Quickly mix flour, baking powder, butter in flakes, 90 g sugar and 1 egg with the dough hooks of the hand mixer to a smooth dough. Wrap dough in foil and chill for approx. 30 minutes. Grease a springform pan (26 cm Ø) and dust with flour. Halve the dough. Roll out the first half of the dough on a well floured work surface and line the springform pan with the dough, pressing down the edge.
Roll out the second half of the dough to a rectangle (30 x 15 cm) on a well floured work surface and spread evenly with strawberry jam. Roll up from the long side and cut into 12 slices. Beat 150 g sugar and 2 eggs with the whisk of the hand mixer until foamy. Add quark, pudding powder and orange juice and stir in. Pour the quark cream onto the base and smooth it down. Spread short pastry slices on top and bake in the preheated oven (electric cooker: 175 °C/ convection oven: not suitable/ gas: level 2) for approx. 60 minutes. If necessary, cover with baking paper after 40 minutes of baking time. Remove the cake from the oven and let it cool down for 10 minutes. Loosen the edge of the springform pan and allow the cake to cool completely.
