When my pastry teacher first demonstrated how to make a chocolate hazelnut tart, I was skeptical. The combination seemed too rich, too decadent for everyday enjoyment. How wrong I was! Ten years and countless iterations later, this Chocolate Hazelnut Tart has become my signature dessert—the one friends request for birthdays, the dessert that disappears first at potlucks, and my personal comfort food on those days when only chocolate will do.
What makes this tart special isn’t just the ingredients, though they are exceptional. It’s the perfect balance between textures and flavors that creates something greater than the sum of its parts. The contrast between the crumbly, nutty base and the smooth, silken filling creates a sensory experience that lingers long after the last crumb has been devoured. I’ve served this tart at casual backyard gatherings and formal dinner parties alike—it has a remarkable ability to feel simultaneously rustic and sophisticated. Whether you’re an experienced baker or trying your hand at tarts for the first time, this recipe welcomes you with open arms and forgives small imperfections, which only add to its charm.
What You’ll Need
For this irresistible chocolate-hazelnut creation, gather these carefully selected ingredients:
For the Buttery Hazelnut Crust
- 2 cups toasted hazelnuts, with 1/4 cup reserved for garnishing
- 1/2 cup all-purpose flour
- 1/4 cup granulated sugar
- A small pinch of salt
- 1/2 cup cold unsalted butter, diced into small cubes
- 2 teaspoons pure vanilla extract
- Ice water (about 2-3 tablespoons, as needed)
For the Velvety Chocolate Filling
- 1 cup premium hazelnut spread
- 1/2 cup heavy whipping cream
- 2 tablespoons cornstarch
- 1 teaspoon vanilla extract
- Pinch of salt
- 1 cup high-quality dark chocolate chips
- 1/2 cup additional heavy cream
- 1 tablespoon hazelnut paste (optional for enhanced flavor)
Kitchen Arsenal: Tools You’ll Need
Before diving into the creation process, let me share my kitchen must-haves for crafting this tart with minimal fuss:
- 9-inch Tart Pan with Removable Bottom: This is non-negotiable. The removable bottom ensures you can display your creation without damaging that beautiful crust.
- Heat-Safe Mixing Bowls: I prefer glass bowls for melting chocolate—they distribute heat evenly and allow you to see exactly what’s happening with your ingredients.
- Food Processor: Trust me, trying to chop hazelnuts finely by hand is an exercise in patience you don’t need. A good processor transforms them into the perfect texture in seconds.
- Silicone Spatula: The unsung hero of baking. It gets every last bit of that precious hazelnut chocolate filling from the bowl to the tart.
- Whisk: Essential for achieving that silky-smooth ganache without unwanted lumps.
- Measuring Tools: Precision matters in baking, especially with something as balanced as this tart.
- Microplane or Zester: For adding those elegant chocolate curls on top that elevate the presentation.
- Cooling Rack: Allows your tart to cool evenly, preventing moisture from building up underneath.
- Offset Spatula: My secret weapon for spreading fillings with professional precision.
I’ve found having everything ready before starting makes the process flow much more smoothly. There’s nothing worse than hunting for your spatula with chocolate-covered hands!
Creating The Perfect Tart: Step-by-Step Instructions
Now comes the fun part! Let me walk you through the process of creating this decadent chocolate hazelnut masterpiece from start to finish. The magic of this tart lies not just in the quality ingredients, but in the technique and timing that brings everything together.
Crafting The Nutty Base
- Toast Those Hazelnuts to Perfection: Begin by preheating your oven to 300°F. Spread 1½ cups of the hazelnuts (saving the remaining ½ cup for later) on a parchment-lined baking sheet in a single layer. Toast them for 8-10 minutes until they’re fragrant and their skins begin to crack. Watch carefully—they can go from perfectly toasted to burnt in moments! Once done, wrap them in a clean kitchen towel and rub vigorously to remove most of the skins.
- Create Your Crust Mixture: Allow the hazelnuts to cool completely before transferring them to your food processor. Add the flour, sugar, and salt, then pulse until the nuts are finely ground and the mixture resembles coarse sand. The texture should be uniform but not so processed that it becomes oily.
- Incorporate the Butter: Add the cold butter cubes and vanilla extract to your food processor and pulse in short bursts until the mixture resembles wet sand with some pea-sized butter pieces still visible. This creates those beautiful flaky pockets in your finished crust!
