Here is my version. Not as perfectly neat, but it tastes amazing.
Have fun making this to impress family and friends with this modern twist on a classic bûche de Noël stolen from Fine Cooking Magazine.
This delightful looking cake was featured in the December edition of Fine Cooking, one of my favorite magazines. I stole the photo from the article but will post mine tomorrow when it is decorated.
The layers are vertical rather than horizontal, making for a very dramatic reveal. It is an “all-day” project or one you can do over several days.

This version looks cool, but all the classic elements and flavor pairings are here, so it’s guaranteed to be delicious. The vanilla sponge cake has a delicate texture, yet it’s sturdy enough to “literally” stand on end. The layers are doused with a boozy soaking syrup before they’re coated with a smooth-as-silk, espresso-spiked white chocolate ganache filling and coated with a dreamy, creamy and eggless double-chocolate buttercream.
Like the traditional bûche, the garnishes for this cake can be rustic, whimsical, or elegant. I like to use the tines of a fork to create a barklike design in the buttercream around the side of the cake. Just before serving, I may top the cake with a cluster or two of small meringue mushrooms along with chocolate shavings for bark. You can add silver or white dragées for ice crystals, sugar-coated cranberries for a pop of color, a mint sprig or two for signs of spring, chopped pistachios for lichen, and a dusting of confectioners’ sugar for snow. Extra meringue mushrooms look great arranged around the base of the cake.
While the garnishes make the cake look spectacular, what people really want to know is how I make those magical vertical layers.
All in all, it’s a straightforward process: You use what could be called a “wrapping” technique to assemble the cake. After baking the sponge cake in a large rimmed baking sheet, cut it into five strips. To train the shape of the innermost strip of cake and avoid cracking in the final product, I roll up one strip in paper towels while it’s still warm, just as you would when you’re making a jelly roll. I then roll the remaining strips up in a tight spiral together to train them. The ends of these strips are cut on an angle to create beveled edges; this step helps the strips to lie flat as the cake is assembled.
Start building the cake by brushing the innermost strip with soaking syrup then coating it with white chocolate espresso ganache. After this centerpiece is rolled and positioned on a plate, brush, fill, and wrap the remaining four beveled cake strips one at a time around it. The technique sounds complicated, but as you’ll see, it’s an easy-to-follow
