup
- Butter
- Peanut butter
- Cornflakes cereal

Ingredient Notes & Substitutions
- Peanut butter: Creamy peanut butter is the best for homemade corn flake peanut butter cookies recipes, for a smooth mixture. If you want some extra texture, you’re welcome to make these cookies with crunchy peanut butter. Something to know about natural peanut butter: It’s sometimes too oily, so it might not set up as well.
- Cornflakes cereal: Cornflakes are the star of the show with these cookies. And you don’t have to buy name-brand. Trust me, the cheaper store brand tastes just as good in cookies. Maybe experiment with other cereals like crispy rice or even Cheerios for a different twist. But cornflakes are the classic for a reason.
- Light corn syrup: The “glue” that holds the cookies together for that yummy chewy texture. I don’t recommend substituting this with honey or maple syrup for this specific recipe because these cause the cookies to set differently.
- White sugar: The sugar gets dissolved with the corn syrup to create the ooey, gooey, sticky base that’s so mouthwatering. You’re basically making a quick candy syrup. Liquid sweetener won’t work here.
- Butter: For richness and flavor. You can use salted or unsalted butter, chef’s choice! If you use salted butter, it adds a very subtle sweet-and-salty kick. For dairy-free cookies, plant-based butter should work absolutely fine in this recipe.
How to make Corn Flake Peanut Butter Cookies:
Step 1. Line a waxed paper baking pan. A large cookie sheet lined with waxed paper or parchment paper is exactly what you need for this step.
Step 2. Cook the sugar and corn syrup over medium heat. Use a medium saucepan for this. Stir until the sugar dissolves and the mixture starts to gently bubble.

Step 3. Add together the butter and peanut butter. Once the sugar mixture starts to bubble, turn off the heat.

Step 4. Remove from the heat until mixed. Add your peanut butter and butter right into the hot saucepan. Stir until it’s all completely melted and smooth.

Step 5. Have your cornflakes ready in a very large mixing bowl. Place the cornflakes over the mixture with peanut butter. Carefully pour the hot peanut butter mixture over the cereal.

Step 6. Blend until the mixture coats the cornflakes. Cut the waxed paper by tbsp; slightly flatten if necessary. Using a spatula to gently fold and blend the mixture helps. You want every flake covered, but try not to crush the cereal. Work quickly on this step.

Step 7. Cool before serving. Let the cookies sit at room temperature for at least 30–60 minutes so they’ll set up and get firm.
Done! Enjoy your cookies!

Tips for Success
Be careful to not over-stir. Fold the mixture gently. Stirring too hard will break all the cornflakes into dust.
Use your fingers to slightly flatten the cookie if you want flat cookies. You can also leave them as drop cookies. A flat cookie is crunchy all the way through.
Be sure to completely combine the peanut butter and cornflakes.
It works best to heat the corn syrup and sugar first, then add in the peanut butter and butter.
Work fast. Once you add the peanut butter mixture to the cornflakes, it starts to set up quickly. Stir and scoop the cookies immediately.
Get full coverage. You want every flake to be covered, with no dry cereal left in the bowl.
Storage & Reheating
These no bake peanut butter cornflake cookies will need to be set completely, then they can be placed into an airtight container in a cool place. Cornflake cookies will stay fresh for up to two weeks.
Once they’re firm, you can put them in an airtight container in a cool place. Keep them stored at room temperature with layers of waxed paper between them. This keeps them from clumping up together.
