Mix yeast, sugar and warm milk and let it rise. Mix the eggs with sugar, add flour,, the yeast mixture, warm milk and
work the dough until everything comes together. Slowly add the melted butter, knead it again and leave to rise in a warm place.
Divide the dough into two parts. Roll it out into the shape of a rectangle, fill with filling evenly and roll them up. Place them in greased molds and let them rise. When the dough doubles its volume, put it in the pre-heated oven and bake for 45 minutes. Take the still warm strudels out of the molds and sprinkle with sugar.
