I bake Double Chocolate Hazelnut Cookies when I want a treat that feels rich, comforting, and a little special without being hard to make.
The deep chocolate flavor, soft centers, and toasted hazelnuts make every bite feel bakery-worthy right from my own kitchen. They always disappear quickly once the tray cools.
My family loves these cookies for weekend baking, holiday platters, and after-dinner treats with a glass of milk. They look impressive, but the dough is simple and uses pantry basics with a few flavorful extras.
When I need a dependable chocolate cookie that feels memorable, this is one I gladly make again.
Why You’ll Love This Recipe
Double Chocolate Hazelnut Cookies are made for chocolate lovers. Cocoa powder and chocolate chips create a deep, rich flavor, while chopped hazelnuts add buttery crunch and balance. The contrast of soft cookie centers with crisp edges makes them especially satisfying.
These cookies are also very approachable for home bakers. The dough mixes in one bowl for dry ingredients and one bowl for wet ingredients, then comes together quickly with no complicated steps. You do not need special decorating skills or fancy equipment.
Another reason to love them is how flexible they are. Make them smaller for lunch boxes, larger for bakery-style cookies, or swap the chocolate chips to milk or dark chocolate. They are easy enough for everyday baking and special enough for sharing.
Serves: 24 people
This recipe makes about 24 medium cookies, depending on scoop size. If you make larger bakery-style cookies, expect about 16 to 18. They store well, which makes them great for gifting or enjoying through the week.
Ingredients You’ll Need
Dry Ingredients
- 1 3/4 cups all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon instant espresso powder (optional)
Wet Ingredients
- 3/4 cup unsalted butter, softened
- 3/4 cup brown sugar, packed
- 1/2 cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
Mix-Ins
- 1 cup semisweet chocolate chips
- 3/4 cup chopped toasted hazelnuts
Optional Add-Ins
- 1/2 cup white chocolate chips
- Flaky sea salt for topping
Use good-quality cocoa powder for the best chocolate flavor. Toasted hazelnuts bring a richer taste and better crunch than raw nuts. If you cannot find hazelnuts already skinned, rubbing warm toasted nuts in a towel helps remove loose skins.
Pro Tips
Toast the hazelnuts first
Toasting deepens their flavor and makes them crunchier. Let them cool before chopping and adding to the dough.
Measure cocoa carefully
Too much cocoa can dry out cookies. Spoon it lightly into the measuring cup and level it off.
Cream butter and sugar well
Beating the butter and sugars until light helps create softer cookies with better texture. Give this step a full 2 to 3 minutes.
Do not overmix after adding flour
Mix only until the flour disappears. Overmixing can make cookies tougher than needed.
Chill the dough if soft
If your kitchen is warm or the dough feels sticky, chill it for 20 to 30 minutes. This helps reduce spreading.
Use a cookie scoop for even size
Even portions bake more consistently and give a neater finished look. This is especially helpful when making multiple trays.
Tools You’ll Need
- Large mixing bowl
- Medium mixing bowl
- Hand mixer or stand mixer
- Measuring cups
- Measuring spoons
- Rubber spatula
- Baking sheets
- Parchment paper or silicone mats
- Cookie scoop or spoon
- Cooling rack
- Knife and cutting board for nuts
Having everything ready before you begin makes baking smoother and faster. It also helps prevent overmixing while searching for tools midway through the recipe.
Substitutions and Variations
Use Different Nuts
Swap hazelnuts for walnuts, pecans, or almonds. The cookies will still have great crunch and rich flavor.
Make Them Dairy-Free
Use plant-based butter and dairy-free chocolate chips. The cookies will still bake up soft and chocolatey.
Try Dark Chocolate
Use dark chocolate chips instead of semisweet for a deeper, less sweet cookie. This pairs beautifully with hazelnuts.
Add Extra Texture
Stir in shredded coconut or cacao nibs. These add interest without changing the core cookie too much.
Lighten the Sweetness
Reduce the granulated sugar slightly and use bittersweet chocolate chips. The cookies will still feel rich and balanced.
Make Ahead Tips
Double Chocolate Hazelnut Cookies are perfect for planning ahead because the dough stores very well. You can prepare the dough up to two days in advance, cover it tightly, and refrigerate until ready to bake. Chilling the dough can also deepen the chocolate flavor and help create thicker cookies.
If you like fresh cookies anytime, scoop the dough into portions first and place them on a lined tray. Freeze until firm, then transfer the dough balls to a freezer-safe bag. This makes it easy to bake a few cookies whenever you need them.
You can also bake the cookies ahead for parties or holiday trays. Once cooled, store them in an airtight container until serving time. They keep their flavor nicely and are easy to transport.
