In a small pot over low heat, heat the milk and cream until warm. Be careful not to overheat it or it will kill the yeast. Add yeast and mix to combine.
In a large mixing bowl whisk together the melted butter and sugar, then beat in the egg and the milk-yeast mixture until smooth. Add the flour in a couple additions. Knead the dough until it’s completely smooth and soft and all the flour is absorbed.
Cover the bowl with a kitchen towel and let the dough rise, in a warm spot, for one to two hours or until doubled in size.
Sprinkle chocolate chips over the dough and knead the chocolate chips into the dough until they are evenly distributed.
Divide the dough into 8 equal pieces. Shape the pieces of dough into small oblong loaves with tapered ends.
Arrange the loaves on a parchment paper lined baking sheet, cover with a towel and let them rise at room temperature for another 30 minutes.
Preheat the oven to 475°F with the rack in the middle of the oven.
Uncover the loaves, brush the tops and sides with the egg wash, then use a sharp knife to cut a few diagonal slashes across the top. Bake for 10 to 12 minutes or until dark golden brown.
Serve warm or at room temperature after resting on a cooling rack.
