Tres Leches cupcakes are unqiue from others because they contain three different types of milk. Hence the name — translated into English, Tres Leches means “three milks.” In this particular recipe, the milks used are evaporated, condensed and heavy cream (although you can substitute coconut milk.) The rest of batter is made up up standard cupcake ingredients like eggs, flour and sugar. Instead of frosting, cut out a portion of the top of each baked treat and fill with a homemade meringue frosting that includes a pinch of cinnamon. Yummy!
