<P> Shoofly pie began as a crust-less molasses cake called Centennial cake in 1876, to celebrate the 100th anniversary of the signing of the Declaration of Independence in Philadelphia . In the 1880s, home bakers added a crust to make it easier to eat alongside a cup of coffee in the morning, without plates and forks . Precursors include Jenny Lind cake, a gingerbread cake from the middle of the 19th century . </P> <P> Because the cake contains molasses but no eggs, historians conclude that it was typically baked during the winter, when chickens laid no eggs but when molasses would store well in the cold weather . The use of baking powder places its invention firmly after the Civil War and in the 1870s, when Pennsylvania Dutch bakers began using baking powder . </P> <P> The name comes from a particular brand of molasses, Shoofly Molasses . This brand was named after a popular circus animal that toured in Pennsylvania in the 19th century, Shoofly the Boxing Mule . The mule, in turn, may have been named after a song that became popular half a century before: "Shoo Fly, Don't Bother Me". </P>
