Tiffin

Tiffin is a form of cake-like confection composed of crushed biscuits , sugar, syrup, raisins, chocolate, and cocoa powder, often covered with a layer of melted striped 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. The confectioner Cadbury produces a chocolate bar called Tiffin, consisting of biscuit pieces and raisins in chocolate, as part of its Dairy Milk range.
