Melt the dark chocolate over a low heat with the sweet cream and coffee.
Mix the cream cheese with the sugar and vanilla sugar.
Beat the eggs lightly with a pinch of salt.
Add the eggs to the cream cheese and mix well until smooth.
Slowly dribble in the grated and melted chocolate. Mix well.
Preheat the oven to 180 degrees.
Prepare a cake pan with removable sides.
Roll out the cake dough into a round shape larger than the diameter of the pan.
Place the dough in the pan, covering the bottom and all the way up the sides.
Pour the cream cheese and chocolate into the pan. Level.
Brush the dough with beaten egg.
Place the pan in the heated oven.
Bake for 40-45 minutes, until it is brown around the edges.
Remove from the oven and leave on a cooling tray.
Divide up the cake as soon as it has cooled completely.
Serve it with a good appetite and good mood!
