One legend about the creation of brownies is that of Bertha Palmer, a prominent Chicago socialite whose husband owned the Palmer House Hotel. In 1893 Palmer asked a pastry chef for a dessert suitable for ladies attending the Chicago World's Columbian Exposition. She requested a cake-like confection smaller than a piece of cake that could be included in boxed lunches. The result was the Palmer House Brownie with walnuts and an apricot glaze. The modern Palmer House Hotel serves a dessert to patrons made from the same recipe. The name was given to the dessert sometime after 1893, but was not used by cook books or journals at the time.
The first-known printed use of the word "brownie" to describe a dessert appeared in the 1896 version of the Boston Cooking-School Cook Book by Fannie Farmer, in reference to molasses cakes baked individually in tin molds. However, Farmer's brownies did not contain chocolate.In 1899 the first-known recipe was published in Machias Cookbook. They were called "Brownie's Food". The recipe appears on page 23 in the cake section of the book. Marie Kelley from Whitewater, Wisconsin created the recipe.
