A Joffre cake (Romanian: prăjitură jofră) is a chocolate buttermilk layer cake filled with chocolate ganache and frosted with chocolate buttercream originally created at Bucharest's Casa Capșa restaurant, in honor of a visit by French Marshal Joseph Joffre, shortly after World War I. The cake is said to have been devised so as to be suitable for diabetics, as Joffre was diabetic.
Some commentators say the size of the Joffre cake probably had as a model the Adrian helmet worn by French and Romanian soldiers during World War I.