- Add Just Enough Moisture: With the processor running, drizzle in ice water one tablespoon at a time just until the dough begins to come together. You’ll know it’s ready when you can pinch some between your fingers and it holds together without being sticky.
- Form and Chill the Crust: Turn the dough out into your tart pan and press it evenly across the bottom and up the sides using your fingertips. Don’t worry about making it perfect—that rustic quality is part of its charm! Pierce the bottom several times with a fork, then place in the freezer for 15-20 minutes to firm up while you preheat your oven to 350°F.
- Blind Bake to Golden Perfection: Line your chilled crust with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes, then carefully remove the weights and parchment and return to the oven for another 10-12 minutes until the edges are golden and the center is dry to the touch. Allow the crust to cool completely before filling.
Creating The Luxurious Filling
Now that our crust has cooled, it’s time to create the star of the show—that irresistible chocolate-hazelnut filling that makes this tart so memorable.
- Prepare Your Hazelnut Base: In a medium bowl, whisk together the hazelnut spread, 1/2 cup of heavy cream, cornstarch, vanilla extract, and salt until completely smooth and silky. Take your time with this step—those few extra minutes of whisking will reward you with a perfectly velvety texture.
- Add Lightness and Air: In a separate chilled bowl, whip the remaining heavy cream until soft peaks form. Using a rubber spatula, gently fold about one-third of the whipped cream into your hazelnut mixture to lighten it. Then fold in another third, being careful not to deflate the air you’ve worked so hard to incorporate. Reserve the final third for garnishing later.
- Fill Your Waiting Crust: Pour this heavenly mixture into your cooled tart shell, using an offset spatula to smooth it into an even layer. Tap the pan gently on the counter a few times to release any air bubbles that might be trapped beneath the surface.
Creating The Glossy Ganache Topping
The final layer brings everything together with its shiny finish and deep chocolate flavor:
- Heat With Precision: In a small, heavy-bottomed saucepan, heat the remaining 1/2 cup of heavy cream just until you see tiny bubbles forming around the edges—don’t let it come to a full boil! Immediately remove from heat.
- Create Silky Chocolate Magic: Scatter your dark chocolate chips into the hot cream and add the hazelnut paste if using. Let stand untouched for 2 full minutes—patience is key here! This allows the chocolate to melt evenly without any risk of seizing. After waiting, gently stir with a silicone spatula in one direction until utterly smooth and glossy. If any stubborn pieces remain, return to low heat for just 5-10 seconds.
- The Artist’s Touch: Wait until your ganache has cooled slightly but is still pourable (about 5 minutes). Then, starting from the center, pour it over your hazelnut filling in a steady stream, tilting the tart as needed to create an even coating. The ganache should naturally settle into a mirror-like surface.
- The Final Rest: Transfer your masterpiece to the refrigerator and let it set for at least 3 hours, though overnight is even better if you can resist the temptation! This resting time allows all the flavors to meld together perfectly.
Planning Ahead: Make-Ahead Tips and Storage Secrets
One of the things I love most about this Chocolate Hazelnut Tart is how brilliantly it works with a busy schedule. I’ve developed these strategies through years of holiday baking marathons and last-minute dinner party preparations:
Prep Now, Impress Later
- The Crust Can Wait: The hazelnut crust dough can be prepared up to 3 days ahead and stored in the refrigerator. Simply wrap it tightly in plastic wrap, pressing it into a disk rather than the tart pan. When you’re ready to bake, let it sit at room temperature for about 20 minutes to soften slightly before pressing into your pan. The crust can even be fully baked a day ahead—just cover loosely with foil once cool and store at room temperature.
- Ganache Gets Better with Time: The chocolate ganache actually develops a deeper flavor when made 1-2 days ahead! Store it in an airtight container in the refrigerator, then warm it gently in 15-second microwave intervals, stirring between each, until it reaches spreading consistency. This slow warming prevents the chocolate from seizing or becoming grainy.
- Fully Assembled Magic: The complete tart can be assembled up to 2 days before serving—in fact, I often prefer making it the day before a special occasion. The flavors meld beautifully during an overnight rest in the refrigerator, and the texture becomes perfectly set. Plus, it’s one less thing to worry about on the day of your gathering!
Keeping Your Tart Perfect
For the best quality and flavor retention, follow these storage guidelines:
- Room Temperature: This tart can remain at room temperature for up to 8 hours if your kitchen isn’t too warm. The ganache will soften slightly, creating an even more luscious mouthfeel.
