White Christmas Rolls: My white Christmas

December = Christmas ^^, yes, it's the biggest event of the year.

This year, I will go to UK to celebrate Christmas with my sis, I really hope that it will be white Christmas, hehe. It will be cold but when thinking about tucking yourself in a warm blanket, sipping a cup of hot drink while looking at the snow ^^. It will be one of the best Christmas day, right?
So, to prepare myself, I thought about making Christmas yule log that presents my idea,  snow white roll cake is the best thing that came to my mind. 
Start with soft and fluffy white cake, that made from egg white, filled and covered with rich white chocolate mousse, and decorate with white chocolate, it's snow time!
This cake and mousse are very easy to make, but there are some points that you have to remember, first don't over bake the cake, as it will be dry and become crack when roll, second, when refrigerate the mousse before filling the cake, check frequently, you just want it to be thick enough to spread, and the last one, after filled and covered with mousse let the cake set for at least 12 hours, the cake will become moist from the mousse and it will be more delicious.
