A Swiss roll, jelly roll (United States), roll cake, cream roll, roulade or Swiss log is a type of rolled sponge cake filled with whipped cream, jam, icing, or any type of filling. The origins of the term are unclear; in spite of the name "Swiss roll", the cake is believed to have originated elsewhere in Central Europe, possibly Austria^[1] or Slovenia.^[2] It appears to have been invented in the nineteenth century, along with Battenberg cake, doughnuts, and Victoria sponge.^[3] In the U.S., commercial snack-sized versions of the cake are sold with the brand names Ho Hos, Yodels, Swiss Cake Rolls, and others. A type of roll cake called Yule log is traditionally served at Christmas.

The spiral layered shape of the Swiss roll has inspired usage as a descriptive term in other fields, such as the jelly roll fold, a protein fold, the "Swiss roll" metamaterial in optics, and the term jelly roll in science, quilting and other fields.