- Refrigerator Storage: Store leftovers in the refrigerator, covered with a cake dome or loosely tented with foil (avoiding direct contact with the ganache surface). It will keep beautifully for up to 5 days, though the crust may soften slightly over time.
- Freezer Friendly: Yes, you can freeze this tart! After it’s completely set, wrap it carefully in plastic wrap, then aluminum foil, and freeze for up to 1 month. Thaw overnight in the refrigerator before serving. The texture remains remarkably good, though the ganache might lose a bit of its shine.
- Serving From Cold: When serving from the refrigerator, I like to let slices sit at room temperature for about 15-20 minutes—this brings out the full depth of the chocolate and hazelnut flavors that can be slightly muted when too cold.
Pro Secrets: Mastering Your Chocolate Hazelnut Tart
Over the years, I’ve collected little tricks that elevate this tart from delicious to unforgettable. Here are my hard-earned secrets for creating a tart that looks and tastes like it came from a high-end patisserie:
The Perfect Hazelnut Roast
Temperature control is everything when toasting hazelnuts. I’ve found that a lower temperature of 325°F for 12-15 minutes yields better results than a quick, hot roast. This slower approach develops deeper flavor compounds without risking burnt edges. Your kitchen should fill with a rich, nutty aroma—that’s when you know they’re perfectly done. For even more depth, add a tiny pinch of espresso powder to the nuts before toasting—it’s undetectable as coffee but magically enhances the nuttiness.
The Failproof Crust Technique
After countless tarts, I’ve learned that the temperature of your hands matters when pressing in the crust. If your hands run warm like mine, chill them with cold water first or use the back of a measuring cup wrapped in plastic wrap to press the dough evenly. Always, always work from the center outward in a circular motion. This prevents the dreaded thick-center-thin-edges problem that leads to uneven baking.
Silky-Smooth Filling Success
The secret to that restaurant-quality smooth filling? Temperature harmony. All your ingredients—especially the hazelnut spread and cream—should be at the same temperature before combining. I take everything out 30 minutes before mixing. And here’s something most recipes won’t tell you: after mixing, tap the bottom of your bowl firmly against the counter several times to release any trapped air bubbles that could disrupt that perfect silky texture.
The Cooling Game-Changer
Patience transforms this tart from good to extraordinary. After chilling for at least 4 hours, I let the tart sit at room temperature for precisely 25 minutes before serving. This “tempering” period allows the chocolate molecules to relax, intensifying both flavor and texture. It’s the difference between a good chocolate experience and a transcendent one.
Presentation Worth the Extra Minute
For a truly professional finish, I warm my knife in hot water, wipe it dry, and then make each cut in one clean motion. This gives you those pristine, magazine-worthy slices that showcase the beautiful layers. Just before serving, I dust half the tart with the finest cocoa powder through a small sieve and leave the other half untouched for a dramatic two-tone effect that never fails to impress guests.
These small but significant details are what transform a simple recipe into a signature dessert worth remembering. Trust me—your friends will be requesting “that amazing chocolate hazelnut tart” for years to come.
The Final Slice: Why This Tart Will Become Your Signature Dessert
My journey with this Chocolate Hazelnut Tart began as an experiment but quickly evolved into my most treasured recipe.

I’ve watched friends close their eyes in bliss with the first bite, celebrated milestone birthdays where it took center stage, and even converted self-proclaimed “non-dessert people” into devoted fans.
The beauty of this tart lies in its versatility. Dress it up with gold leaf and edible flowers for a sophisticated dinner party, or serve it simply with a dollop of whipped cream for a cozy family gathering. It transitions effortlessly between seasons—pair it with fresh berries in summer or warm spiced cider in fall.
What I love most about sharing this recipe is knowing it will take on new life in your kitchen. Perhaps you’ll add a hint of orange zest to the crust or experiment with different chocolate varieties. Maybe this tart will become your signature contribution to holiday gatherings or the special dessert you create to mark life’s celebrations.

