In addition to Novel Sweets, you can find Cloud 9 Confections at 7th Street Market.
It seems they have more of a permanent set up that Novel Sweets does. While Novel has a stand that is set up each day in the middle aisle, Cloud 9 has a spot along the wall, complete with a display case and kitchen.
I’d stumbled upon their website a while ago, but it seemed they only worked weddings and other large-scale events.
