For the nut buns, mix flour, dry yeast, sugar, vanilla sugar, salt, lemon sugar and knead with yolks and warm milk a yeast dough with dough hook until it comes off the bowl.
Then let the dough rise until it doubles in size. Roll out dough and spread with the following filling: Heat milk, stir in nuts, powdered sugar, vanilla sugar, raisins and rum.
Let the filling cool down and spread it on the rolled out yeast dough, sprinkle it with cinnamon and roll it up. Cut slices of 2 cm thickness and flatten slightly and place on a baking tray lined with baking paper and bake at 180°C degrees for about 25 minutes.
Mix the powdered sugar with the rum to make a thick mixture and brush the glaze over the nut buns while they are still hot.
