Whip the cream until stiff and beat the snow out of the egg white.
Beat the butter until frothy, then stir in the sugar and egg yolks. Mix the baking powder with the flour and stir into the dough a spoonful at a time. Now fold in the stiff egg whites and then fold in the stiffly whipped cream and grated chocolate. Pour the batter into a greased ring cake pan.
Bake in a preheated oven at 190 ° C for about 60 minutes.
Tastes fantastic, but unfortunately it`s a calorie bomb.
