I'm making some homemade oreos for a holiday party next weekend and I'd love to use the really, really, REALLY dark cocoa powder King Arthur sells online. Problem is I'm all out and I'm not sure it would get here in time if I order more. Soooo, anyone know of a bricks-and-mortar source in the 5 boros? I've checked the place on 22nd St and The Sugar Room in Sunnyside, no luck. Thanks.
