For the blackberry and pear cake, prepare a yeast dough from the dough ingredients:
Put the flour in a bowl and make a well in the center. Crumble in the yeast and sprinkle with sugar.
Pour the lukewarm milk over it and stir a little flour from the edge into the liquid in the center.
Cover with a tea towel and let stand for a quarter of an hour.
Then knead in the eggs, sugar, soft butter and a pinch of salt with the dough hook.
If necessary, knead in some more flour or milk. It should be a smooth dough that comes away from the side of the bowl.
Cover the dough again with a tea towel and let rise in the warm for about 1 hour. It should double in volume.
For the topping, sort and clean the blackberries.
Peel the pears, remove the core and slice the fruit.
Spread the dough on a baking tray lined with baking paper.
Spread the fruit decoratively on it and let the cake rise again for half an hour.
Heat the oven to 180 °C.
Bake the blackberry and pear cake on the middle shelf for about 40 minutes.
Heat the quince jelly with 2 tablespoons of water.
Remove the blackberry and pear cake from the oven and spread with the hot quince jelly.
Serve sprinkled with powdered sugar.
