Uber-Chocolate Father's Day Cake

My dad has been requesting a salted dark chocolate cake for a while now, so I decided to whip one up for Father's Day (what better occasion?).  Sweetapolita, as always, provided a beautiful recipe  that I shrunk and barely modified.  When (not if!) I make this again, I'd love to throw in some of the salted caramel buttercream in the middle to lighten everything up.  As it was, this was a big, gorgeous, totally delicious brick of a cake, with enough chocolate to kill a lesser human.  Dad loved it.  (This one also gave me an excuse to buy some fancy sea salt flakes, which were delicious and I'm going to put them in everything now.  I only wish I'd studded them around the sides of the cake as well as the top, to spread the flavor around!)
