Trifle is a layered dessert of English origin. The usual ingredients are a thin layer of sponge fingers or sponge cake soaked in sherry or another fortified wine, a fruit element (fresh or jelly), custard and whipped cream layered in that order in a glass dish. The contents of a trifle are highly variable and many varieties exist, some forgoing fruit entirely and instead using other ingredients, such as chocolate, coffee or vanilla. The fruit and sponge layers may be suspended in fruit-flavoured jelly, and these ingredients are usually arranged to produce three or four layers. The assembled dessert can be topped with whipped cream or, more traditionally, syllabub.

The name trifle was used for a dessert like a fruit fool in the sixteenth century; by the eighteenth century, Hannah Glasse records a recognisably modern trifle, with the inclusion of a gelatin jelly.
