Ingredients
- 200g all-purpose flour (1⅔ cups)
- 50g unsweetened cocoa powder (½ cup)
- 7g baking powder (1½ teaspoons)
- 4g fine sea salt (¾ teaspoon)
- 150g whole eggs at room temperature (about 3 large)
- 120g granulated sugar (⅔ cup)
- 90ml whole milk (⅜ cup)
- 45ml neutral oil (3 tablespoons)
- 10ml vanilla extract (2 teaspoons)
- 250g unsalted butter, softened (1¾ sticks)
- 180g roasted hazelnut paste (¾ cup, such as Nocciola d'Alba)
- 100g dark chocolate (72% cacao), melted and cooled (3.5 oz)
- 60g powdered sugar (½ cup)
- 10g unsweetened cocoa powder for dusting (2 teaspoons)
- 30g whole roasted hazelnuts for garnish (¼ cup)
Instructions
-
Preheat oven to 175°C (350°F). Grease and line two 20cm (8-inch) round cake pans with parchment paper.
-
Sift together flour, cocoa powder, baking powder, and salt in a medium bowl; set aside.
-
Whisk eggs and granulated sugar in a large bowl for 4-5 minutes until pale, thick, and ribbony.
-
Gently fold the flour mixture into the egg mixture in two additions, alternating with the milk and oil mixture (combine milk, oil, and vanilla first). Fold until just combined and no streaks remain.
-
Divide batter evenly between the two prepared pans and smooth the tops with a spatula.
-
Bake for 32-35 minutes until a skewer inserted in the center comes out with just a few moist crumbs. Cool in pans for 10 minutes, then turn out onto wire racks to cool completely.
-
Beat softened butter in a mixing bowl until pale and creamy, about 3 minutes. Add hazelnut paste and beat until fully incorporated and smooth.
-
Gently fold the cooled melted chocolate into the hazelnut cream until fully blended. Sift in powdered sugar and fold until the frosting is silky and spreadable.
-
Place one cake layer on a serving plate. Spread a generous layer of gianduia cream over the top using an offset spatula. Top with the second cake layer.
-
Frost the top and sides of the assembled cake with the remaining gianduia cream, creating smooth sides and a level top. Dust lightly with cocoa powder and scatter whole roasted hazelnuts around the top edge.
Substitutions
- For nut-free: replace hazelnut paste with equal weight of creamy roasted almond butter, omit whole hazelnut garnish
- For gluten-free: substitute all-purpose flour with certified gluten-free 1:1 baking flour in same weight
- For dairy-free: use vegan butter (such as European-style with 82% fat) and replace milk with unsweetened oat milk
- For refined sugar-free: use erythritol or monk fruit sweetener, 1:1 by weight, in both cake and frosting
Tips
- Use high-quality Italian hazelnut paste (Nocciola d'Alba PDO) for authentic flavor; avoid hazelnut spread, which contains added sugar
- Ensure all ingredients, especially eggs, are at room temperature for maximum volume and lift in the cake
- Do not over-fold the batter once dry ingredients are added; stop as soon as no flour streaks remain to keep the cake tender
- Chill the frosted cake for 1-2 hours before serving; this makes slicing cleaner and allows flavors to set
Gianduia is the signature chocolate-hazelnut blend of Piedmont, born in 18th-century Turin when Napoleon's trade blockade made cacao scarce and local hazelnuts became the stretching ingredient. Torta Gianduia became a celebrated way to showcase this regional treasure, and remains a proud emblem of Piedmontese pastry craftsmanship.
