Ingredients

Scale

Cake

  • 200g dark chocolate
  • 100g hazelnuts, toasted and ground
  • 4 large eggs, separated
  • 150g caster sugar

Topping

  • 300ml heavy cream
  • 2 tbsp hazelnut liqueur

Instructions

  1. Melt Chocolate: Place the dark chocolate in a heatproof bowl set over simmering water and stir until completely melted and smooth. Remove from heat and let cool slightly.
  2. Prepare Egg Yolk Mixture: In a separate bowl, whisk the egg yolks with the caster sugar until the mixture is thick, pale, and creamy. This step incorporates air and adds volume to the batter.
  3. Combine Chocolate and Hazelnuts: Gently fold the melted chocolate and ground toasted hazelnuts into the egg yolk and sugar mixture until well combined.
  4. Beat Egg Whites: In another clean bowl, whisk the egg whites until stiff peaks form, ensuring the whites are stable and can add lightness to the cake.
  5. Fold Egg Whites: Carefully fold the beaten egg whites into the chocolate mixture in three batches to maintain the airy texture of the batter.
  6. Bake the Cake: Pour the batter into a greased cake pan, smoothing the top with a spatula. Bake in a preheated oven at 180°C (350°F) for 25-30 minutes, or until a skewer inserted into the center comes out with moist crumbs.
  7. Prepare Whipped Cream Topping: Whip the heavy cream with the hazelnut liqueur until soft peaks form. This will create a light and flavorful topping for the cake.
  8. Assemble: Let the cake cool completely in the pan before spreading the hazelnut whipped cream evenly over the top. Chill if desired before serving.

Notes

  • Ensure egg whites are at room temperature for better volume when whisking.
  • Do not overbake the cake to keep it moist and mousse-like.
  • Toasting hazelnuts enhances their flavor; toast in a dry pan until fragrant and slightly browned.
  • The hazelnut liqueur can be substituted with vanilla extract for a milder flavor.
  • Use a rubber spatula to fold mixtures gently to preserve the airiness.
