Piece of cake

When something is exceptionally easy it is often called a piece of cake, or a cakewalk.

The term is said to have originated from slaves doing a dance called "cakewalking," a dance to somewhat imitate intricate ballroom dancing but made to look effortless. Slave owners would sometimes reward the best performer with a piece of hoecake.

Hoecake (pictured) is thin unleavened johnnycake or cornpone made of cornmeal. It gets its name because it was often baked by field hands on the blade of a hoe over an open fire.
