Ingredients:

• 12 Tbsp all-purpose flour
• 4 Tbsp cocoa powder
• 16 Tbsp sugar
• 5 Tbsp ground hazelnuts

You need a 10-inch round pan greased with butter and floured.

For chocolate mousse filling:

• 200 g (1 1/5 cups or 7.5 oz) chocolate chips or grated chocolate (semi-sweet, milk or white chocolate)
• 3 egg yolks
• 2 egg whites
• 200 ml (4/5 cup) whipping cream, at room temperature
• 110 g (1/2 cup) sugar, divided
• 3 Tbsp hazelnut liqueur
• 60 g (1/4 cup or 3 oz) unsalted butter
• 14 g unflavoured gelatin

For syrup to moisten cake:

• 200 ml boiled water
• 5 Tbsp sugar
• 1.5 Tbsp rum extract

Boil the water and sugar, add the rum extract and let it cool off.

For chocolate ganache topping:

• 300 ml (1 1/5 cup) whipping cream
• 350 g (2 cups or 13 oz) chocolate chips or grated chocolate (semi-sweet, milk or white chocolate)

Directions:

After you’ve baked the chocolate hazelnut cake let it cool off and cut it horizontally in two.

Line a 10-inch springform pan with foil and place the first layer of your cake.  Moist it with sugar syrup.

Using a spatula, evenly cover the top of the first layer with the chocolate mousse filling.

Place the second layer on top and moist it with sugar syrup. Refrigerate the cake for a few hours.

For the chocolate topping, heat the whipping cream over medium heat, remove from heat, add the chocolate and stir until completely mixed and glossy.

Set aside until it cools off but still has a pouring consistency.

Spread the chocolate ganache over the top and sides of the cake.
