Joe's Doughs sells their donuts on one or two Saturdays a month at The Daily Press in NoDa. Nowadays, there's always a crowd waiting for him to set up his table. I'm afraid to provide this info as i want people to stop showing up so I can have more for myself. They usually arrives at 9:30am so you gotta show up at least 15-30 min early and get ready for the wait, but it's so worth it.
The donuts are usually yeast but he will usually have one or two cake donuts. He does a good job of providing a good variety of donuts offering some standard flavors (chocolate caramel, almond glazed, s'mores) and some more adventurous ones (PB&J, Chicken and Waffles, Tiramisu). They range from $2-$3 and aren't overly huge which i prefer. You can order a couple to eat and you don't feel like a fatty after wolfing them down.
Cash and credit cards are accepted. Follow them on Instagram at @joedoughs so you know when he'll show up next as well the upcoming flavors for that day. Be sure to order to support The Daily Press by ordering their awesome coffee and teas as well!
