A profiterole, cream puff, or chou à la crème is a filled French and Italian choux pastry ball with a typically sweet and moist filling of whipped cream, custard, pastry cream, or ice cream. The puffs may be decorated or left plain or garnished with chocolate sauce, caramel, or a dusting of powdered sugar. Savory profiterole are also made, filled with pureed meats, cheese, and so on. These were formerly common garnishes for soups.
The various names may be associated with particular variants of filling or sauce in different places.
