I followed the recipe very carefully, after all, this was my first time doing a gluten free Bûche de Noël. I wasted 2 hours right before Christmas making this disgusting log. A log's frosting should be butter cream, period! The frosting in not even light, it is sticky and the coffee flavor too strong. Then the recipe tells you to put this mixture of brewed coffee and half and half over the sponge cake, get ready! It defies the purpose of having a "sponge cake" that is airy and light, by making it wet and heavy. The cake ends up collapsing and your log will look like a ridiculous plank! Had I only read the other reviews before starting this, I would have saved myself some precious time and much needed pre Christmas time. I am sooo disappointed! Don't make, don't even try, save yourself time and energy and find another recipe!
