Tunis cake
A Tunis cake is a Madeira cake topped with a thick layer of chocolate and decorated with marzipan fruits. It is traditionally eaten at Christmas.
The origins of the cake are Edwardian. Scottish bakery Macfarlane Langs produced commercial Tunis Cakes in the 1930s, and when they merged with McVitie & Price in 1948 to form a company called United Biscuits the recipe passed to the new company. McVitie's produced a Tunis cake until the mid 1980s. It is now sold seasonally by some supermarkets in the UK. An early recipe does not include the chocolate and marzipan topping.
