In the bowl of an electric mixer, whisk the eggs to break the yolks. Add the milk, oil, and sugar. Whisk to incorporate. Add 2 cups of flour and yeast. Using the dough hook or by hand, mix the dough to incorporate the flour and yeast. Add the remaining flour and salt. Knead until it pulls away and cleans the side of the bowl but is slightly tacky, 6-8 minutes.
