The Origin of ‘A Piece of Cake’

The origin of the phrase ‘a piece of cake’ is unclear. However, here is how it might have developed into the idiom it is today:

It’s worth noting that a similar expression exists that goes ‘as easy as pie.’ Both sayings have identical meanings—they express simplicity, but why is that? Indeed, what is so simple about cake and pie? 

It probably doesn’t have to do with the cooking aspect. Why not? Because baking a cake requires a fair bit of work. For instance, you first have to buy all of the necessary ingredients for it. Then you have to do some measuring, pouring, and mixing together of everything in a bowl. After, the cake needs to be put into a preheated oven to start baking. Okay, so it’s not exactly the most difficult task, but I wouldn’t say it’s easy either. In short, I don’t think the origin of this idiom comes from making a cake.

However, what about the eating aspect? Yes, eating a piece of cake is very easy to do because, well, it’s delicious! So then, could it be the origin of this idiom comes from how easy it is to eat a piece of cake? That would be my guess.

Anyway, this phrase (with its figurative meaning) goes back to at least the 1930s. The term was used at that time by an American poet named Ogden Nash. He wrote a book called Primrose Path in 1936 and there is a part from the book that reads:

“Her picture’s in the papers now, And life’s a piece of cake.”
