Italian Chocolate Hazelnut Torte Recipe

Recipe by Pedro M. A. Neves

This Italian Chocolate Hazelnut Torte is a rich, decadent dessert that combines dark chocolate with ground toasted hazelnuts in a dense, fudgy cake. Inspired by the hazelnut traditions of Piedmont, this torte delivers intense chocolate flavor with a subtle nutty depth and a luxuriously moist crumb that improves over a day of aging.

Ingredients

• 200 g dark chocolate (70% cacao)
• 120 g unsalted butter
• 150 g roasted hazelnuts, finely ground
• 4 large eggs, separated
• 100 g granulated sugar
• 30 ml strong espresso, cooled
• 2 ml vanilla extract
• 1 g sea salt
• 5 g all-purpose flour
• 5 g unsweetened cocoa powder (for dusting)

Instructions

1. Preheat your oven to 180°C (350°F). Line a 22 cm (9 inch) round springform pan with parchment paper and lightly butter the sides.

2. Chop the dark chocolate into small pieces and place in a heatproof bowl. Cut butter into chunks and add to the chocolate. Set the bowl over a pot of gently simmering water, stirring occasionally until completely melted and smooth. Remove from heat and let cool slightly.

3. Stir the cooled espresso and vanilla extract into the chocolate mixture. Add the finely ground hazelnuts and flour, stirring until well incorporated.

4. In a separate bowl, whisk the egg yolks with half of the sugar (50 g) until pale and thick, about 2 minutes. Fold the yolk mixture into the chocolate-hazelnut base until no streaks remain.

5. In a clean, dry bowl, whip the egg whites with salt using an electric mixer until soft peaks form. Gradually add the remaining sugar (50 g) while continuing to beat until stiff, glossy peaks form.

6. Gently fold one-third of the egg white mixture into the chocolate mixture to loosen it, then carefully fold in the remaining egg whites in two additions until just combined and no white streaks are visible.

7. Pour the batter into the prepared pan, smoothing the top gently. Bake for 32-35 minutes, until a toothpick inserted in the center comes out with just a few moist crumbs—the torte should still jiggle slightly in the center.

8. Remove from the oven and let cool in the pan for 15 minutes. Run a thin knife around the edges and release the springform, then let the torte cool completely on a wire rack, about 1 hour.

9. Once fully cooled, dust lightly with cocoa powder using a fine sieve. Chill for at least 2 hours or overnight before serving to allow flavors to develop and the crumb to set.

Substitutions

• Replace ground hazelnuts with finely ground almonds or walnuts for a different nutty profile
• Substitute dark chocolate with milk chocolate (55% cacao) for a sweeter, less intense torte
• Use 60 ml of strong brewed coffee instead of espresso for a milder coffee flavor
• Replace butter with coconut oil (use 100 g) for a dairy-free version, though the flavor will shift slightly

Tips

• Do not overbake—the torte continues to cook as it cools, so a slightly underdone center ensures a fudgy texture rather than a dry cake
• Make this torte 1-2 days ahead; aging allows the hazelnuts and chocolate to meld and intensify, improving both flavor and texture
• Use room-temperature eggs for better incorporation and lighter, more stable meringue formation
• Ensure your egg white bowl is completely grease-free; even traces of yolk will prevent proper whipping

Hazelnut tortes hold special significance in Italian cuisine, particularly in Piedmont (Piemonte), where hazelnuts have been cultivated for centuries and feature prominently in desserts and confections. This style of flourless or mostly flour-free chocolate and nut cake reflects both Italian patisserie traditions and the ancient practice of using ground nuts as a binder in place of large quantities of flour.
