In the bowl of a stand mixer whisk together the yeast and water. Whisk in the sugar, oil, salt, eggs, and the mashed potato flakes if using.
Add the flour and knead for 6 minutes over low speed. Rest the dough for 10 minutes.
Transfer dough onto a floured surface and cut into 4 equal pieces. Cut each piece in half again to make a total of 8 pieces. Gently pat and roll into a 12-inch log.
