Ingredients You’ll Need

Ingredients:
- 1 cup granulated sugar
- 1 cup light corn syrup
- 1 cup creamy peanut butter
- 1/2 teaspoon vanilla extract
- 6 cups cornflake cereal

How to Make Cornflake Peanut Butter Cookies (No Bake) Recipe

Step 1: Heat Sugar and Corn Syrup

Begin by combining the granulated sugar and light corn syrup in a large saucepan over medium heat. Stir constantly as the mixture heats, paying close attention as it approaches a boil. Once those gentle bubbles begin to form, immediately remove the pan from the heat—this helps guarantee your cookies stay chewy instead of turning into hard candy.

Step 2: Stir in Peanut Butter and Vanilla

With the saucepan off the heat, add your creamy peanut butter and vanilla extract to the hot syrup. Stir it all together until smooth and creamy—the heat will help everything melt into a dreamy, fragrant base. This is when your kitchen really starts to smell incredible!

Step 3: Fold in the Cornflakes

Pour in all of your cornflake cereal and gently fold it into the warm peanut-buttery syrup. Use a big spoon or sturdy spatula, and work with care so you coat every flake but don’t crush them entirely. You want those iconic crunchy clusters in every cookie.

Step 4: Scoop and Shape

Working quickly, drop generous mounds of the mixture onto a parchment-lined baking sheet. You can use a spoon or a cookie scoop for uniform portions. If you want to finesse them, use slightly damp hands to shape each mound for a neater finish. The mixture will start to set as it cools, so a little speed here pays off.

Step 5: Cool and Set

Let the cookies cool at room temperature for about 30 minutes. As they rest, the glossy coating will firm up, transforming into chewy, crunchy perfection. Once they’re set, the Cornflake Peanut Butter Cookies (No Bake) Recipe is ready for snacking, gifting, or sneaking straight from the tray.

How to Serve Cornflake Peanut Butter Cookies (No Bake) Recipe

Garnishes

Elevate your cookies with a simple drizzle of melted chocolate or a sprinkle of flaky sea salt. If you have mini chocolate chips, gently press a few on top of each cookie right after shaping for extra flair and flavor. You can even finish them with rainbow sprinkles for a festive touch that’s perfect for parties.

Side Dishes

These cookies pair wonderfully with a tall glass of cold milk, a frothy cappuccino, or even a scoop of vanilla ice cream. For a cute dessert platter, team them up with other bite-sized no-bake treats or a refreshing fruit salad—everyone will want to try a bit of everything!

Creative Ways to Present

For a fun twist, stack two cookies with a schmear of marshmallow fluff or Nutella in between and make a “cookie sandwich.” You can also package a handful in cellophane bags tied with ribbon for easy gifting, or arrange them in cupcake liners on a decorative tray for an impressive, but effortless, display.

Make Ahead and Storage

Storing Leftovers

To keep your Cornflake Peanut Butter Cookies (No Bake) Recipe fresh, store them in an airtight container at room temperature. They’ll stay wonderfully chewy for up to a week (though they’ll likely disappear much faster!). Separate layers with parchment paper to prevent sticking.

Freezing

These cookies are freezer-friendly! Arrange in a single layer on a tray to freeze solid, then transfer to a freezer bag or airtight container. They’ll keep for up to three months; just let them stand at room temperature for a few minutes before enjoying.

Reheating

If you prefer your cookies slightly warm and gooey, pop one or two in the microwave for just five to ten seconds. Be careful not to overheat—just enough to recapture that fresh-from-the-pot texture!

FAQs

Can I use chunky peanut butter instead of creamy?

Absolutely! If you love a little extra crunch and peanut texture, chunky peanut butter works perfectly in the Cornflake Peanut Butter Cookies (No Bake) Recipe. Just be sure to mix it in thoroughly so the cookies hold together.

Do I have to use corn syrup?

The light corn syrup is key for keeping these cookies chewy and helping them set correctly. If you’re looking for substitutions, light honey can sometimes work, but the consistency and flavor may differ.

Can I make these gluten-free?

Yes! Just choose certified gluten-free cornflake cereal, and you can happily share these cookies with gluten-sensitive friends and family. All other ingredients are naturally gluten-free.

How do I prevent the cookies from sticking together?

Let the cookies cool and set completely before stacking. To be extra safe, layer parchment or wax paper between cookies in your storage container.

Can I double the recipe?

Certainly! The Cornflake Peanut Butter Cookies (No Bake) Recipe scales up beautifully—just use a big enough saucepan, stir well, and work quickly since the mixture does firm up as it cools.
