A profiterole or cream puff (U.S.) is a food made from a small, round baked choux pastry filled with a sweet filling. The most common form nowadays is a dessert filled with whipped cream or pastry cream, and often served with chocolate sauce or a caramel glaze.
The origin of both the pastry and the name are obscure. The word (also spelled prophitrole, profitrolle, profiterolle)has existed in English since the 16th century. The original meaning in both English and French is unclear, but later it came to mean a kind of roll 'baked under the ashes'. A 17th-century French recipe for a Potage de profiteolles or profiterolles describes a soup of dried small breads (presumably the profiteroles) simmered in almond broth and garnished with cockscombs, truffles, and so on.
The current meaning is only clearly attested in the 19th century. The word originated in french, as a diminutive for "profit",or, "small gain." It is used for cream puffs and eclairs, which ARE french in origin.