Ingredients
For the Hazelnut Crust:
- 1½ cups all-purpose flour
- ½ cup hazelnut flour (ground hazelnuts)
- ⅓ cup granulated sugar
- ¼ teaspoon salt
- ¾ cup cold unsalted butter, cubed
- 1 large egg yolk
- 2–3 tablespoons ice-cold water
- 1 teaspoon vanilla extract
For the Chocolate Filling:
- 12 oz high-quality bittersweet chocolate (60-70% cacao), chopped
- 1¼ cups heavy cream
- 2 tablespoons unsalted butter
- 3 tablespoons hazelnut liqueur (like Frangelico) or hazelnut spread
- ¼ teaspoon salt
- 2 large eggs, room temperature
For the Topping:
- ½ cup hazelnuts, toasted and coarsely chopped
- 2 tablespoons chocolate hazelnut spread (like Nutella), warmed slightly
- Flaky sea salt for sprinkling (optional)
- Cocoa powder for dusting (optional)
- Fresh berries for garnish (optional)
Instructions
- Prepare the Hazelnut Crust: In a food processor, pulse together flour, hazelnut flour, sugar, and salt until combined. Add cold butter cubes and pulse until mixture resembles coarse crumbs. Add egg yolk, 2 tablespoons ice water, and vanilla extract. Pulse just until dough begins to come together (add the additional tablespoon of water only if needed). Turn dough onto a lightly floured surface, form into a disc, wrap in plastic, and refrigerate for at least 1 hour.
- Blind Bake the Crust: Preheat oven to 375°F (190°C). Roll out the chilled dough on a lightly floured surface to about ⅛-inch thickness. Transfer to a 9-inch tart pan with a removable bottom, pressing gently into the corners. Trim excess dough. Prick the bottom all over with a fork. Line with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes, then remove weights and parchment. Return to oven and bake for an additional 5-7 minutes until light golden. Reduce oven temperature to 350°F (175°C).
- Make the Chocolate Filling: Place chopped chocolate in a medium heat-proof bowl. In a saucepan, bring heavy cream just to a simmer over medium heat. Pour hot cream over chocolate and let stand for 1 minute, then whisk until smooth. Add butter and whisk until melted and incorporated. Stir in hazelnut liqueur or hazelnut spread and salt. Let cool for 5 minutes. In a small bowl, lightly beat the eggs, then gradually whisk into the chocolate mixture until well combined.
- Bake the Tart: Pour the chocolate filling into the pre-baked crust. Bake at 350°F (175°C) for 20-25 minutes, until the filling is set around the edges but still slightly jiggly in the center (it will continue to set as it cools). Remove from oven and let cool on a wire rack for at least 1 hour.
- Add the Toppings: Once the tart has cooled completely, drizzle the warmed chocolate hazelnut spread over the top in a decorative pattern. Arrange the toasted chopped hazelnuts around the edge or over the entire surface. If desired, sprinkle with a small amount of flaky sea salt and dust lightly with cocoa powder.
- Chill and Serve: Refrigerate the tart for at least 2 hours before serving to allow the filling to fully set. Remove from refrigerator about 20 minutes before serving to take the chill off for the best flavor and texture.
Serving Suggestions:
Serve slices of this decadent tart with a dollop of lightly sweetened whipped cream, a scoop of vanilla or hazelnut gelato, or fresh berries. For an elegant presentation, dust plates with cocoa powder before plating slices, and garnish with a whole toasted hazelnut and a small edible gold leaf. This tart pairs beautifully with coffee, espresso, or a glass of dessert wine.
Notes
Pro Tips:
- Toast hazelnuts for both the crust and topping by spreading them on a baking sheet and baking at 350°F (175°C) for 8-10 minutes until fragrant. Rub them in a clean kitchen towel to remove most of the skins for a smoother flavor.
- Use the highest quality chocolate you can find—it’s the star ingredient and will significantly impact the flavor of your tart.
- For a smoother filling, strain the chocolate mixture through a fine-mesh sieve after adding the eggs to remove any potential lumps.
Common Mistakes to Avoid:
- Overworking the tart dough, which can make it tough rather than tender and flaky.
- Overbaking the filling, which can cause it to become dry or grainy. The center should still have a slight jiggle when you remove it from the oven.
- Using chocolate with too high or too low cacao percentage—aim for 60-70% for the perfect balance of sweetness and complexity.
Storage Instructions:
The tart can be stored covered in the refrigerator for up to 4 days. For the best taste and texture, let slices come to room temperature for about 20 minutes before serving. The tart can also be frozen (without toppings) for up to 1 month—wrap tightly in plastic wrap and aluminum foil, then thaw overnight in the refrigerator and add toppings before serving.
