An éclair is a French pastry made with choux dough filled with a cream and topped with a flavored icing. The dough is typically piped into an oblong shape with a pastry bag and baked until it’s crisp and hollow inside. Once cool, the pastry is filled with custard, whipped cream, or meringue, then iced with chocolate fondant. The word éclair in French means “flash of lightning,” so named because it’s eaten quickly (in a flash).
