Knead 100 g butter in pieces, 250 g flour, 75 g sugar, 1 packet vanilla sugar, cocoa, 1 egg and 1 pinch of salt with the dough hooks of the hand mixer. Quickly work into a smooth dough with your hands. Wrap in cling film and chill for about 30 minutes. Put 50 g of dough aside. Roll out the rest of the dough into a circle (approx. 34 cm Ø) on a floured work surface. Line a springform pan (26 cm Ø) with it.
Pull the dough up about 4 cm along the edge. Prick the base several times with a fork. Put it in a cold place. Wash, halve and stone the apricots.

Stir the egg yolks one after the other into the fat-sugar mixture. Stir in quark, pudding powder and espresso. Beat egg whites and 1 pinch of salt until stiff and fold in. Stir in the apricots.
