In a large bowl, combine the flour, yeast, sugar, and salt. Add the warm milk and softened butter in pieces. Knead until the dough pulls away from the sides of the bowl. Shape the dough into a ball, cover the bowl with plastic wrap, and let it rise in a warm place for about 2 hours, until doubled in size.

Once the dough has risen, punch it down on a floured work surface, knead it again, and divide it into 2 equal balls. Roll each ball into a rectangle about 1/2 inch (1 cm) thick. Cut each large rectangle into 5 smaller rectangles.

Cut the chocolate into bars. (I cut a row of chocolate in half lengthwise.) Place a chocolate bar on a small rectangle of dough and roll it up. Place a second chocolate bar on the dough and roll again. Seal the edges of the dough with a little water.

Place the chocolate rolls on a baking sheet lined with parchment paper. Cover with a kitchen towel and let rise again for about 30 minutes. Preheat the oven to 350°F (180°C). Brush the tops of the rolls with milk and bake for about 15 to 20 minutes.
