Warm the milk lukewarm. Dissolve yeast in the milk. Put flour, 50 g sugar, egg, salt, cardamom and 75 g soft butter in a bowl. Add yeast milk and knead with the dough hooks of the hand mixer to a smooth dough. Cover the dough and let it rise in a warm place for about 30 minutes (until the dough has doubled).
Briefly knead the dough with your hands on a floured work surface, then roll out rectangularly (approx. 20 x 50 cm). Melt 50 g butter. Remove 1 tablespoon of butter. Brush the dough with the remaining butter. Mix 50 g sugar and cinnamon. Take off 1 tablespoon, sprinkle the remaining sugar-cinnamon evenly on the dough. Roll up the dough from the long side and cut into 16 slices. Put snails on 3 baking trays lined with baking paper, press the ends of the dough firmly and flatten them again. Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 10-12 minutes until light brown.
