I think the first time I saw this recipe in Cook’s Illustrated, my jaw dropped – literally.  I had seen several pictures of similar desserts around the interwebs and it sounded amazing, but none of the recipes seemed totally reliable to me.  Well, reliability has never been an issue when it comes to Cook’s Illustrated so I knew right away that I had found “the one”.  I also knew that this is exactly the sort of thing can render my will power useless, so I would have to have an occasion to serve it with lots of people around to enjoy it with me.  Our “yay for one mortgage” party seemed like the perfect opportunity to finally try it.  It was everything I was hoping it would be.

The bottom layer is a sort of flourless chocolate cake, the middle layer is a silky chocolate mousse and the top layer is a light yet rich white chocolate mousse.  Yum, yum, and yum!  My only (very tiny) complaint about this dessert was that after baking and cooling, the bottom layer retracted away from the sides of the pan so much that when the second layer of mousse was spread over the top, it filled in the gaps.  From the outside before cutting, it appeared to be only a double layer cake.  I know this is a trivial issue, but it really bothered me.  Of course, once I took a bite I couldn’t have cared less about that.  Once it is sliced, all three perfect layers show beautifully and topping with chocolate curls completes the look.
