Warm the milk in a small pot lukewarm. Dissolve yeast in it. Put flour, 125 g sugar, salt, 1 egg and fat into a mixing bowl, pour milk over it and knead with the dough hooks of the hand mixer.
Cover the dough and let it rise in a warm place for about 40 minutes. In the meantime, drain the cherries and peaches separately on a sieve. Mix the sour cream, vanillin sugar, remaining sugar and remaining eggs.
Knead the dough again well, roll out on the well greased fat pan (32 x 39 cm) of the oven and let it rise again covered in a warm place for about 15 minutes. Press the peaches and cherries into the dough, press a few more depressions into the dough by hand, pour over the top and bake in the preheated oven (electric range: 200 °C/ gas: level 3) for approx. 30 minutes.
Take the cake out of the oven and sprinkle with sugar crystals. Whipped cream tastes good with it.
