Stir in potato flakes. Let stand for 1 minute. 3. Add wet ingredients to dry ingredients with egg. Beat on low to medium speed for 30 seconds, scraping sides of bowl. 4. Beat on high for 3 minutes. Using a wooden spoon, stir in as much of the remaining flour as possible. 5. Turn dough out onto lightly floured surface.

On lightly floured surface, roll each half to 1/2-inch thickness. Cut with floured 2 1/2-inch round cutter. 11. Place roll in prepared baking pans. Cover and let rise in a warm place for 30-40 minutes, or until nearly double. 12. Preheat oven to 375 degrees. Bake for 15 to 20 minutes, or until golden. 13. Immediately remove rolls from pans.
