Double Chocolate Hazelnut Cookies with Sea Salt

Why These Double Chocolate Hazelnut Cookies Became My New Favorite

I was supposed to be cleaning the house while my son napped, but my sweet tooth had other plans. Josh was out, so I raided my secret hazelnut stash and got to work. These double chocolate hazelnut cookies with sea salt turned out even better than I hoped. The combination of rich cocoa, crunchy hazelnuts, and a salty finish hit every note I was craving. They’re soft and chewy in the center with a slight crackle on top, exactly the kind of fudgy chocolate cookies I love.

3 Reasons You’ll Love These Soft and Chewy Chocolate Cookies

• The combination of Dutch-process cocoa and semi-sweet chips gives a deep, fudgy chocolate flavor that isn’t too sweet.
• Chopped hazelnuts add a satisfying crunch and a toasty note that pairs perfectly with chocolate.
• A sprinkle of sea salt on top balances the sweetness and makes each bite more complex.

Key Ingredients for Rich Chocolate Hazelnut Cookies

• Dutch-process cocoa gives these cookies a darker color and a smoother, less acidic chocolate flavor. If you only have natural cocoa, you can use it, but the cookies will be lighter and taste slightly more bitter.
• Hazelnuts: Toast them before chopping to bring out their nutty aroma. You can substitute with pecans or walnuts if needed.
• Sea salt: Use a flaky sea salt like Maldon for the best texture and pop of salt. Table salt will be too fine and may dissolve.

Kitchen Tools You’ll Need for These Cookies

• Electric mixer (stand or hand) for creaming butter and sugars
• Baking sheet, a heavy-duty one prevents over-browning
• Parchment paper or Silpat baking mat for easy release
• Cooling rack to let cookies set properly
• Cookie scoop for uniform size and even baking

Tips for Perfect Fudgy Chocolate Cookies Every Time

The key to soft and chewy chocolate cookies is pulling them from the oven when they still look slightly underdone in the center. They’ll continue to set on the hot baking sheet during the 3-minute rest. If you bake them until they look fully set, they’ll turn out cakey rather than fudgy. Also, make sure your butter is at room temperature so it creams properly with the sugars. That step builds the structure for a tender cookie.

Expert Tips for Bakery-Style Chocolate Hazelnut Cookies

For the best texture, toast the hazelnuts in a dry skillet over medium heat for 3-4 minutes until fragrant, then let them cool before chopping. This brings out their natural oils and deepens the nutty flavor. If your dough feels too soft to scoop, pop it in the fridge for 15-20 minutes, it will be easier to handle and the cookies will spread less.

Getting That Bakery-Style Crackle Top

The signature crackly top on these cookies comes from the high sugar content and the Dutch-process cocoa. For an even more pronounced crackle, roll each dough ball in a little granulated sugar before placing on the sheet. The sugar creates a thin crust that cracks as the cookie spreads in the oven. Also, make sure your oven is fully preheated, a hot oven sets the edges quickly, forcing the center to rise and crack.

Fun Variations on Chocolate Hazelnut Cookies

If you don’t have hazelnuts, chopped pecans or walnuts work just as well. For a different chocolate profile, try white chocolate chips or a mix of milk and dark. A teaspoon of instant espresso powder added to the dry ingredients will intensify the cocoa flavor without making the cookies taste like coffee. To make these gluten-free, substitute the all-purpose flour with a good 1:1 gluten-free baking blend, the rest of the ingredients stay the same.

How to Serve Sea Salt Cookies for Maximum Flavor

These sea salt cookies are great on their own, but a tall glass of cold milk or a scoop of vanilla ice cream turns them into a full dessert. For an afternoon treat, enjoy them with a cup of hot coffee or espresso, the bitterness balances the sweetness.

How to Store Your Double Chocolate Cookies

Store these cookies in an airtight container at room temperature for up to 5 days. To keep them extra soft, toss a slice of sandwich bread into the container, it will absorb excess air and release moisture. Replace the bread every couple of days.

Freezing Cookie Dough for Later

You can freeze either the baked cookies or the raw dough. For baked cookies, let them cool completely, then freeze them in a single layer on a baking sheet. Once solid, transfer to a freezer-safe bag for up to 3 months. For dough, scoop into balls, freeze on a sheet, then store in a bag. Bake frozen dough straight from the freezer, adding 1-2 minutes to the bake time.

Best Way to Reheat These Cookies

To bring back that just-baked softness, microwave a cookie for 10-15 seconds. If you prefer a slightly crisper edge, warm them in a 300°F oven for about 5 minutes. Don’t overheat or they’ll dry out.
