Todd, what you are probably looking for is an old franchise location that still makes donuts from Dunkin's mixes on-site. These days, Dunkin also has central bakeries which serve scores of stores from a central location. They also have bake-off shops, which start with frozen dough. They bake the dough, then finish them by injecting jam, putting on sprinkles, etc.
Hopefully some regulars here will know which Dunkin shops still bake from scratch in the areas you will be in. I don't even know which local shops around here still bake in the back. I have not checked recently on surburban shops which I know baked from scratch back in the day. A lot closed down. A stand-alone is no longer a guarantee they baked from scratch, but they probably have a larger selection.
If the online store locator shows a BR, for Baskins Robbins ice cream, this is probably a larger location than a convenience store or gas station.
Another thing to know is that new franchisees have to open 5 stores. So, if there are 5 stores in a town, they will all be the same!
