A Yule Log is a traditional Christmas dessert eaten in several different countries including the UK, France, Belgium, Switzerland, Canada and Lebanon. It is also sometimes known by its French name, bûche de Noël. A Yule Log is a sponge cake that's rolled and filled and covered with buttercream. It is decorated to resemble an actual Yule log by using a fork to create a jagged pattern on the surface of the buttercream. Chocolate is the most common flavour, but it can come in other flavours too. Making a gluten-free, vegan and refined sugar free roll cake that would actually roll was impossible! After several failed attempts, I decided it would be easier to make one by stacking three rectangular sponges on top of one another to make a log shape instead of using a roll cake as the base.
