The Bourbon biscuit is a sandwich biscuit consisting of two thin rectangular dark chocolate-flavoured biscuits with a chocolate buttercream filling.The biscuit was introduced in 1910 .The Bourbon name, dating from the 1930s, comes from the former French royal House of Bourbon. A 2009 survey found that the Bourbon biscuit was the fifth most popular biscuit in the United Kingdom for dunking into tea.The small holes in bourbon biscuits are to prevent the biscuits from cracking or breaking during the baking process, by allowing steam to escape.Bourbon is best enjoyed with your friends or BFFs during exciting adventures, daily classroom chitchatting sessions or at your favourite hangout spots!
