First pour the condensed milk into a glass (0.25 l), then carefully pour the liqueur and then the brandy on top. Carefully pour the black coffee (can also be espresso) over the back of a teaspoon (this is done because of the optics so that the ingredients don`t mix). Finally, add spray cream or frothed milk and sprinkle with a pinch of cinnamon. Serve with a straw.
