Knead has the best approximation of a mom and pop donut shop menu here although it is pricey. They have a good basic glazed and decent cake donuts. I have tried every donut shop in the state and they are not the same as what I imagine you are looking for. Been looking for years and unfortunately you won’t find it. The northeast in general is a tough market for donuts- Dunkin’ has such a stranglehold on the entire region. The closest I have found in the entire northeast overall is Peter Pan but that’s in NYC.

The Wax Witch- technically in Pawtucket but she does a very good job. Can be a little hard to get an appointment because it’s a popular place but for good reason.
