Common ingredients include buttermilk, butter, cocoa, and flour for the cake, beetroot or red food coloring for the color. In recent years, red velvet cake and red velvet cupcakes have become increasingly popular in the US and many European countries. A resurgence in the popularity of this cake is attributed by some to the 1989 film Steel Magnolias which included a red velvet groom?s cake made in the shape of an armadillo. Magnolia Bakery in Manhattan, having served it since its opening in 1996, helped to popularize it, as did restaurants known for its Southern cooking like Amy Ruth?s in Harlem, which opened in 1998. Cake Man Raven opened one of the first bakeries devoted to the cake, in Brooklyn, in 2000.
