Grease the recesses of a mini muffin tray (24 recesses). Knead 250 g flour, salt, icing sugar, 125 g butter in pieces and 1 egg first with the dough hooks of the mixer, then briefly with your hands to a smooth dough.
Wrap in foil and chill for about 15 minutes. Drain the apricots well. Mix quark with 1 egg, sugar and vanilla sugar.
Roll out the dough on a floured work surface until it is about 3 mm thin. Cut out 18 flowers (approx. 10 cm Ø) with a cookie cutter. Put 9 flowers on the muffin tray. Prick the pastry bases several times with a wooden skewer.
Pre-bake in the preheated oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer) for 12-13 minutes.
Remove the sheet metal. Fill the flowers up to the edge with curd cream, place 1 apricot on top of each flower with the convex side up. Bake again for about 10 minutes. Take out, let cool down and remove from the tin.
Grease the muffin tray again and bake another 9 cakes in the same way. Let them cool down and dust with icing sugar.
