Few homemade treats pair with coffee quite as perfectly as a batch of crisp, chocolate-studded biscotti. The combination of toasted hazelnuts and rich chocolate creates a cookie that feels indulgent while still maintaining the rustic charm that makes Italian baking so appealing. Every time I pull a tray from the oven, the aroma of roasted nuts and cocoa fills the kitchen and makes it difficult to wait for them to cool.
What I love most about chocolate hazelnut biscotti is how versatile they are. They are equally suited for breakfast with a cappuccino, an afternoon snack, or a simple dessert after dinner. Their crunchy texture makes them ideal for dipping, and because they store so well, they are one of my favorite make-ahead treats for busy weeks and holiday gatherings.
Why You’ll Love This Chocolate Hazelnut Biscotti Recipe
This recipe delivers the perfect balance of crunch and flavor. The toasted hazelnuts add a nutty richness while the chocolate provides deep, satisfying sweetness without overwhelming the cookie.
Another reason I return to this recipe often is its durability. Unlike soft cookies that lose freshness quickly, biscotti stay crisp for days when stored properly. That makes them perfect for gifting, entertaining, or simply keeping on hand for coffee breaks.
The recipe is also surprisingly straightforward. While biscotti require two baking sessions, the process itself is simple and rewarding. The extra baking time creates the signature crunch that makes biscotti so distinctive.
Ingredients
For the Biscotti
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- ¼ teaspoon salt
- ¾ cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- ½ teaspoon almond extract
- 1 cup toasted hazelnuts, roughly chopped
- ¾ cup dark chocolate chips or chopped dark chocolate
Optional Chocolate Drizzle
- 4 ounces dark chocolate, melted
- 1 teaspoon coconut oil or vegetable oil
Ingredient Notes
The hazelnuts are one of the stars of this recipe, so I always recommend toasting them before adding them to the dough. Toasting intensifies their flavor and brings out their natural sweetness. Even a few minutes in the oven can make a noticeable difference.
For the chocolate, I prefer using dark chocolate with a cocoa content between 60 and 70 percent. It provides rich flavor while balancing the sweetness of the dough. Chocolate chips work well, but chopped chocolate creates larger pockets of melted goodness throughout the biscotti.
Almond extract is optional but highly recommended. It complements the hazelnuts beautifully and adds an extra layer of flavor without overpowering the chocolate.

How to Make Chocolate Hazelnut Biscotti
Prepare the Oven and Baking Sheet
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking and make cleanup easier.
If your hazelnuts are not already toasted, spread them on a baking sheet and toast them for about 8 to 10 minutes. Allow them to cool before chopping.
Having all ingredients measured and ready before mixing helps the process move smoothly and efficiently.
Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, and salt. This helps distribute the leavening evenly and prevents clumps from forming in the dough.
Set the dry ingredients aside while preparing the wet ingredients. Separating these steps ensures a more evenly mixed dough later on.
The dry mixture should appear uniform and free of any visible lumps before moving forward.
Combine the Wet Ingredients
In a large mixing bowl, whisk together the sugar, eggs, vanilla extract, and almond extract until smooth. The mixture should become slightly lighter in color and well combined.
The eggs provide structure while helping bind all of the ingredients together. Taking an extra minute to whisk thoroughly contributes to a better texture.
Once mixed, the wet ingredients should look smooth and slightly glossy.
Make the Dough
Gradually add the dry ingredients to the wet mixture, stirring until a dough begins to form. The dough will be thicker and firmer than typical cookie dough.
Fold in the chopped hazelnuts and chocolate pieces until evenly distributed. Every slice should contain plenty of chocolate and nutty crunch.
The finished dough will feel somewhat sticky but should hold together well when shaped.
Shape the Logs
Transfer the dough onto the prepared baking sheet. Divide it into two equal portions and shape each into a log approximately 10 inches long and 3 inches wide.
Leave several inches of space between the logs because they will spread slightly during baking. Smooth the tops with lightly dampened hands if necessary.
Creating evenly shaped logs helps ensure consistent baking and uniformly sized biscotti slices.
