Celebrated on December 8th
No one knows for sure where the name "brownie" came from. Some say it was from a children's book. Eventually the term came to describe Girl Scouts, a Kodak camera, and the tasty treat.
One of the most popular stories about the origin of the brownie is told in the Encyclopedia or American Food and Drink, which reports that a housewife in Bangor, Maine forgot to add baking powder to her brownie, and therefore her batch didn't' rise properly. Ever the impeccable host, she carried on and sliced her now invented brownie and served it unashamedly, claiming her new invention.
The largest brownie ever made was at the Hudson Valley Chocolate Festival and Holiday Crafts Show in Suffern, New York, in Late 2001. Using 750 lbs. of melted chocolate chips the mammoth brownie weighted in at 3,000 lbs.
