Profiteroles are little pastries of which cuisine?

A profiterole, cream puff (US), or chou à la crème is a filled French 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.

Choux pastry dough is piped through a pastry bag or dropped with a pair of spoons into small balls and baked to form largely hollow puffs. After cooling, the baked profiteroles are injected with filling using a pastry bag and narrow piping tip, or by slicing off the top, filling them, and reassembling. For sweet profiteroles, additional glazes or decorations may then be added.

Choux pastry, the key ingredient of profiteroles, is said to have been invented by the head chef to the court of Caterina de' Medici (queen consort of France from 1547 until 1559), who had come to France from her native Florence to marry Henry II.
