Sioux City, Iowa’s Daily Grind is known for their terrific homemade cinnamon rolls (as well as, of course, their coffee drinks). But we just read about a variation on the cinnamon roll from Daily Grind that we’re anxious to try: the cinnamon roll cupcake. It’s made with a cinnamon batter and topped with cinnamon/sour cream frosting. One of those with a double espresso and our day in The Hawkeye State would be off to a grand beginning!
