In English you might call it a Yule Log, in France it's called a Buche de Noel, but in Italy it's
il Tronchetto di Natale. Here is my version I made a few years ago for Christmas. They are really easier than you think to put together... a simple sponge cake (yellow or chocolate--your choice), a filling, some icing and lots of fun with the kids scraping with spoons and forks to you think it looks like a real log in an early winter's forest. The only technical part that needs some attention is learning how to rold the jellyroll cake. (There are many Youtube videos if you need help).
In my version, I added holly leaves made from fondant with berries and mushrooms made from marzipan. A dusting of decorative or confectioner's sugar for a light snowfall and you're transported into the Italian Alps. I've included a basic recipe to make your own. If you have kids, by all means include them, especially with the decorating and Lucas' favorite thing... licking the beater...
