These cupcakes sound yummy. Nigella describes them as "somewhere between chocolate and gingerbread." She has decorated them with white frosting, with two holly leaves made from ready-made, dyed icing and cranberries for the holly berries. I'm putting the recipe here so I know where it is at Christmastime. I don't know if the types of icings she uses are available here in the U.S., but you'll get the idea.
