A Yule Log to get you in the Spirit!

The pleasure of cooking and baking during the holiday season is that we get to indulge  ourselves.  Celebrating the holidays with those you love and sharing the wonderfully decadent and full flavored food of all sorts is what makes this time of year extra special.

Yule Log full of Spirit! (Dark Rum)

Yule Log full of Spirit! (Dark Rum)

What could be more special that a Yule Log (Bûche de Noel) to share!  A light and tender Vanilla Sponge cake layer, soaked with Dark Rum Simple Syrup, filled with a Toasted Walnut & Dark Rum Buttercream, and then rolled up.  Cut and shaped into a log and then topped with a Rich Chocolate Buttercream and then finished with Meringue Mushrooms and Fondant Holly.  Did I say there is Dark Rum in this?  

Know each of the recipes for the Yule Log can be made ahead and stored until you are ready for assembly.  The flavor is much better if you make this a few days a head and store in a container at room temperature.  If you want or need to refrigerate the Yule Log make sure to bring it to room temperature before serving!
