Step‑by‑Step Instructions for Chocolate Hazelnut Crunch Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is essential for achieving the perfect balance of chewiness and crunchiness in your Chocolate Hazelnut Crunch Cookies. Make sure to adjust oven racks to the middle position for even baking, and prepare a baking sheet by lining it with parchment paper to prevent sticking.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, use a hand mixer or stand mixer to cream together the softened unsalted butter, granulated sugar, and brown sugar. Beat this mixture on medium speed for about 3 to 5 minutes, or until it becomes light and fluffy, resembling a pale yellow cloud. This step is crucial for incorporating air into the dough, which will help your cookies rise beautifully.
Step 3: Incorporate Eggs and Vanilla
Next, add the large eggs one at a time, mixing well after each addition. Then, stir in the pure vanilla extract until everything is just combined. Allow the mixture to blend until it is creamy and smooth, ensuring that the eggs are fully incorporated to enhance the richness of the dough for your Chocolate Hazelnut Crunch Cookies.
Step 4: Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and a pinch of salt. Once combined, gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Be careful not to overmix, as this could lead to dense cookies. You want a soft dough that holds together well, ready for the exciting additions!
Step 5: Fold in Crunchy Components
Now it’s time to fold in the fun part! Gently add the chopped hazelnuts, semi-sweet chocolate chips, and crushed cornflakes into the dough. Use a spatula to carefully mix until all elements are evenly distributed, creating that delightful texture and flavor profile characteristic of Chocolate Hazelnut Crunch Cookies.
Step 6: Scoop and Bake
Using a tablespoon or cookie scoop, drop rounded amounts of dough onto the prepared baking sheet, spacing them about 2 inches apart to allow for spreading. Bake in the preheated oven for 10 to 12 minutes, keeping an eye on them—once the edges turn golden and the centers remain soft, they are ready to come out of the oven.
Step 7: Cool the Cookies
After baking, let the cookies cool on the baking sheet for 5 minutes. This allows them to set perfectly and develop that crispy edge. Then, carefully transfer them to a wire rack to cool completely. As they cool, your kitchen will be filled with the irresistible aroma of Chocolate Hazelnut Crunch Cookies!

Chocolate Hazelnut Crunch Cookies Recipe FAQs
What type of hazelnuts should I use for the cookies?
I recommend using toasted hazelnuts to enhance their nutty flavor! If you find raw hazelnuts, simply roast them in the oven at 350°F (175°C) for about 10 minutes, or until fragrant. Allow them to cool before chopping and adding them to your dough.
How long can I store Chocolate Hazelnut Crunch Cookies?
These cookies can be stored in an airtight container at room temperature for up to 1 week. To maintain their delightful crunch, ensure the container is tightly sealed. If you live in a humid environment, consider storing them in the fridge to keep them fresher for longer!
Can I freeze these cookies?
Absolutely! To freeze your Chocolate Hazelnut Crunch Cookies, lay them in a single layer on a baking sheet and freeze for about 1 hour. Once solid, transfer them to an airtight container or resealable bag, separating layers with parchment paper. They’ll keep well for up to 3 months. When you’re ready for a treat, pop them into a preheated oven at 350°F (175°C) for about 5 minutes to restore their texture.
My cookies turned out too flat. What went wrong?
If your cookies spread too much, it might be due to the butter being too warm or melted when mixing—be sure it’s softened but still cool. Additionally, check that your baking soda is fresh, as this is essential for the right rise. If possible, chill your dough for 30 minutes before baking to prevent excess spreading.
Are these cookies safe for people with nut allergies?
The primary ingredient for these cookies is hazelnuts, so they are not suitable for those with nut allergies. However, you can replace hazelnuts with seeds like sunflower or pumpkin seeds for a nut-free version. Just be cautious of cross-contamination if allergies are severe.
How can I enhance the flavor of my cookies?
To elevate the flavor profile of your Chocolate Hazelnut Crunch Cookies, use high-quality chocolate chips—dark chocolate adds a rich taste, while milk chocolate can lend a sweeter touch. Additionally, feel free to toss in a pinch of sea salt on top of each cookie before baking for a gourmet touch!
