There's something magical about the combination of rich chocolate and toasted hazelnuts that instantly transports me to a cozy European café, even when I'm standing in my own kitchen. These decadent chocolate hazelnut cookies have become my signature holiday treat, and I'm absolutely thrilled to share this treasured recipe with you today.
Every December, my kitchen transforms into a cookie factory. Between the twinkling lights, festive music, and the aroma of chocolate wafting through the air, it's truly my happy place. But these particular cookies hold a special place in my heart. They remind me of the first Christmas I spent with my husband's family in Germany, where I discovered that hazelnuts aren't just an ingredient—they're a way of life.
What makes these cookies extra special is how they manage to be both sophisticated enough for your holiday cookie exchange and approachable enough for even beginner bakers. The dough comes together in one bowl (hello, less dishes!), the cookies hold their shape beautifully, and those festive sprinkles add just the right amount of Christmas cheer without being overwhelming.
Whether you're baking for Santa, gifting to neighbors, or simply treating yourself during the holiday season, these cookies deliver that perfect balance of fudgy chocolate flavor with delightful hazelnut crunch, all dressed up in their holiday best.

Ingredients You'll Need
Before we dive into the magic of cookie-making, let's talk about each ingredient and why it matters. Trust me, understanding your ingredients is the secret to baking success!
All-purpose flour (2 1/4 cups) forms the structural backbone of our cookies. I always use unbleached flour for its slightly nutty flavor that complements the hazelnuts beautifully. If you're measuring by volume rather than weight, make sure to spoon and level rather than scooping directly from the bag, which can add up to 25% more flour than intended.
Unsweetened Dutch-process cocoa powder (3/4 cup) is my go-to for these cookies. The Dutch-process variety has been alkalized, giving it a smoother, less bitter flavor and that gorgeous dark color that makes these cookies look incredibly rich. In a pinch, natural cocoa works, but your cookies will be lighter in color and have a more intense chocolate flavor.
Butter (1 cup, softened) should be at true room temperature—about 65°F. Too cold and it won't cream properly; too warm and your cookies will spread too much. I always cut mine into tablespoon-sized pieces and let it sit for 30-45 minutes before baking.
Hazelnuts (1 cup, toasted and chopped) are the star of this show! Toasting brings out their incredible nutty flavor and gives them a satisfying crunch. If you can't find hazelnuts, pecans or almonds work beautifully, but I urge you to seek out hazelnuts for that authentic European flavor.
Brown sugar (1 cup packed) adds moisture and that subtle caramel flavor that makes these cookies irresistible. I prefer dark brown sugar for its deeper molasses notes, but light brown works perfectly too.
Holiday sprinkles (1/2 cup) are where the fun comes in! I love using a mix of red, green, and white jimmies for classic Christmas colors, but feel free to get creative with your color combinations.
Cornstarch (2 teaspoons) is my secret weapon for the softest, thickest cookies. It prevents the proteins in the flour from developing too much, resulting in that tender, almost melt-in-your-mouth texture.
How to Make Decadent Chocolate Hazelnut Cookies with Holiday Sprinkles for Christmas
Toast and Prepare the Hazelnuts
Preheat your oven to 350°F (177°C). Spread the hazelnuts on a baking sheet and toast for 8-10 minutes, stirring once halfway through. You'll know they're ready when they're golden brown and fragrant. Immediately transfer to a clean kitchen towel and rub vigorously to remove most of the skins (don't worry if some stubborn ones stay on). Let cool completely, then chop into medium pieces—not too fine, as you want to taste those glorious nut chunks in every bite!
Mix the Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, cornstarch, baking soda, baking powder, and salt until completely combined and no lumps remain. This step is crucial—cocoa powder loves to clump, and nobody wants a bite of pure cocoa in their cookie! Set this mixture aside while you prepare the wet ingredients.
Cream Butter and Sugars
In a large bowl (or stand mixer fitted with the paddle attachment), beat the softened butter, granulated sugar, and brown sugar together on medium-high speed until light and fluffy—about 3-4 minutes. This step incorporates air into the butter, which helps create those perfectly thick cookies with tender centers. Don't rush this step! Properly creamed butter should be pale yellow and almost doubled in volume.
Add Eggs and Vanilla
Beat in the eggs one at a time, mixing well after each addition. Then add the vanilla extract and mix until combined. The batter should look smooth and slightly glossy. If it appears curdled, your butter was probably too cold—don't worry, the cookies will still taste delicious!
Combine Wet and Dry Ingredients
Reduce the mixer speed to low and gradually add the dry ingredients to the wet ingredients. Mix just until combined—overmixing leads to tough cookies. The dough will be quite thick, almost like brownie batter. This is exactly what we want for those fudgy centers!
Fold in the Mix-ins
Using a rubber spatula, gently fold in the chopped toasted hazelnuts and half of the chocolate chips (save the rest for pressing into the tops). Then fold in the holiday sprinkles, being careful not to overmix—too much stirring can cause the colors to bleed and make your cookies look muddy.
