Warm the milk slightly and stir in 1 tablespoon of sugar. Crumble in the fresh yeast, then let it stand for 5-10 minutes until foamy.
In a large bowl, combine the flour, salt, and the remaining sugar. Add the foamy yeast mixture, melted butter, and eggs. Knead until a smooth dough forms.
Place the dough on a lightly floured surface and knead for another 5-10 minutes. Then, place it in a lightly oiled bowl, cover with a kitchen towel, and let it rise for about 1 hour, or until doubled in size.
Melt the dark chocolate and mix with the cocoa powder. Let it cool slightly.
Roll out the risen dough into a rectangle. Spread the melted chocolate mixture evenly over the dough, then tightly roll it up like a log.
Cut the roll lengthwise in half, then twist the two strands together, exposing the chocolate layers.
