A Piece of Cake

“A piece of cake” is an informal way to describe something very easy to do. A well-known early printed citation appears in Ogden Nash’s 1930s collection The Primrose Path, but an early citation is not proof that Nash coined the expression.

Quick answer

If a task is “a piece of cake,” it is very easy. The 1930s Nash citation is important chronology, but this engine treats it as documented early evidence rather than proof of coinage or proof that the expression came from cakewalks, prizes, or another specific custom.

What the evidence supports

Unresolved

Ogden Nash coined “a piece of cake.”

A Nash citation is a notable early printed example, but earliest located print evidence is not enough by itself to prove authorship or coinage.

Unresolved

The idiom directly derives from cakewalk competitions or cake prizes.

The semantic connection is plausible, but the reviewed sources do not establish a documented direct chain from that custom to this fixed idiom.

Further guidance

Coinage Boundary

Finding an early printed example establishes a terminus in the documentary record; it does not establish that the printed author invented the idiom.

Documented Citation

Phrase Finder identifies a 1930s Ogden Nash citation in The Primrose Path. The bibliographic record confirms the Nash collection, while the exact line is retained here as secondary-reported chronology rather than independently re-quoted from a full primary scan.

Meaning

Cambridge defines “a piece of cake” as something very easy to do and labels it informal.

Semantic Family

Cake, pie, cakewalk, and related pleasant/easy metaphors form a broader semantic family, but similarity is not sufficient evidence for a direct derivation.
