Where does A piece of cake come from?

Phrase Finder’s earliest citation is from the American poet Ogden Nash in The Primrose Path (1936): “Her picture’s in the papers now, And life’s a piece of cake.” English Wiktionary agrees it was originally American. Why cake means easy isn’t recorded; Wiktionary suggests a link to “cakewalk” or simply that cake is pleasant to eat, and English has plenty of easy pies and cakes besides.
