When sponge has cooled remove from pan and remove parchment paper from back of sponge. Place on top of new piece of parchment paper to build yule log.

Spread a smooth, thin layer of chocolate mousse over sponge. Then roll sponge into a log.  Move the log to a sheet pan lined with parchment paper. Then place in the cooler to let mousse set up. Also place all leftover mousse in cooler as this will be the icing for the outside of the log.

When mousse has set up and roll is firm, remove from cooler and cut off ends. Then make another cut on one side to remove a small piece to use as a decorative piece to the yule log.

Place cut piece on the side or on top of the yule log.  Place extra mousse into a pipping bag with a star tip. Pipe strips of the mousse along the yule log and on additional piece. If additional piece is on top pipe going up.
