Step-by-Step Instructions for Chewy Cornflake Cookies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it’s warming up, line two baking sheets with parchment paper to keep the cookies from sticking. This will not only help with cleanup but will also ensure that your chewy cornflake cookies bake evenly.
Step 2: Whisk the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt, making sure everything is well combined. This step helps ensure that your dry ingredients are evenly distributed, which is crucial for the perfect texture in your cornflake cookies. Once mixed, set the bowl aside.
Step 3: Cream Butter and Sugars
In a large mixing bowl, take your softened salted butter and combine it with both brown sugar and granulated sugar using a hand mixer or stand mixer. Beat them together on medium speed for about 2-3 minutes until the mixture becomes light and fluffy, indicating that the sugars are well incorporated into the butter.
Step 4: Incorporate Egg Yolks and Vanilla
Next, add the egg yolks and vanilla extract to your butter-sugar mixture. Continue mixing on medium speed for another 1-2 minutes until the mixture appears pale and airy. This step is important for achieving that rich flavor and creamy texture in your chewy cornflake cookies.
Step 5: Combine Dry Ingredients
Gradually add the whisked dry ingredients to the wet mixture, mixing on low speed until just combined. Be careful not to overmix the dough; you want it to remain soft and slightly sticky. This adds to the chewy texture of your cornflake cookies.
Step 6: Fold in Oats and Cornflakes
Using a spatula, gently fold in the old-fashioned oats and cornflakes into the cookie dough. Make sure they are evenly distributed throughout so each cookie packs that delightful crunch. This is where the magic happens, turning ordinary dough into the star of your chewy cornflake cookies!
Step 7: Scoop the Dough
With a cookie scoop or tablespoon, drop dollops of dough onto the prepared baking sheets, spacing them about 2 inches apart. This allows for spreading as they bake. Aim for a uniform size to ensure even baking, guaranteeing that all your cookies are perfectly chewy.
Step 8: Bake to Perfection
Place the baking sheets in the preheated oven and bake the cookies for 10-12 minutes. For a chewy texture, aim for the shorter baking time, and watch for a light golden color on the edges. For a crispier finish, let them go for up to 12 minutes. Your kitchen will start to smell delightful!
Step 9: Cool and Finish
Once baked, remove the baking sheets from the oven and allow the cookies to cool on the sheet for about 5 minutes. This resting period helps them set perfectly. Don’t forget to sprinkle the warm cookies with flaky sea salt to elevate the flavors before transferring them to a wire rack to cool completely.

How to Store and Freeze Cornflake Cookies
Room Temperature: Store your cornflake cookies in an airtight container at room temperature for up to 4 days. This keeps them fresh and chewy while maintaining their delightful crunch!
Fridge: If you want them to last a bit longer, you can refrigerate the cookies for up to a week. Just be sure to use a container that seals tightly to preserve their texture.
Freezer: For longer storage, freeze your cornflake cookies! Place them in a freezer-safe container or a zip-top bag for up to 2 weeks. When ready to enjoy, simply let them thaw at room temperature.
Reheating: For a warm, fresh-out-of-the-oven taste, reheat cookies in a preheated oven at 350°F (175°C) for about 5 minutes. This brings back that lovely chewy texture!
Expert Tips for Chewy Cornflake Cookies
-
Spoon Flour Carefully: Always spoon flour into your measuring cup instead of scooping. This prevents excess flour that can lead to dry cornflake cookies.
-
Room Temperature Ingredients: Make sure your egg yolks and butter are at room temperature. This ensures better mixing and results in a creamier dough for softer cookies.
-
Don’t Overmix: Once you incorporate the dry ingredients, mix just until combined. Overmixing can lead to tougher cookies, losing that chewy texture you desire.
-
Use Parchment Paper: Lining your baking sheets with parchment paper prevents sticking and promotes even baking. No one wants to sacrifice a cookie because it clings to the pan!
-
Flavor Variations: Experiment with mix-ins like chocolate chips or dried fruits to add extra flavor dimensions. This keeps your cornflake cookies exciting for every occasion!
Make Ahead Options
These Chewy Cornflake Cookies are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 24 hours in advance by mixing all the ingredients together and chilling the dough in an airtight container. This not only saves you time during busy baking days but also enhances the flavors as they meld overnight. If you’re looking to store them longer, you can freeze the formed cookie dough balls for up to 3 months. When you’re ready to bake, simply take them out and allow them to thaw for about 30 minutes before placing them on parchment-lined baking sheets and baking as directed. This way, your cookies will turn out just as delicious, with that delightful crunchy texture every time!