First Bake
Bake the logs for 25 to 30 minutes or until lightly golden and firm to the touch. The tops should feel set, and the edges should begin developing a slight golden color.
Remove the baking sheet from the oven and allow the logs to cool for about 15 minutes. This cooling period makes slicing easier and prevents crumbling.
The logs should remain slightly warm but firm enough to handle comfortably.
Slice the Biscotti
Using a sharp serrated knife, slice the logs diagonally into pieces about ½ inch thick. A gentle sawing motion works best and helps prevent breakage.
Arrange the slices cut-side down on the baking sheet. The exposed surfaces will become beautifully crisp during the second bake.
Do not worry if a few crumbs fall away. Biscotti are meant to have a rustic appearance.
Second Bake
Return the sliced biscotti to the oven and bake for 10 minutes. Carefully turn each piece over and bake for another 10 minutes.
This second baking stage removes excess moisture and creates the signature crunch that biscotti are known for. For extra-crispy biscotti, add an additional few minutes of baking time.
Allow the biscotti to cool completely on a wire rack. They will continue to firm up as they cool.
Add the Chocolate Drizzle
If using the optional drizzle, melt the dark chocolate with the coconut oil until smooth. Drizzle it over the cooled biscotti using a spoon or piping bag.
Allow the chocolate to set before serving or storing. The drizzle adds extra richness and creates a bakery-style finish.
This final touch is optional, but it makes the biscotti especially attractive for gifting or entertaining.
My Best Tips for Success
Toasting the hazelnuts is one of the simplest ways to improve flavor. The extra step takes only a few minutes but significantly enhances the nutty character of the biscotti.
Use a serrated knife rather than a chef’s knife when slicing. The sawing motion creates cleaner cuts and reduces the likelihood of cracking.
Allow the biscotti to cool completely before storing. Trapped warmth can create condensation and soften the texture that makes biscotti so enjoyable.
Common Mistakes to Avoid
One of the most common mistakes is underbaking during the second bake. Biscotti achieve their signature crunch through this additional baking process, so it should not be rushed.
Adding too much chocolate can also create issues. While tempting, excessive chocolate can interfere with slicing and affect the structure of the cookies.
Slicing the logs too soon after the first bake can lead to crumbling. Allowing them to cool briefly creates cleaner slices and a more attractive finished product.
Flavor Variations
For a richer chocolate flavor, I sometimes add two tablespoons of cocoa powder to the dough. This creates a deeper chocolate profile while maintaining the classic biscotti texture.
Dried cherries make an excellent addition alongside the chocolate and hazelnuts. Their tartness provides a pleasant contrast to the sweetness of the cookie.
A touch of orange zest can also brighten the flavor and pair beautifully with both the chocolate and toasted nuts.
Serving Suggestions
Chocolate hazelnut biscotti were practically made for coffee. I love serving them alongside espresso, cappuccino, or strong brewed coffee for a classic Italian-inspired treat.
They are also delicious with hot chocolate during colder months. The crunchy texture softens slightly when dipped, creating an entirely different experience.
For entertaining, I arrange them on a dessert platter with fresh berries and chocolate truffles. The presentation feels elegant while requiring very little effort.
How to Store Chocolate Hazelnut Biscotti
Store the biscotti in an airtight container at room temperature. Properly stored, they remain fresh and crisp for up to two weeks.
For longer storage, they can be frozen for up to three months. Allow them to thaw at room temperature before serving.
Keeping moisture away is essential. Exposure to humidity can soften the biscotti and reduce the satisfying crunch that makes them special.
Frequently Asked Questions
Why Are My Biscotti Too Hard?

Do I Have to Toast the Hazelnuts?
While not absolutely necessary, toasting dramatically improves flavor and texture. I strongly recommend taking the extra step.
Can I Make These Without Nuts?
Yes. Simply omit the hazelnuts and replace them with additional chocolate or dried fruit.
How Long Do Biscotti Stay Fresh?
When stored in an airtight container, they typically remain crisp and delicious for up to two weeks.
