Put flour, 200 g sugar, vanillin sugar, butter in flakes, cream cheese and 2 eggs in a large mixing bowl. Knead with the dough hook of the hand mixer. Then knead quickly with your hands to a smooth dough. Cover and chill for about 1 hour. In the meantime peel, quarter, core and cut apples into pieces. Mix with juice from 1 lemon.
Bring 350 ml apple juice, quince jelly, 100 g sugar and rum flavouring to the boil. Add apple pieces and simmer covered for about 5 minutes. Mix pudding powder with 100 ml apple juice and stir into the apple compote. Simmer for 1 minute, remove from heat. Grease the fat pan of the oven (32 x 39 cm) and dust with flour. Roll out half of the dough on a floured work surface to the size of the fat pan, line the bottom with it. Sprinkle breadcrumbs on top. Spread the apple compote on the base, leaving a 1 cm wide edge on each side. Roll out the rest of the dough to the same size, lay carefully on the apples. Press the edges of the dough well together. Carefully prick the top of the dough several times with a fork. Whisk 1 egg and brush the dough with it.