Chill the Dough
Cover the bowl with plastic wrap and refrigerate for at least 2 hours, or up to 3 days. Chilling is non-negotiable—it allows the flour to hydrate, the butter to firm up, and prevents the cookies from spreading too thin. If you're short on time, you can speed this up by placing the dough in the freezer for 30-45 minutes, stirring every 15 minutes.
Shape and Decorate
Once chilled, scoop the dough into 2-tablespoon portions (I use a medium cookie scoop) and roll into balls. Place on a parchment-lined baking sheet, leaving 2 inches between cookies. Press the remaining chocolate chips into the tops, then gently press additional sprinkles on top for that festive bakery look.
Bake to Perfection
Bake at 350°F (177°C) for 10-12 minutes. The cookies are done when the edges are set but the centers still look slightly underbaked—that's the secret to that fudgy texture! They'll continue to cook on the hot baking sheet after you remove them from the oven. Let cool on the baking sheet for 10 minutes before transferring to a wire rack to cool completely.
Expert Tips
Room Temperature is Key
All refrigerated ingredients should be at room temperature before mixing. Cold eggs can cause the butter to seize, resulting in dense cookies. Set everything out 30-45 minutes before you start baking.
Don't Skip the Chill
The dough must be thoroughly chilled before baking. Warm dough spreads too much, resulting in thin, crispy cookies rather than thick, fudgy ones. If your kitchen is warm, chill the shaped dough for 15 minutes before baking.
Underbake Slightly
These cookies taste best when slightly underbaked. They should look set around the edges but still soft in the center when you remove them from the oven. They'll firm up as they cool, giving you that perfect fudgy texture.
Prevent Color Bleeding
To keep your sprinkles looking vibrant, add them to the dough just before chilling, and press additional sprinkles on top right before baking rather than mixing them all into the dough.
Storage Success
Store these cookies in an airtight container with a slice of bread. The bread will become stale while the cookies stay soft and fresh for up to a week. Replace the bread slice every few days.
Freezing Tips
Both the dough and baked cookies freeze beautifully. Freeze dough balls on a baking sheet, then transfer to a freezer bag. Bake from frozen, adding 1-2 extra minutes. Baked cookies can be frozen for up to 3 months.
Variations to Try
White Chocolate Raspberry
Replace the chocolate chips with white chocolate chips and add 1/2 cup freeze-dried raspberries, crushed into small pieces. Use pink and red sprinkles for Valentine's Day.
Salted Caramel
Add 1/2 cup caramel bits to the dough and sprinkle the tops with flaky sea salt before baking. The sweet-salty combination is absolutely addictive!
Mint Chocolate
Add 1/2 teaspoon peppermint extract to the dough and use mint chocolate chips. Top with crushed candy canes instead of sprinkles for a festive touch.
Espresso Hazelnut
Dissolve 1 tablespoon instant espresso powder in the vanilla extract before adding to the dough. The coffee enhances the chocolate flavor without being overwhelming.
Orange Chocolate
Add 1 tablespoon orange zest and replace 1 teaspoon vanilla with orange extract. Use orange and brown sprinkles for Halloween or autumn celebrations.
Gluten-Free Version
Substitute the all-purpose flour with a 1:1 gluten-free baking blend. Add 1/4 teaspoon xanthan gum if your blend doesn't include it. The texture is just as amazing!
Storage Tips
These cookies are incredibly forgiving when it comes to storage, making them perfect for holiday gifting and make-ahead entertaining. Here's everything you need to know about keeping them fresh and delicious:
Room Temperature Storage: Once completely cooled, store cookies in an airtight container at room temperature for up to 7 days. For best results, place a slice of sandwich bread in the container with the cookies—the bread will become stale while the cookies stay soft and fresh. Replace the bread slice every 2-3 days for optimal freshness.
Refrigerator Storage: I don't recommend refrigerating these cookies as it can dry them out and make them tough. However, if you live in a very humid climate, you can refrigerate them in an airtight container for up to 5 days. Let them come to room temperature before serving for the best texture.
Freezing Baked Cookies: These cookies freeze beautifully! Place completely cooled cookies in a single layer on a baking sheet and freeze until solid (about 2 hours). Then transfer to a freezer-safe container or zip-top bag, separating layers with parchment paper. They'll keep for up to 3 months. Thaw at room temperature for 30-60 minutes, or warm in a 300°F oven for 5-7 minutes.
Freezing Cookie Dough: My favorite make-ahead option! Scoop the dough into balls and freeze on a baking sheet until solid, then transfer to a freezer bag. The dough will keep for up to 3 months. Bake from frozen, adding 1-2 extra minutes to the baking time. You can also freeze the entire batch of dough and thaw overnight in the refrigerator when ready to bake.
