For the cream, roughly chop 450 g of chocolate coating. Heat the cream in a saucepan and remove from the heat. Melt the chocolate in the hot cream while stirring. Spread the mixture evenly in two clean dry mixing bowls, let it cool down a little. Cover the surface with foil and leave to cool for 3-4 hours until the mixture has cooled down completely. For the base, roughly chop 100 g chocolate coating and melt over a warm water bath. Leave to cool at lukewarm temperatures. Cream the fat, 50 g icing sugar and chocolate coating with the whisk of the hand mixer.
Separate the eggs. Stir in all egg yolks one after the other. Beat the egg whites until stiff, adding salt and 25 g icing sugar. Pour onto the chocolate mixture and fold in briefly. Mix flour and cocoa, sieve over it and fold in. Line the bottom of a springform pan (24 cm Ø) with baking paper. Pour in the dough and smooth it down. Bake in the preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: level 2) for 25-35 minutes. Loosen the edge with a knife and let it cool down on a cake rack in the form. Chop 100 g chocolate coating, melt over a warm water bath. Place on a marble board, spread thinly and chill. When the couverture has just solidified, use a spatula to remove the rolls. Place in a cold place. Remove the base from the mould, peel off the baking paper and place a cake ring around the base. Sprinkle the base with coffee.

Use the whisk of the hand mixer to whip a portion of chocolate cream until creamy (approx. 30 seconds). Spread the cream on the cake base and smooth it down. Coarsely chop the meringue with a knife and spread on the chocolate cream. Whip the second portion of the chocolate cream until creamy, spread on the meringue and spread it wavy. Chill for approx. 2 hours. Remove from the ring just before serving. Decorate with chocolate rolls and dust with cocoa
