Vineyard/Grape-Themed Cake for a Birthday on Martha’s Vineyard Island

Proud of myself so I’m sharing. This is a yellow butter cake filled half with whipped dark chocolate ganache and half with lemon curd. Icing is Italian Buttercream. I had to transport this on a ferry — 2 hours 15 minutes in the car, 15 minutes waiting for the ferry, 45 minutes on the ferry and then a quick drive to the house. I froze it before the trip, packed it with a bunch of ice packs into a soft-sided cooler, then put it back in the freezer when I got there because we weren’t going to eat it for another 48 hours. I followed all advice on how to freeze, how to thaw, and how to bring it up to room temp, and it worked beautifully.
