The favorite myth, cited in Betty Crocker's Baking Classics and John Mariani’s The Encyclopedia of American Food and Drink, tells of a housewife in Bangor, Maine, who was making a chocolate cake but forgot to add baking powder. When her cake didn’t rise properly, instead of tossing it out, she cut and served the flat pieces. Alas, that theory relies on a cookbook published in Bangor in 1912, six years after the first chocolate brownie recipe was published by one of America’s most famous cookbook authors, Fannie Merritt Farmer, in 1906 (and the Bangor version was almost identical to the 1906 recipe).
