"Fragrant with cinnamon and enriched with a cream-cheese glaze, these morning buns make an unforgettable breakfast. Mashed potato is the secret behind their light texture, while bread flour provides structure and chew. It might be tempting to enjoy the rolls straight out of the oven, but be sure to let them rest at least 20 minutes before serving--this completes the cooking process and yields tender and airy, not gummy, buns...."
