Ingredients
- 200g dark chocolate

 - 4 large eggs, separated
 - 150g caster sugar
 - 300ml heavy cream
 - 2 tbsp hazelnut liqueur
 
Instructions
- Step 1: Melt the dark chocolate in a heatproof bowl over simmering water, stirring until smooth.

 - Step 3: Gently fold the melted chocolate and ground hazelnuts into the egg yolk mixture until well combined.
 - Step 4: In a clean bowl, beat the egg whites until stiff peaks form, then carefully fold them into the chocolate mixture to keep it light and airy.
 - Step 5: Pour the batter into a greased cake pan and bake in a preheated oven at 180°C for 25-30 minutes, or until set but still slightly wobbly in the center.
 - Step 6: Allow the cake to cool completely in the pan before topping.
 - Step 7: Whip the heavy cream with the hazelnut liqueur until soft peaks form, then spread it evenly over the cooled cake.
 - Step 8: Chill the cake in the refrigerator for at least one hour before serving to let the flavors meld.
 
Tips & Variations
- For a nut-free version, substitute hazelnut liqueur with vanilla extract and omit the hazelnuts.
 - To toast hazelnuts, spread them on a baking sheet and bake at 180°C for 10 minutes, then rub off the skins for a smoother texture.
 - If hazelnut liqueur is unavailable, almond or coffee liqueur can add interesting complementary flavors.
 - Use a water bath during baking for an even, gentle heat if you want a creamier mousse texture.
 
Storage
Store the cake covered in the refrigerator for up to 3 days. Reheat is not recommended due to the mousse texture, but bringing it to room temperature before serving will enhance the flavor and softness.

FAQs
Can I make this cake ahead of time?
Yes, this cake can be made a day in advance. Prepare it fully, then keep it chilled until ready to serve for best texture and flavor.
Can I use regular sugar instead of caster sugar?
Yes, but for a smoother texture and easier dissolving in the egg yolks, caster sugar is preferred. If using regular sugar, pulse it in a blender to make it finer.

Ingredients
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
- 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.
 - 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.
 - Combine Chocolate and Hazelnuts: Gently fold the melted chocolate and ground toasted hazelnuts into the egg yolk and sugar mixture until well combined.
 - 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.
 - Fold Egg Whites: Carefully fold the beaten egg whites into the chocolate mixture in three batches to maintain the airy texture of the batter.
 - 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.
 - 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.
 - 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.
