Which came first, (the) chocolate or (the) chestnut? Well who even cares when these two classic ingredients taste so good together, as exemplified by this holiday worthy cake. You can find fresh chestnuts in the produce aisle of any supermarket once November rolls around, and you'll need to roast these and then peel before grinding. Your house will smell spectacular. The chocolate is melted before mixing into the simple yet egg rich batter (meaning its super moist).
