National Devil's Food Cake Day is observed in the USA on May 19 each year. This day celebrates the rich chocolate cake known for its airy and moist texture, which emerged in the early 20th century as a counterpart to the white angel food cake. The first recipe for devil's food cake was published in 1905, although it likely existed earlier. The cake is characterized by its darker color compared to regular chocolate cake and often features a special coffee flavor, with cocoa added to the batter instead of chocolate. To commemorate the holiday, people typically bake devil's food cake, covering it with rich chocolate frosting to enjoy with family and friends.
