Blackbird Donuts is a must-go if you're into crazy donut flavors and designs (flavors rotate). Try the Purple Cow, the Guava Glazed, or their signature Blackbird donut (vanilla bean cake donut with vanilla glaze). On a hot summer day, pick your favorite donut and ice cream flavor and they'll make you a donut ice cream sandwich! Or better yet, order a whole donut-based cake! #Boston #sweets #donuts Photo obtained from the Blackbird Donuts public Facebook page.
