Blackbird Doughnuts hatched with a tiny space on Tremont Street in Boston (ironically, situated between a series of fitness centers) and now has shops in Fenway, Harvard Square, Newton Centre, and elsewhere, including the downtown food hall High Street Place. Owned by the folks behind South End spots Banyan Bar + Refuge and Sally’s Sandwiches, a madcap influence is evident in some of the more curious flavors in the rotating selection of doughnuts, such as Everything Bagel and nostalgic riffs on cider doughnuts. Brioche and cake doughnuts are on the menu—try the vanilla bean-glazed signatures side-by-side—as well as doughnut ice cream sandwiches. The original shop now shares space with Sally’s Sandwiches—and you can bet Blackbird Doughnuts are one of the breakfast sandwich bread choices.
