Query: Does "piece of cake" (sth. easy) derive ultimately from "cakewalk"?

[Cohen, Gerald Leonard]

Is there any chance that "piece of cake" (something easy: HDAS: first attestation is 1936), which derives from slang "cake" (something easy; HDAS: first attestation is 1911) derives ultimately from "cakewalk" (easy victory in boxing; then: something easy;  HDAS: first attestation is 1897)?
