cakewalk = a piece of cake

The cakewalk was a pre-Civil War dance originally performed by slaves on plantation grounds. The uniquely American dance was first known as the “prize walk”; the prize was an elaborately decorated cake. Hence, “prize walk” is the original source for the phrases “takes the cake” and “cakewalk.”
