Tunnock's Caramel Wafer

The Tunnock's Caramel Wafer, correctly known as the Tunnock's Milk Chocolate Coated Caramel Wafer Biscuit, is a bar consisting of five layers of wafer, interspersed with 4 layers of caramel. The bar is coated in chocolate, made from cocoa and milk solids. The wafers are wrapped in red and gold coloured foil. Dark chocolate wafers, wrapped blue and gold, are also available.
In many small outlets they are available separately. The wrappers of the milk chocolate version bear the wording "more than 5,000,000 of these biscuits made and sold every week".
St. Andrews University has a Tunnock's Caramel Wafer Appreciation Society, founded in 1982.
