Coarsely chop the chocolate coating and melt it in a warm water bath. Drain the cherries, collect the juice and measure 50 ml. Put some cherries aside for decoration. Beat the fat, sugar and 1 packet of vanilla sugar with the whisk of the hand mixer until thick and creamy.
Add couverture and stir in. Stir in the eggs one by one. Mix 450 g flour, baking powder and cocoa. Alternately stir kirsch and 50 ml cherry juice into the egg mixture. Dust the cherries with 1 tablespoon of flour and carefully fold into the dough.
Grease the pancake tin (2.5 litres capacity) and dust with flour. Pour in the dough and bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150/ gas: level 2) for 50-60 minutes. Take the cake out of the oven and let it cool down for 10 minutes.
Turn the cake out of the tin onto a cake rack and let it cool down completely. Whip the cream until stiff, while pouring in 1 sachet of vanilla sugar. Fill approx. 2 tablespoons of cream into a piping bag with star-shaped spout.
Spread the cloudy cake all around with the remaining whipped cream. Spray tuffs on the cake and decorate with remaining cherries. Sprinkle with chocolate shavings.
