I make my sponge cake a little differently to create my Buche de Noel or Yule Log cake. Using the basic sponge cake recipe, I lightly grease and pour the batter into a large sheet cake pan. I think pouring it over a parchment liner ibetter. When it tests done and is slightly cooled, I lightly sprinkle the surface with granulated sugar, and roll it up from the narrow end of the cake. I wrap it in a sugared towel (sugaring prevents sticking) and let it cool. When cool, I gently unwrap the cake, spread choc/brandy filling over all, (any kind of favorite filling can be used). At that time, I place it on the serving dish I'm planning to use for it, place parchment again under the edges of the cake to keep frosting off the platter, and frost the cake with chocolate frosting to resemble bark. I use a fork to create the rough bark design. Oops, forgot! Before I place the rolled cake on the platter, I carefully cut a 2-3 inch piece on the diagonal off one end. This becomes "cut limb" on my log cake. I attach this piece with the icing on the main log to look like an actual cut log for the fire. Frost all. Before serving, I lightly sprinkle the Yule Log with powdered sugar to resemble snow fall on the log, and tuck in a small piece of artificial holly at the attached "limb" location. I usually dust the platter with some of the powdered sugar for effect before showing off the completed Yule Log. This is just a fun way to use sponge cake for the Holiday, and lets you play in the kitchen to make something different for your family or guests. Oh, btw, I usually add a "touch" of a favorite alcoholic beverage to the filling and/or icing when I make this for Christmas. Artificial flavors could be used instead. ~G Oops again, Before I put the cake with te filling mixture spread on it on the serving platter prior to icing it, I reroll the now filled cake into it's log form, ready for the icing. Please forgive my confusing outline above...I've run into an editing glitch that makes it difficult to make a correction in the text of the writing. It's hard to go wrong doing a Yule Log. Have fun, be creative, and glow in all the compliments you receive when serving this dessert! ~G
