Donna's Donuts in Tewksbury, Massachusetts, is offering a cheeseburger doughnut. There's no burger or cheese involved; it just looks like a cheeseburger:
...A chocolate honey-dipped (the "burger") is put inside the shell of a jelly donut (the bun) and slathered with Bavarian cream (the cheese) to create a sweet cheeseburger-lookalike.
Doughnut sandwich with two kinds of cream-smothered doughnut in every bite? Bring it on. It looks like Donuts with a Difference in Medford, Massachusetts, also makes a cheeseburger doughnut, as seen in this photo.