Instructions
Step 1: Prepare the Oven and Baking Sheets
Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper or silicone baking mats. This helps prevent sticking and supports even baking.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, baking soda, salt, and espresso powder if using. Stir until no cocoa lumps remain. Set the bowl aside.
Step 3: Cream the Butter and Sugars
In a large bowl, beat the softened butter, brown sugar, and granulated sugar with a mixer until light and fluffy, about 2 to 3 minutes. Scrape down the bowl as needed. This step helps create a tender cookie texture.
Step 4: Add Eggs and Vanilla
Beat in the eggs one at a time, mixing well after each addition. Add the vanilla extract and mix until smooth. The mixture should look glossy and fully combined.
Step 5: Add the Dry Ingredients
Add the dry ingredients to the wet mixture. Mix on low speed just until no dry streaks remain. Avoid overmixing so the cookies stay soft.
Step 6: Fold in Chocolate and Hazelnuts
Use a spatula to fold in the chocolate chips and chopped toasted hazelnuts. If using white chocolate chips, stir them in now as well. The dough will be thick and rich.
Step 7: Scoop the Dough
Use a cookie scoop or spoon to place portions of dough onto the prepared baking sheets, spacing them about 2 inches apart. If desired, press a few extra chocolate chips on top for a bakery-style look.
Step 8: Bake the Cookies
Bake for 10 to 12 minutes, or until the edges are set and the centers still look slightly soft. For crispier cookies, bake 1 to 2 minutes longer. Rotate pans halfway through if your oven bakes unevenly.
Step 9: Cool the Cookies
Let the cookies rest on the baking sheet for 5 minutes. Transfer them to a wire rack to cool completely. Sprinkle with flaky sea salt while warm if desired.
Serving Suggestions
Serve Double Chocolate Hazelnut Cookies with cold milk for a classic and simple pairing. The rich chocolate flavor balances beautifully with milk.
Add them to a dessert tray with fruit, brownies, or shortbread cookies. Their deep color and texture make them stand out nicely.
Enjoy one warm with coffee or tea in the afternoon. The toasted hazelnuts pair especially well with hot drinks.
Serve slightly warm with vanilla ice cream for an easy dessert. The soft cookie and cold ice cream are always a favorite combination.
Pack a few into lunch boxes or snack containers for a homemade treat. They hold up well and stay satisfying.
Wrap stacks of cookies in parchment and ribbon for thoughtful gifts. They travel nicely and feel special without much effort.
Leftovers and Storage
Once fully cooled, store the cookies in an airtight container at room temperature for up to five days. Place parchment paper between layers if stacking. They usually stay soft and flavorful very well.
To keep cookies extra tender, add a slice of bread to the container. The cookies absorb moisture from the bread while the bread dries out. Replace the bread as needed.
For longer storage, freeze baked cookies in a freezer-safe container for up to three months. Thaw at room temperature or warm briefly in the microwave for a fresh-baked feel.
You can also freeze unbaked dough balls and bake directly from frozen. Just add 1 to 2 extra minutes to the baking time.

Recipe FAQ
Can I use raw hazelnuts?
Yes, but toasting them first is strongly recommended. Toasting improves flavor and texture. It also helps loosen some of the skins.
Why did my cookies spread too much?
This often happens if the butter was too warm or the dough was not chilled. Too little flour can also cause spreading. Chill the dough for 20 to 30 minutes if needed.
Can I use dark chocolate chips?
Yes, dark chocolate chips work very well here. They create a deeper flavor and slightly less sweet cookie. Many people prefer them with hazelnuts.
Do I have to use espresso powder?
No, it is optional. Espresso powder does not make the cookies taste like coffee when used in a small amount. It simply deepens the chocolate flavor.
Can I freeze the dough?
Yes, cookie dough freezes beautifully. Scoop it first for easier baking later. Bake from frozen with a little extra time.
Why are my cookies dry?
Too much flour, too much cocoa, or overbaking are common reasons. Measure carefully and remove cookies when centers still look slightly soft. They finish setting as they cool.
Can I make them smaller?
Yes, use a smaller scoop or spoonful of dough. Reduce baking time by a minute or two and watch closely. Smaller cookies are great for sharing.
Conclusion
Double Chocolate Hazelnut Cookies are an easy homemade treat that feels rich, comforting, and dependable.
They combine deep chocolate flavor with crunchy hazelnuts in every satisfying bite.
Whether served warm from the oven or packed for later, they always feel special without being difficult.
Their soft texture, simple method, and classic flavor make them worth baking again and again.
