very, very adult chocolate tart

This was B1s request for birthday cake. It followed a very favourite baked chicken, proscuitto and mozarella dish that i know from memory but can no longer locate since my move-in with the Bloke and I lost my Foods of the World Time Series cookbooks. If anyone has the Italian small companion recipe book I'd love you forever if you could tell me what this dish is called. Its floured, flattenned chicken breasts, gently sealed and browned, then topped with proscuitto and mozarella and baked in stock until it looks just perfect. Its moist and delicious and when we have it (birthday dinners) I always serve it with hasselback potatoes and beans/brocollini.
So the choc tart was the only thing I remembered to photograph, well that and the risotto balls I made for the vegos amongst us but...another post...
