How to Make Peanut Butter Cornflake Cookies Recipe
Step 1: Prepare the Cornflakes
Start by measuring out 6 cups of cornflakes into a roomy mixing bowl. Take care not to crush them as you handle them because their crispy texture is essential to the final cookie experience. Setting them aside now means they’re ready to soak up that delicious peanut butter mixture later.
Step 2: Dissolve Sugar and Corn Syrup
Next, grab a medium saucepan and combine the corn syrup with sugar over medium heat. Stir occasionally and watch as the sugar dissolves completely into the syrup, forming a smooth and shiny mixture — this step makes sure your cookies bind perfectly without any graininess.
Step 3: Incorporate Peanut Butter and Vanilla
Once that syrupy mixture is ready, take it off the heat and whisk in the peanut butter along with the vanilla extract. Stir until the mixture is silky smooth and well combined, releasing the comforting aroma of peanut butter that makes these cookies absolutely crave-worthy.
Step 4: Combine Cornflakes with the Peanut Butter Mixture
Pour your warm peanut butter syrup over the cornflakes in the bowl. Using a rubber spatula or wooden spoon, gently fold the flakes until each one is generously coated. This is where the magic happens — coating every flake ensures every bite bursts with that perfect peanut butter flavor and satisfying crunch.
Step 5: Shape the Cookies
Now for the fun part: scoop small portions of the mixture onto a parchment-lined baking sheet, using either a cookie scoop or two spoons. Take a moment to gently flatten each mound with your spoon to form the classic cookie shape. Then let them cool completely so they firm up just right.
Step 6: Melt the Chocolate for Drizzling
While the cookies are setting, place the semi-sweet chocolate chips and vegetable oil in a microwave-safe bowl. Heat in short 15-second bursts, stirring in between, until the chocolate is fully melted and smooth. The oil helps make the drizzle glossy and easy to spread.
Step 7: Drizzle the Chocolate
When your cookies are firm, use a spoon to artistically drizzle the melted chocolate over each one. Allow this final layer to set at room temperature, transforming these crunchy peanut butter treats into elegant little delights that will impress everyone who tries them.
How to Serve Peanut Butter Cornflake Cookies Recipe

Garnishes
For an extra pop of texture and color, sprinkle a few crushed peanuts or additional cornflakes on top of the chocolate drizzle before it hardens. A light dusting of powdered sugar can also add a touch of festive charm for special occasions.
Side Dishes
These cookies shine on their own, but pairing them with a cold glass of milk or a cup of hot coffee or tea takes the experience up a notch. They’re also delightful alongside fresh fruit slices, balancing the richness with freshness.
Creative Ways to Present
Stack these cookies on a pretty platter tied with a rustic ribbon for gifting. Or arrange them in small mason jars for a charming homemade gift. For parties, individual cookie bags tied with twine always bring smiles and can double as take-home treats.
Make Ahead and Storage
Storing Leftovers
Store your peanut butter cornflake cookies in an airtight container at room temperature to keep their crunch intact for up to a week. Make sure they’re completely cooled and the chocolate drizzle has hardened before sealing the container.
Freezing
If you want to save these for later, freeze the cookies in a single layer on a baking sheet first, then transfer them to a freezer-safe container or bag. This prevents them from sticking together and helps maintain their shape. They’ll stay fresh for up to three months.
Reheating
No reheating needed for these cookies since they’re best enjoyed at room temperature for maximum crunch. If you prefer, let frozen cookies thaw at room temperature for about 15 to 20 minutes before serving—just enough time to enjoy them with their perfect crispness.
