In a bowl, combine the milk and sugar.
In a large bowl, combine the flour, yeast, and salt. With a wooden spoon or with your hands, stir in the milk mixture, egg and butter to the dry ingredients, stirring vigorously until the dough begins to form.
Place the dough on a floured work surface and knead for about 5 minutes or until the dough is smooth. Form a ball and place in a lightly oiled bowl. Cover the bowl with a damp cloth and let rest in a warm and humid place for 10 minutes.
Line a 43 X 30-cm (17 X 12-inch) baking sheet with parchment paper.
Place the dough on a lightly floured work surface and add the chocolate chips while kneading the dough. Divide the dough into 8 equal pieces. Shape balls by rolling them with your hands on the counter and place on the baking sheet. Let rise for about 45 to 60 minutes in a warm and humid place, or until the balls double in size.
With the rack in the middle position, preheat the oven to 180 °C (350 °F).
With a brush, lightly coat the loaves with the beaten egg. Bake for 25 to 30 minutes. Let cool and enjoy!
