Spalding's Bakery — Lexington, Kentucky
Probably one of the older mom-and-pop shops on this list, Spalding's Bakery has been serving mouthwatering, fresh glazed donuts since 1929 and counts three generations of Spalding's running the place. What's more, Joyce Leverett, who has been alive and working in the bakery since childhood, is still taking orders behind the counter today, at 90 years old. If you get the chance to visit this iconic Lexington, Kentucky bakery, whatever you do, you have to order an original hand-cut, honey-glazed donut. Be prepared to wait, though—there's pretty much a line all day long.
