Knead flour, baking powder, fat, sugar and egg to a smooth shortcrust pastry, cover and put in a cool place for about 30 minutes. Grease a springform pan (26 cm Ø). Roll out 2/3 of the dough on the bottom of the mould. Prick several times with a fork. Close the edge of the mould around it. Form the rest of the dough into a roll, place it on the edge of the mould and press it up 3-4 cm high.
Lay parchment paper on the dough. Fill with dried peas up to the height of the dough crust. Bake in the preheated oven (electric oven: 200 °C/ gas: level 3) on the lower level for 20-25 minutes. Peel, quarter, core and cut apples into fine pieces. Sprinkle with lemon juice. Sprinkle sugar, vanillin sugar and cinnamon over the apples and mix carefully. Heat the fat in a large pot. Steam apples in it at low heat for 5-8 minutes. Drain. Remove parchment paper and peas from the cake base. Spread steamed apple pieces on top. Knead the marzipan, icing sugar and egg to a spreadable mixture and fill into a piping bag with star-shaped spout.

Knead the marzipan, icing sugar and egg to a spreadable mixture and fill into a piping bag with star-shaped spout. First spray a grid, then a rim onto the apple tart. Bake the apple tart for another 20-25 minutes on the middle shelf at the same temperature. Carefully loosen the edge of the tin with a knife and let the apple tart cool down well on a cake rack. Heat up the jam and spread it on the cake. Serve dusted with icing sugar. Makes approx. 16 pieces
