No founder or establishing record for June 26 has been located, and the Federal Register carries no document under the day's name. The earliest print appearance of the full name is a 2007 listing in a periodical called Creative forecasting, which dates the listing rather than the day.
The first one was baked
Go back far enough and a chocolate pudding is neither cold nor spoonable. The Food Timeline gives the earliest print reference it has found as 1730, in Charles Carter's The Complete Practical Cook, and the thing described is closer to a rich baked custard: eight eggs to a pint of cream, nutmeg and cinnamon and ginger, a quarter pound of grated chocolate, a little minced citron. Carter tells the cook to line the dish with puff paste and bake it, or boil it if you please.
