cake recipe?

[bld disney]

Does anybody have the chocolate cake recipe from the Boulangerie Patisserie? At one time, they also served it at Chefs de France. I've been searching in vain. I'd put in a request for it at the restaurant at one time and they said they'd send it but never did. My son loves it and I wanted to make it for his birthday next week.
I'd greatly appreciate the actual recipe or a good copycat!
Thanks.
