Preheat the oven to 175°C (350°F). Grease an 20 cm (8-inch) round cake pan and line its base with parchment paper.
Finely grind the roasted hazelnuts in a food processor. Pulse briefly to prevent them from turning into hazelnut butter.
Place the dark chocolate and unsalted butter in a heatproof bowl. Melt them together over a pan of gently simmering water or in short microwave intervals, stirring until smooth. Set aside to cool slightly.
In a large mixing bowl, beat the eggs and granulated sugar for 2–3 minutes, until pale and slightly thickened. Mix in the vanilla extract.
Slowly add the melted chocolate and butter mixture to the eggs, whisking continuously until evenly combined. Stir in the whole milk.
In a separate bowl, combine the all-purpose flour, ground hazelnuts, cocoa powder, baking powder, and salt.
Add the dry mixture to the wet mixture in two additions. Fold gently after each addition just until no dry streaks remain; do not overmix.
Transfer the batter to the prepared pan and smooth the surface.
Bake for 30–35 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs but no raw batter.
Let the cake cool in the pan for 10 minutes. Turn it out onto a wire rack, remove the parchment paper, and allow it to cool completely before slicing and serving.
