Cream fat, sugar, salt and vanilla sugar. Stir in the eggs one after the other. Cut marzipan into small pieces and stir in. Mix flour and baking powder and stir into the mixture alternately with the milk.
Spread the dough on the greased baking tray (glass tray 32x28 cm). Wash, peel, halve and core the pears. Cut the pear halves in half at the top side close together about 1 cm deep.
Sprinkle the pears with lemon juice and let them soak in briefly. Place the pears on the dough with the top side facing upwards. Press in gently. Bake the cake in a preheated oven (electric: 200 °C/ gas: level 3) for about 30 minutes.
In the meantime, cut the pistachios in half lengthwise. 10 minutes before the end of the baking time, press the pistachios into the dough. One half at the stem end of the pear, two halves at the flower end. Heat the jam and spread it on the cake 5 minutes before the end of the cooking time.
Take out the cake and let it cool down. Serve sprinkled with icing sugar. Whipped cream tastes good with it. Makes about 20 pieces.
