Oh the pressure of trying to find something "cool" for a 15 year old boy!!! :-)

Then I had this little spark - my son and most of his buddies are totally into the Little Big Planet 2 game, so I thought I would give it a try and this is the result. It was a great hit!

The bottom two layers are chocolate cake filled with chocolate mousse. The sack boy cake is butterscotch flavoured and a great complement to the chocolate. The whole cake was then covered in chocolate mousse. I added some icing sugar and cocoa powder to make the "knitted" effect on the top a little darker. The zipper, eyes and mouth are all cut from fondant.
