I made it just as her recipe directs, but I added 3 oz melted bittersweet chocolate and the zest of one orange. For the drizzle bit I used 1 oz melted bittersweet choc,icing sugar and in place of warm lemon juice, Grand Marnier.
My dh made slightly inappropriate sounds while eating it, but said although he thinks it's divine it's not "better than sex". I'm not sure, myself...chocolate cake runs a good race with sex in my book.
