In the meantime, knead 150 g sugar, 1 packet of vanilla sugar, 1 pinch of salt, 300 g flour, 1 egg and 175 g cold butter first with the dough hooks of the hand mixer, then with your hands to form crumbles. Cut the crumbles in half. Knead cinnamon under one half and cocoa under the other half, chill. Knead the dough well with floured hands on a floured work surface. Put into a greased fat pan of the oven (32 x 39 cm) and spread evenly with floured hands. Let it rise again in a warm place for about 30 minutes. Press the dough in several times with your fist. Spread the jam in blobs on the dough. Spread 75 g soft butter in flakes on top. Spread crumbles alternately in a zebra pattern.
