Ingredients You’ll Need

4 cups cornflakes cereal: These provide the delightful crunch and texture that make the cookies so special. Feel free to use any variety, but traditional cornflakes work best.
1 cup peanut butter: Choose smooth or crunchy based on your preference. Natural peanut butter can add a wonderful flavor, though it may change the texture slightly.
1/2 cup granulated sugar: This adds sweetness and helps bind the mixture together.
1/2 cup corn syrup: It acts as a sweetener and helps to keep the cookies chewy and cohesive. Light corn syrup is typically used, but dark corn syrup can add a deeper flavor.
1 teaspoon vanilla extract: This tiny amount adds a lovely depth to the peanut butter flavor.

How to Make Peanut Butter Cornflake Cookies

Heat the Mixture: In a saucepan, combine 1/2 cup granulated sugar and 1/2 cup corn syrup. Cook over medium heat, stirring until the edges start to bubble slightly, which should take about 5 minutes.
Add Peanut Butter & Vanilla: Remove the saucepan from heat and mix in 1 cup peanut butter and 1 teaspoon vanilla extract. Stir until the mixture is smooth and creamy.
Incorporate Cornflakes: Gently add 4 cups cornflakes cereal to the peanut butter mixture. Use a spatula to fold the flakes into the mixture, ensuring each flake is well-coated without crushing them.
Form Cookies: Use a spoon to scoop out spoonfuls of the mixture and drop them onto a parchment-lined tray. Aim for rounded mounds about the size of a tablespoon.
Let Cool: Allow the cookies to cool and set at room temperature. This will typically take about 15 minutes. Once they’re firm, they’re ready to enjoy!

Storing & Reheating

To keep your cookies fresh, store them in an airtight container at room temperature for up to a week. If you have leftovers, you can refrigerate them for up to two weeks. For longer-term storage, wrap them tightly and freeze for up to three months. To refresh the texture, allow them to sit at room temperature for a few minutes after thawing—they’ll be just as delicious!

Chef’s Helpful Tips

Avoid Overcooking: Be careful not to overheat the sugar corn syrup mixture; stop cooking as soon as it begins to bubble.
Mix Gently: When adding the cornflakes to the peanut butter mixture, stir gently to avoid crushing the flakes, which keeps your cookies crispy.
Ingredient Temperature: Make sure peanut butter is at room temperature; this ensures it incorporates smoothly with the other ingredients.
Experiment with Mix-Ins: Consider adding mini chocolate chips or dried fruits for an additional pop of flavor.
Make Ahead: These cookies are great for preparing in advance for parties or gatherings—just store them until you’re ready to serve.
