Swiss roll
"Pianono" or "pionono" is a rolled version of the "mamón". It is typically sold as "cake rolls" in modern times due to its resemblance to the Swiss roll. Originally, its filling was composed only of sugar and butter or margarine, like all other kinds of "mamón". It is also traditionally much smaller in diameter than Swiss rolls. But modern versions are larger can vary significantly in the fillings and are usually frosted.
