A croquembouche or croque-en-bouche is a French dessert consisting of choux pastry puffs piled into a cone and bound with threads of caramel. In Italy and France, it is often served at weddings, baptisms and first communions.

The name comes from the French phrase croque en bouche, meaning "[something that] crunches in the mouth."

A croquembouche is composed of profiteroles piled into a cone and bound with spun sugar. It may also be decorated with other confectionery such as sugared almonds, chocolate, and edible flowers. Sometimes it is covered in macarons or ganache.

The invention of the croquembouche is often attributed to Antonin Carême, who includes it in his 1815 cookbook Le Pâtissier royal parisien, but it is mentioned as early as 1806, in André Viard's culinary encyclopedia Le Cuisinier Impérial, and in Antoine Beauvilliers' 1815 L'Art du Cuisinier. In Viard's encyclopedia and other early texts (e.g. Grimod de La Reynière's, Néo-physiologie du gout), it is included in lists of entremets—elaborate dishes, both savory and sweet, that were served between courses during large banquets.
