Italian Hazelnut Chocolate Cake Recipe

Recipe by Pedro M. A. Neves

This Italian hazelnut chocolate cake combines ground hazelnuts with dark chocolate to create a rich, moist torte with a delicate crumb. A signature dessert in Piedmont, this cake balances the earthy nuttiness of hazelnuts against the depth of quality chocolate. Perfect for special occasions or as an elegant finishing touch to any Italian meal.

Ingredients

• 200g blanched hazelnuts, finely ground
• 200g dark chocolate (70% cocoa), chopped
• 150g unsalted butter, softened
• 150g granulated sugar
• 4 large eggs, separated
• 50ml whole milk
• 30g all-purpose flour
• 1 teaspoon vanilla extract
• 1/4 teaspoon salt
• Pinch of cream of tartar
• Powdered sugar for dusting (optional)

Instructions

1. Preheat oven to 180°C (350°F). Butter and line a 23cm (9-inch) round cake pan with parchment paper.

2. Melt the chopped chocolate in a heatproof bowl set over simmering water, stirring frequently until smooth. Remove from heat and let cool for 2 minutes.

3. In a large bowl, cream together the softened butter and granulated sugar until pale and fluffy, about 3 minutes, using an electric mixer.

4. Add egg yolks one at a time to the butter mixture, beating well after each addition. Stir in the cooled chocolate, vanilla extract, and milk until fully combined.

5. Fold the ground hazelnuts and flour together gently into the chocolate batter using a spatula until just combined.

6. In a clean, dry bowl, whisk the egg whites with cream of tartar and salt until stiff peaks form. Gently fold the egg whites into the chocolate-hazelnut mixture in two additions, preserving the airiness.

7. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 35-40 minutes until a toothpick inserted near the center comes out with just a few moist crumbs.

8. Allow the cake to cool in the pan for 10 minutes, then invert onto a wire cooling rack. Cool completely to room temperature, approximately 2 hours.

9. Once cool, dust lightly with powdered sugar if desired. Slice with a sharp knife wiped clean between cuts for neat portions.

Substitutions

• Use 200g of almond flour plus 30g chopped roasted hazelnuts for a milder nut flavor
• Substitute milk with hazelnut liqueur (Frangelico) reduced to 25ml for an intensified hazelnut profile
• Replace butter with the same weight of softened cream cheese for a tangier, denser crumb
• Use 60% cocoa chocolate for a sweeter, less bitter cake

Tips

• Toast the hazelnuts lightly before grinding to enhance their flavor; cool completely before adding to the batter to prevent seizing the chocolate
• Room-temperature eggs incorporate more smoothly and create a lighter, more stable batter
• Do not skip the cooling period in the pan; it allows the structure to set properly and prevents cracking when inverted
• This cake stores well wrapped in plastic wrap for up to three days, and flavors deepen slightly after 24 hours

The Italian hazelnut chocolate cake is deeply rooted in Piedmont's culinary tradition, where hazelnuts from the Langhe region are celebrated as a prized ingredient. This cake represents the Italian philosophy of combining simple, quality ingredients to create refined simplicity rather than excessive decoration.
