Ingredients You’ll Need

• Cornflakes Cereal: These form the crunchy backbone of the cookies; try not to crush them so you get that signature crispy texture.
• Corn Syrup (Light): Helps bind everything together and lends that lovely chew—essential for the perfect no-bake cookie. If you dislike corn syrup, see substitutions below!
• Sugar: Adds sweetness and helps set the cookie. Don’t skip, or they won’t firm up properly.
• Peanut Butter: The creamy, dreamy hero of this treat. Opt for smooth peanut butter for the best texture.
• Vanilla Extract: Adds a gentle warmth and rounds out the flavors.
• Semi-Sweet Chocolate Chips: For drizzling over the top; brings a touch of chocolate that really makes these cookies pop.
• Vegetable Oil: Mixed with the chocolate to keep the drizzle smooth and glossy.

Variations

There’s plenty of room to play here:

• Nutty Twist: Try swapping peanut butter for almond or cashew butter. Each adds its own unique richness.
• Salty Sweet: Toss in a handful of salted peanuts or pretzels for extra crunch.
• Festive Flair: Add colorful sprinkles or swap the chocolate drizzle for white chocolate—perfect for holidays and birthdays.
• Dairy-Free: Use a plant-based butter and dairy-free chocolate chips to make these cookies vegan-friendly.
• Less Sweet: Reduce the sugar slightly, or pick a natural sweetener like honey or brown rice syrup if that’s your preference.

How to Make Peanut Butter Cornflake Cookies

Step 1: Prepare Your Cornflakes

Start by measuring your cornflakes into a large bowl. Handle with care—a gentle hand keeps them crunchy, which is what you want!

Step 2: Make the Syrup Mixture

In a medium saucepan over medium heat, combine your corn syrup and sugar. Stir occasionally and watch closely. Once the sugar is fully dissolved (the liquid should look clear), remove from the heat.

Step 3: Add Peanut Butter and Vanilla

Immediately stir in the peanut butter and vanilla extract. Mix well—it should come together into a glossy, dreamy blend.

Step 4: Combine with Cornflakes

Pour this warm peanut butter mixture over the cornflakes. With a spatula or wooden spoon, gently fold everything together. Each flake should get well coated but stay mostly intact.

Step 5: Shape the Cookies

Scoop out portions of the mixture (a cookie scoop or two spoons work perfectly) onto a parchment-lined baking sheet. Flatten each slightly so they look like classic cookies. Let these cool at room temperature—they’ll firm up as they cool.

Step 6: Add the Chocolate Drizzle

While your cookies are setting, combine the chocolate chips and vegetable oil in a microwave-safe bowl. Microwave in 15-second bursts, stirring between each, until silky smooth. Drizzle this over the hardened cookies using a spoon. Let the chocolate set, then they’re ready to serve.

Pro Tips for Making the Recipe

• Don’t Rush the Syrup: Wait for the sugar to fully dissolve before adding peanut butter; undissolved sugar can make the texture gritty.
• Gentle Folding: The less you crush your cornflakes, the lighter and crunchier the cookies will be.
• Drizzle Like a Pro: For neat chocolate lines, use a fork or a zip-top bag with a small snip in the corner.
• Cooling Counts: Let them cool completely to set—if you’re in a hurry, pop the tray in the fridge for a bit.

How to Serve

These cookies truly shine on their own, but they’re also fun to dress up:

• Snack Attack: Serve them fresh for after-school treats, midnight snacks, or coffee breaks.
• Dessert Platter: Add them to a plate with brownies, fudge, or fruit slices for a party tray.
• Ice Cream Sandwiches: Try sandwiching a scoop of vanilla ice cream between two cookies for pure bliss.
• Holiday Swap: They’re a hit at cookie exchanges and travel beautifully in lunchboxes or holiday tins.

Make Ahead and Storage

Storing Leftovers

Once the cookies and chocolate drizzle are fully set, transfer them into an airtight container. Layering with wax or parchment paper helps prevent sticking. At room temperature, they’ll stay fresh and delicious for up to a week.

Freezing

Want to keep a stash on hand? Freeze the cooled cookies in a sealed container for up to two months. Just let them thaw at room temperature before eating; they’ll taste just as good as the day you made them.

Reheating

No reheating is necessary. These are made to be enjoyed as-is, but if you want them slightly warm, a quick 5-second spin in the microwave will do.

FAQs

Can I use natural peanut butter instead of regular?
Yes, you can, but keep in mind that natural peanut butter tends to be oilier and runnier than standard varieties. Stir it very well before measuring, and know that your cookies may be a bit softer—but still entirely delicious.

What if I don’t have corn syrup?
No problem! You can substitute with honey or brown rice syrup for a slight difference in flavor (and sweetness). Note that honey may make the cookies a little stickier and give a more pronounced flavor.

My cookies aren’t setting—what happened?
This most often happens if the sugar didn’t fully dissolve in the syrup mixture or if there was too much liquid. Double check that you simmer the syrup until smooth, and don’t add extra peanut butter, which can change the texture.

Are these cookies gluten-free?
If you use certified gluten-free cornflakes, yes! Always double check brands and labels to be sure.
