Put the milk in a bowl, crumble in the yeast, add the sugar and let rise in a warm place for 10-12 minutes. Add the yeast milk with the oil and salt to the sifted flour and process into a smooth dough.
Knead the dough vigorously and cover it in a warm place and let it rise to double the amount. Grease a baking sheet, roll out the yeast dough, put it in the pan and let rise for another 25 minutes.
In the meantime, use 1 liter of milk, 2 packs of vanilla pudding and sugar to cook a pudding according to the instructions on the package. Stir 500 g of quark into the pudding and pour everything onto the yeast dough.
Preheat the oven and bake at 200 ° C top / bottom heat for about 30 minutes.
Take the cake out of the oven and spread 3 cups of sour cream on the hot cake (mix with sugar beforehand to taste). Finished.
This amount gives me the dough for 1 tray and a round shape (26 cm).
