Soak gelatine in cold water. Cream quark, 50 g sugar and 1 packet of vanilla sugar with the whisk of the hand mixer. Whip 200 g cream until stiff. Squeeze the gelatine and dissolve.
Mix with 3 tablespoons of quark and then stir back into the mixture. Fold in cream and chocolate rasp and chill. Separate the eggs. Cream the fat, 1 packet of vanilla sugar and 1 pinch of salt with the whisks of the hand mixer.
Stir in the egg yolks one after the other. Alternately stir in flour and 200 g cream. Beat the egg whites until stiff, then add 100 g sugar. Fold the beaten egg whites into the dough. Grease and preheat a square waffle iron.
Bake about 7 double wafers one after the other from the dough. Let the waffles cool down on a cake rack. Fill the cream in a piping bag. Halve the waffles, squirt the cream on one half and place the other half on top.
