The Best Double Chocolate Chip Cookies Recipe

Y’all, these cookies are incredible. They are decadent yet balanced, offering a deep cocoa flavor that satisfies your chocolate cravings without being overwhelming. Every bite is filled with generous chunks of chocolate chips that melt into pools of gooey goodness, creating pockets of pure indulgence throughout the cookie.

The hazelnuts, however, are what set these cookies apart. I just love the how hazelnut and chocolate pairs together! Roasted to perfection while baking, the hazelnuts add a delightful crunch and a nutty depth that elevates the entire cookie experience. Each bite of these double chocolate chip cookies is a harmonious blend of textures that make these cookies so addicting. If you’re not a huge hazelnut person, feel free to substitute with your favorite nuts or you can forgo putting nuts in this recipe altogether. Your house, your rules!

What Ingredients are Needed for these Double Chocolate Chip Cookies?

Dark Brown Sugar: Dark brown sugar plays an important role in this chocolate chip cookie recipe. Dark brown sugar contributes to the rich, caramel-like flavor of the cookies and provides additional moisture, which aids in getting the perfect chewy texture for these cookies.

Granulated Sugar: Granulated sugar helps spread the cookie and promotes a tender, crisp texture. Using brown sugar and granulated sugar together creates the perfect cookies that are chewy in the middle and lightly crisp on the edges.

Butter: Provides additional moisture to the cookies, which helps with its chewy texture.

Eggs: this cookie recipe uses a whole egg and an additional egg yolk, which contributes to the chewy texture.

Flour: We are using all-purpose flour to form the base of the cookie dough. However, if you need these cookies to be gluten-free I recommend using a 1 to 1 all-purpose gluten-free flour. KING ARTHUR and CUP 4 CUP are two great options. I also include tips on measuring flour below, which will ensure your cookies do not turn out dry or crumbly.

Baking Soda and Powder: Baking soda and baking powder helps with leveling the cookies and aids in their texture. The combination of these two compounds ensure a chewy cookie with a tender crumb.

Chocolate Chips: I prefer semi-sweet chocolate chips, and I use a heaping cup, as I want to have chocolate in every bite of these cookies.

Cocoa Powder: Adds chocolatey depth to these cookies and gives these cookies their color.

Hazelnuts: adds crunch and a deep nutty flavor to these cookies.

Vanilla Extract: This recipe uses pure vanilla extract to add that delicious vanilla flavor.

Salt: Salt (yes, salt) is key to any dessert. Adding salt to your dessert helps with balancing the flavors. Trust me, don’t skip with step. I also add some to the top, which I think works well with the hazelnuts.

How to Make Double Chocolate Chip Cookies

Step 1: In a medium mixing bowl, sift the flour, baking soda, cocoa powder, baking powder, and salt. Mix and set aside.

Step 2: In a medium-large mixing bowl, add the granulated sugar, dark brown sugar, butter, and vanilla and beat with a hand mixer for about 2 minutes.

Step 3: Add the egg and yolk. Beat for an additional 1 minute. Your mixture should be shiny.

Step 4: Next, add your “sifted flour-cocoa powder mixture” into your wet ingredients and mix with a wooden spoon or rubber spatula until well combined. Be sure not to over mix.

Step 5: Then, add your chocolate chips and hazelnuts to the dough and carefully fold them in until incorporated.

Step 6: Next, transfer the cookie dough to a fridge and let chill for at least 30 minutes to allow the flour to hydrate and obtain that vanilla flavors (Pro tip: Allowing your dough to refrigerate for 2-4 hours will result in the best flavored cookie; however, 30 minutes works just fine. Not allowing your cookie to rest in the refrigerator at all will not result in optimal flavor or texture.)

Step 7: Remove your chilled dough and preheat your oven to 350°F. Line a nonstick baking sheet with parchment paper.

Step 8: Use a large cookie scoop (3 tablespoons cookie scooper) to scoop the dough and place the dough onto a parchment lined baking sheet. The dough should be about 3 inches apart.

Step 9: Bake the cookies at 350 degrees for 13-16 minutes and top with flaky sea salt as soon as you take them out of the oven to cool. Let rest for about 10-15 minutes and enjoy!

Tip & Tricks for the Best Double Chocolate Chip Cookies

Chill your dough before baking your cookies. Chilling the dough will hydrate the flour and will produce cookies with a thicker texture and enhanced flavor. I recommend that you let you dough chill for at least 30 minutes, but if you have time, 2-4 hours of refrigeration will render the best flavor.
Be sure to use room temperature eggs.
You want to cream your sugar with your butter (i.e., beat with a mixer for 2 minutes), which requires your butter to be room temperature. Creaming your butter will ensure you have the best texture.

How to Measure Flour for These Cookies?

Use the Correct Measuring Cup: Use a dry measuring cup. These cups typically come in sizes like 1 cup, 1/2 cup, etc.
Fluff the Flour: Before measuring, fluff up the flour in the bag or container using a spoon. This helps prevent compacting and ensures a more accurate measurement.
Spoon into the Cup: Gently spoon the fluffed-up flour into the measuring cup, allowing it to pile up above the rim.
Level Off: Use a flat edge, like the back of a knife, to level off the excess flour from the top of the measuring cup. Do this without tapping or shaking the cup to avoid settling.

Can I Freeze These Cookies

Yes! Freezing cookies is my favorite way to ensure I always have a sweet treat on hand. Here’s how:

Shape the Dough: After preparing the cookie dough, scoop your dough into balls.
Place in Gallon Freezer-Safe Bag: Carefully, place the portioned balls in a gallon-size freezer bag. Make sure it is well-sealed to prevent air and moisture from reaching the dough.
Use an Airtight Container: If you prefer, you can place the wrapped cookie dough in an airtight container instead of using a gallon bag.
Label and Date
Store in the Freezer for up to 3 months.
Bake When Ready to Use. When you’re ready to bake, simply remove the cookie dough from the freezer, let it thaw slightly if needed, and follow the original baking instructions. Note: You may need to add 2-3 minutes to the bake time to account for the frozen dough.

How long do double chocolate chip cookies last?

On the rare chance you have leftovers, you can store them in an airtight container at room temperature for up to 5 days.

Can this recipe be made gluten-free?

Yes, I recommend using a 1 to 1 all-purpose gluten-free flour.
