Devil's foo cake is a rich, chocolate layer cake. Devil's food cake is aptly considered a counterpart to angel cake, that is the two cake types are very different: aside from being chocolate-flavored, devil's food cake incorporates butter (or a substitute) and far less egg. Both cakes were introduced in the United States in the 20th century. The recipe for this cake was first printed in 1905. Devil's-food cake is a type of butter cake. Unlike chocolate cakes using only cocoa, though, the inclusion of melted chocolate gives devil's food cake a higher fat content. Real chocolate is typically what distinguishes a 'devil's food cake' from a chocolate cake. The cake is usually paired with a rich chocolate frosting.
