Cream butter, icing sugar and vanilla sugar with the whisk of the hand mixer. Stir in almonds and coffee. Spread the cream on the lady fingers. Cover with the remaining lady fingers and sprinkle with the rest of the whiskey. Chill the cake for about 2 hours.
Whip the cream until stiff, while pouring in the cream firming agent and sugar. Remove the cake from the springform pan and place on a cake platter. Spread the cream all around the cake. Put it in a cold place. Chop the chocolate coating and melt in a warm water bath. Pour into a freezer bag and cut off a small corner. Decorate the cake with chocolate coating, sponge cakes and fruit
