Put the flour in a bowl, pour half of the warm milk into a well and dissolve the crumbled yeast in it. Spread the soft butter around it in flakes, add the remaining milk, sugar, vanilla sugar, salt, cinnamon, raisins and mango cubes. Make a kneading dough from all the ingredients. Shape the dough into a roll (approx. 6 cm diameter), cut the roll into approx. 2 cm thick pieces. Shape it into round or oval rolls according to your taste and place on a baking sheet lined with baking paper. Cover the dough and let it rise in a warm place for about 80-90 minutes, until the dough has risen by half.
