Step‑by‑Step Instructions for Thick & Chewy Chocolate Chip Walnut Cookies
Step 1: Toast the Walnuts
Preheat your oven to 350°F (175°C). Spread the chopped walnuts evenly on a baking sheet and toast them in the oven for about 8-10 minutes, or until they are golden and fragrant. Keep an eye on them to avoid burning. Once toasted, allow the walnuts to cool before chopping them into smaller pieces if necessary.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, combine the softened unsalted butter, brown sugar, and granulated sugar. Use an electric mixer to beat the mixture on medium speed for 2-3 minutes, or until it becomes light and fluffy. This step is crucial for achieving the perfect texture in your Thick & Chewy Chocolate Chip Walnut Cookies.
Step 3: Add the Egg Mixture
With the mixer on low speed, add in the whole egg, egg yolk, and vanilla extract to the sugar-butter mixture. Mix until everything is well combined, scraping down the sides of the bowl as needed. The egg yolk will enrich the dough, ensuring that your cookies remain soft and chewy.
Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt. This step helps to evenly distribute the leavening agents and dry ingredients. Once mixed, gradually add the dry mixture to the wet ingredients in the large bowl, stirring gently until a soft dough forms.
Step 5: Combine Ingredients
Once the dough is starting to come together, gently fold in the semi-sweet chocolate chips and the toasted walnuts. Ensure that the mix-ins are evenly distributed throughout the dough. This balance of gooey chocolate and crunchy nuts is what makes the Thick & Chewy Chocolate Chip Walnut Cookies so delightful.
Step 6: Chill the Dough
To help the cookies maintain their shape while baking, use a large cookie scoop to portion the dough onto a parchment-lined baking sheet. Cover the dough with plastic wrap and chill it in the refrigerator for at least 30 minutes. This resting period allows the flavors to intensify and the dough to firm up.
Step 7: Bake the Cookies
Preheat your oven to 350°F (175°C) if it has cooled down. Place your chilled cookie dough balls on another parchment-lined baking sheet, leaving enough space between each. Bake for 11-13 minutes, or until the edges are golden and the centers are slightly underbaked. You’ll want to remove them when they still look soft.
Step 8: Cool the Cookies
Once baked, let the cookies rest on the hot baking sheet for about 5 minutes to set. Then, carefully transfer them to a wire rack to cool completely. This step ensures that the centers remain perfectly chewy while the edges have that lovely crispness that characterizes your Thick & Chewy Chocolate Chip Walnut Cookies.

Make Ahead Options
These Thick & Chewy Chocolate Chip Walnut Cookies are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the cookie dough up to 3 days in advance. Simply follow the recipe steps to mix your dough, then scoop it into balls and freeze them in an airtight container or a resealable bag. When you’re ready to bake, you can simply place the frozen dough directly on a baking sheet and add 1-2 minutes to the baking time for fresh, warm cookies just like homemade. Chilling the dough also enhances the flavors, ensuring your cookies are just as delicious as if made fresh on the spot!

Thick & Chewy Chocolate Chip Walnut Cookies Recipe FAQs
What type of walnuts should I use for the cookies?
Absolutely! I recommend using raw walnuts and toasting them yourself to enhance their flavor. Simply spread the chopped walnuts on a baking sheet and toast in a preheated oven at 350°F for 8-10 minutes. This step adds a rich, nutty profile that elevates your Thick & Chewy Chocolate Chip Walnut Cookies.
How should I store my cookies to keep them fresh?
To maintain their chewy texture, store your cookies in an airtight container at room temperature for up to one week. If you find they’re getting a bit stale, a quick microwave warm-up for about 10-15 seconds will revive their fresh-baked goodness beautifully!
Can I freeze the cookie dough?
Very! To freeze the dough, scoop your cookie dough balls onto a baking sheet lined with parchment paper. Freeze them for about 1-2 hours until solid, then transfer to a zip-top bag. The dough can be frozen for up to 3 months. When you’re ready to bake, simply preheat the oven and bake the frozen dough straight from the freezer, adding an extra 1-2 minutes to the baking time.
What’s the best way to ensure my cookies are chewy?
For thick and chewy cookies, I recommend slightly underbaking them. Remove the cookies from the oven when the edges are golden, but the centers still look a bit soft. Allow them to cool on the baking sheet for about 5 minutes; this lets them firm up while maintaining that delightful gooey center.
Are there any dietary considerations for these cookies?
If you have allergies or are baking for pets, it’s essential to consider the ingredients. Walnuts can be a common allergen for some, and chocolate is toxic for dogs. For a nut-free option, you can substitute the walnuts with seeds like sunflower or pumpkin seeds for a different yet tasty crunch!
How can I tell if my butter is the right consistency?
Great question! Use softened butter for this recipe. It should be slightly warm to the touch and malleable, but not greasy. If you press your finger into it, it should create an indentation without leaving a puddle of melted butter. This ensures your cookies will have the perfect texture!
