Incredibly chocolatey. From the Syllabub blog at blogspot.com. Ounce amounts are BY WEIGHT, not volume. Use the best bittersweet chocolate you can get, and grate it superfine - don't cut corners!
Made as written, in a Bundt pan, try serving it with the center filled with raspberries and lightly-sweetened whipped cream. You could also bake it in round cake pans, fill the layers with recipe #292600 (try splitting each layer in half to make four thin cake layers and three layers of buttercream) and douse the whole thing in recipe #292602. Don't put buttercream on the top and sides if you're using the ganache!
