Ultra-chocolatey and rich thanks to the fact the batter contains both cocoa and dark chocolate. First, you need to sift the dry ingredients. Separately melt the chocolate; when it's cooled down, add the eggs and combine the wet and dry ingredients. Though the recipe doesn't call for it, the cake would be all the better with a shower of confectioner's sugar on top. To really set it over the edge, serve a fruit coulis alongside.
