Pour warm milk into large bowl; stir in yeast until dissolved. Add 2 cups of the flour, granulated sugar, salt, and eggs; mix with electric mixer on low speed 30 seconds, scraping bowl occasionally. On medium speed, beat 2 minutes, scraping bowl occasionally. Add butter, 1 tablespoon at a time, mixing well after each addition. Stir in enough remaining flour, 1/2 cup at a time, to form dough easy to handle.
