Heat oven to 375 degrees with rack in the middle position
Combine all ingredients except the butter in a mixer fitted with the dough hook and mix on first speed for 5 minutes
Increase to 2nd speed and mix for an additional 10 minutes
Half way through the 2nd speed mixing, add butter cubes
Remove from mixer, round up tightly and let the dough rest (ferment) covered with plastic wrap for one hour
Divide the dough into 65 g units
Shape the units into rounds by rolling them between the palm of your hand and your smooth work surface. Placed seem side down on a baking sheet lined with parchment paper.
Brush lightly with egg wash and let them rest (ferment) again covered in a warm place for about 60 minutes or until they double in size. Brush again one final time with egg wash.
Bake at 375 degrees for approximately 20 minutes, until they are a dark golden brown
