Made last night for B's birthday dinner -- deep dark chocolate flavor, very moist yet still a bit cakey texture. Raves all around. Easy and quick to make, and uses pretty much standard pantry ingredients: chocolate, butter, eggs, vanilla, sugar, all-purpose flour. And no frosting or filling, so no chance of the slumpy vomitous layer cake syndrome which has afflicted my last 3 birthday cakes. (i'm just a loser.)
chocolate fallen souffle cake from February Gourmet chocolate article. The chocolate layer cake from this article was also excellent and intensely chocolatey, which I find rare in cake.
