Help me identify this dessert

So the restaurant that I work at uses a distributor that also supplies other restaurants, standard practice. So a while ago, they mis-stickered a case as avocado pulp, and upon opening it, we found out it wasn't. So it sat in the freezer for a few months before we got curious enough to thaw it out and figure out what it was.

So what it is:

bottom layer is chocolate devils food cake
then a layer of possibly mocha or fudge flavored mousse
then a layer of milk chocolate mousse
a thin layer of dark chocolate frosting
with chocolate curls on top.

So, because I don't know what store this should have gone too, nor the desserts name, nor the correct portion size, I don't know how to record it.

Have you eaten this and where? And how big a portion did you get?
