Cut butter into cubes. Mix flour, salt, icing sugar, butter and 1 egg with the dough hooks of the hand mixer to a smooth dough. Wrap in foil and chill for about 15 minutes
Pour the apricots into a sieve and drain well. Mix 1 egg, sugar, vanillin sugar and quark until smooth
Roll out the dough on the floured work surface. Cut out 18 flowers (approx. 10 cm Ø), but knead and roll out the dough again and again. Line every second trough of a greased muffin tray (24 troughs) with 1 dough flower. Prick the dough base several times with a wooden skewer and bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 13 minutes
Remove the muffin tray, fill flowers with the cheese mixture to the brim and place 1 half apricot on each. Bake again at the same temperature for about 10 minutes. Take out, let cool and take out of the tin. Grease the hollows of the muffin tray again and process the remaining ingredients in the same way. Dust with icing sugar before serving
waiting time approx. 2 hours
