Tiffin is a form of cake-like confection composed of crushed biscuits (most commonly digestive biscuits), sugar, syrup, raisins and cocoa powder, often covered with a layer of melted chocolate. Unlike regular cakes, Tiffin does not require baking. Instead, following preparation of the mixture, the confection is chilled until set. As a consequence the product may also be known as 'fridge cake' or another similar term. It was invented in the early 1900s in Troon, Scotland.
The confectioner Cadbury produces a chocolate bar called "Tiffin", consisting of biscuit pieces and raisins in chocolate, as part of its Dairy Milk range.
