Chocolate Hazelnut Crunch Cookies Ingredients
For the Dough
- Unsalted Butter – Provides richness and moisture; substitute with salted butter, reducing added salt slightly.
- Granulated Sugar – Adds sweetness and browning; for deeper flavor, swap with coconut sugar.
- Brown Sugar (packed) – Contributes moisture and rich flavor; light brown sugar works well for a milder taste.
- Large Eggs – Binds the ingredients and adds moisture; can use flax eggs as a substitute for an egg-free version.
- Vanilla Extract – Enhances flavor complexity; almond extract is a nice alternative if desired.
- All-Purpose Flour – Provides structure; you can use gluten-free flour blends for a suitable substitute.
- Baking Soda – Acts as a leavening agent for a soft texture; ensure it’s fresh for optimal rise.
- Salt – Elevates flavors; skip if using salted butter or for low-sodium diets.
For the Mix-ins
- Chocolate Chips (semi-sweet or dark) – Adds the chocolatey goodness; substitute with white chocolate chips or a sugar-free alternative for variation.
- Chopped Hazelnuts (toasted) – Provides a nutty flavor and crunch; can be replaced with pecans or walnuts if needed.
- Crushed Cornflakes – Gives extra crunch; you can swap with crushed rice cakes or omit for a denser cookie experience.

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 is an important step as it ensures that your Chocolate Hazelnut Crunch Cookies bake evenly. While the oven warms up, prepare your baking sheets by lining them with parchment paper for easy cookie removal later.
Step 2: Cream Butter and Sugars
In a large mixing bowl, combine softened unsalted butter, granulated sugar, and packed brown sugar. Using an electric mixer on medium speed, beat the mixture until it turns light and fluffy, about 3 to 5 minutes. This creaming process is essential to create a tender and airy texture for your cookies.
Step 3: Add Eggs and Vanilla
Once your butter and sugars are well combined, add in the large eggs one at a time, mixing thoroughly after each addition. Follow this by incorporating the vanilla extract. Continue mixing until everything is fully combined and the mixture is smooth—this will infuse your dough with rich flavor.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together all-purpose flour, baking soda, and salt to combine. Gradually add this dry mixture to the wet ingredients, mixing just until a soft dough forms. Avoid overmixing at this stage to ensure your Chocolate Hazelnut Crunch Cookies remain tender and delightful.
Step 5: Fold in Crunchy Ingredients
Gently fold in the chopped toasted hazelnuts, chocolate chips, and crushed cornflakes using a spatula. This step adds the cookie’s signature crunch and rich flavors. Be careful not to overwork the dough—just mix until all ingredients are incorporated evenly.
Step 6: Scoop and Bake
Using a tablespoon, scoop rounded portions of cookie dough onto the lined baking sheets, making sure to space them about 2 inches apart. Bake in your preheated oven for 10 to 12 minutes, or until the edges are golden brown and the centers appear slightly soft. The waft of chocolate should start to fill your kitchen!
Step 7: Cool and Enjoy
Remove the cookies from the oven and let them cool on the baking sheets for about 5 minutes. This cooling time allows them to firm up. Then, transfer the cookies to a wire rack to cool completely. Your Chocolate Hazelnut Crunch Cookies are now ready to be savored!

How to Store and Freeze Chocolate Hazelnut Crunch Cookies
Airtight Container: Store your cookies in an airtight container at room temperature for up to one week to retain their freshness and delightful crunch.
Refrigerated Dough: If you want to prepare ahead, refrigerate the cookie dough for up to 2 days before baking. This not only saves time but also enhances the flavor!
Freezing Cookies: For longer storage, freeze baked cookies by placing them in a single layer on a baking sheet, then transferring to a resealable plastic bag after they are frozen. They can last up to 3 months.
Reheating: To enjoy the cookies warm again, simply pop them in a preheated oven at 350°F (175°C) for about 5–7 minutes, restoring their soft centers and crunchy edges perfectly!
Make Ahead Options
These Chocolate Hazelnut Crunch Cookies are perfect for meal prep enthusiasts! You can prepare the cookie dough up to 2 days in advance by mixing all the ingredients, storing it tightly wrapped in plastic wrap or an airtight container in the refrigerator. This helps the flavors meld while maintaining the dough’s quality. When you’re ready to bake, simply scoop the chilled dough onto a baking sheet and allow it to sit at room temperature for 10-15 minutes before baking for even better texture. If you prefer to freeze the dough, scoop it into balls and freeze individually for up to 3 months; just bake straight from the freezer, adding an extra minute or two to the baking time. Enjoy homemade cookies with minimal effort on busy weeknights!

Chocolate Hazelnut Crunch Cookies Recipe FAQs
What is the best way to choose ripe hazelnuts?
When selecting hazelnuts, look for those with a rich, brown color and a firm texture. Avoid any that are discolored or have dark spots, as these may indicate spoilage. Fresh hazelnuts should have a slightly sweet aroma.
How should I store my Chocolate Hazelnut Crunch Cookies?
Keep your cookies in an airtight container at room temperature for up to one week. This will help maintain their delightful crunch while preventing them from drying out. If you don’t have an airtight container, using a sealed plastic bag with the air squeezed out works well too.
Can I freeze Chocolate Hazelnut Crunch Cookies?
Absolutely! To freeze baked cookies, spread them in a single layer on a baking sheet and freeze until solid. Once firm, transfer them to a resealable plastic bag or airtight container. They can last up to 3 months in the freezer. When you’re ready to indulge again, pop them in a preheated oven at 350°F (175°C) for about 5-7 minutes to restore that fresh-baked taste.
What if my cookie dough is too sticky?
If your cookie dough is overly sticky, this may be due to the butter being too soft or too much moisture from the eggs. You can add an extra tablespoon of flour to the dough to help firm it up a bit. Remember, the dough should be soft but manageable; a slightly sticky texture is okay!
Are these cookies safe for dogs?
No, chocolate and certain nuts, including hazelnuts, can be harmful to dogs. Make sure to keep these tasty treats out of reach of your furry friends. If you’re looking for a dog-friendly treat, consider making a batch of plain peanut butter cookies just for them!
Can I substitute the butter with oil?
While you can use oil as a substitute for butter, doing so will alter the texture of your Chocolate Hazelnut Crunch Cookies, making them denser and possibly altering the flavor as well. For the best results, stick with butter or try using a butter substitute designed specifically for baking.
