Île flottante or floating island is a popular dessert originating from France, consisting of meringues that are poached in vanilla custard and often topped with caramel sauce and toasted almonds. The meringues are usually made from whipped egg whites, sugar, and vanilla extract.

This classic dessert is one of the staples of French comfort food, although it is popular internationally, sometimes with small tweaks and variations, in countries such as Austria (Schneenockerln), Hungary (Madártej), Croatia and Serbia (šnenokle), and Italy (uova di neve).

In France, it is usually served in bistros, canteens, and hip restaurants. Although it is an extremely popular dessert, its inventor still remains unknown. Light, fluffy, and low in fat, floating island is believed to taste the best when served cold (or in some cases, at room temperature) after a big meal, although it can be consumed on its own, as a tasty mid-day treat.
