Krumpe’s Do-Nuts is a Hagerstown bakery known for making fresh doughnuts overnight and serving them from its Maryland Avenue shop and regional delivery routes. The family business traces its roots to Rudolf Krumpe’s first doughnut shops in the 1930s and has remained a multigenerational Hagerstown tradition, with the current company incorporated by his grandsons in 2001. Its late-night storefront and annual Donut Alley Rally—held to benefit wounded-warrior organizations—are distinctive parts of the local institution.
