"A Marshmallow World" (sometimes called "It's a Marshmallow World") is a popular song that was written in 1949 by Carl Sigman (lyrics) and Peter DeRose (music). It was published the following year by Shapiro, Bernstein & Co. The song is about winter and is commonly regarded as a Christmas song, although the lyrics make no mention of the holiday. The song compares a snowfall to marshmallows covering the ground. It also describes the snowfall as whipped cream and the sun as a red pumpkin head. The singer "waits for it the whole year 'round."
