I recommend putting the countertop before greasing it with cream on a grill (I used the one in the microwave).
Under the grill I spread some baking paper, so I can easily pour the icing, which you can recycle afterwards.
Prepare the icing: Put 2 tablespoons of water in a small saucepan, when it starts to boil, add the sugar and mix with a spoon until it melts. Then pour 2 tablespoons of liqueur or brandy and broken chocolate pieces - stir until the chocolate melts. Add the butter, let it melt - mix well to blend the composition and remove from the heat. Allow to cool to room temperature.
Prepare the double amount of icing, to spread it lightly over the surface of the cake, without leaving ugly marks on the cake. Pour the icing and carefully spread it with a knife.
