Although both Sicily and Campania claim to have invented this popular pastry, the first diplomatico was said to have been made by the Duke of Parma's chef for the Duke of Milan Francesco Sforza, and hence its rather grand name.
Diplomatici are traditionally made with layers of pan di spagna, red alchermes (others use rum), crema diplomatica and pasta sfoglia and topped with powdered sugar and cut into squares, but there are many variations, including one using Nutella. Getting powdered sugar all over your clothes is an essential part of the experience.
