Napoleons are a type of French pastry that consists of layers of flaky puff pastry, filled with either pastry cream or whipped cream. Although there are no direct synonyms for the word napoleons, some similar French pastries can also be used to describe them. For example, an eclair is a long, tubular pastry filled with custard or whipped cream and topped with chocolate icing, while a pithivier is a round pastry filled with almond cream and often decorated with a lattice pattern. Other pastries that may be compared to napoleons include mille-feuille, which also uses layers of puff pastry, and cream horns, which have a similar filling of whipped cream.
