Additonal Notes
Feeld free to add additional stuff to the cake e.g. chocolate pieces or nuts.
If you like you could spread 100 g of any chocolate you like on top of the cakes surface 5min before you should get it out of the oven.
Distribute it evenly when it is stil warm and fluid. After the cake cooled down, put it in the freezer to make the chocolate solid again.
