chocolate  mousse

There is a bakery in town that sells the best cake ever. At least I think it is the best cake ever. My mom got me hooked on it many years ago. It is this rich chocolate cake that has layers of mousse and then covered in this thick rich chocolate icing.  Oh, and then it is covered with shaved chocolate.  
Can you say chocolate heaven?
Because if you can pick what heaven you go to, I want to go that heaven. I'll marry Willy Wonka and we will swim around in chocolate rivers forever. Then, we will spit chocolate into the air like the angry bird movie.  Okay, just kidding. But I do love chocolate, okay? So here is some mousse for ya! Do what you please with it. If you want to be really naughty, put it on ya ice cream.
I won't tell.
