Put the flour in a bowl, add sugar and butter to the edge. Make a well in the middle and crumble the yeast into it, mix with lukewarm milk and a little sugar to form a pre-dough and leave to rise covered.
Chop the chocolate into large pieces and add to the pre-dough. Knead everything into a yeast dough and let rise.
Divide the dough into 10 equal pieces and shape into rolls. Place on a baking sheet lined with baking paper and let rise again.
