This French cake known as a 'Buche de Noel' or to us a Yule Log is named so because the rolled cake actually does look like a yule log.
There are two separate amounts of cocoa and of sugar. The recipe is unclear as to which amount goes where. My cake broke on rolling and it stuck to the tea towel. I ended up putting it all in the freezer and mixing the cake and filling together to make a pretty good chocolate ice cream. - 14 Dec 2016
