Top Tier Devil's Food Cake with Sour Cream Fudge Frosting

Our daughter L is at Grandma's this weekend, so my husband D is finding himself restless with his freedom. He couldn't decide what to do when his Saturday afternoon wasn't consumed with building a castle for the princesses or playing Snow White's Prince Charming. So I suggested he find something to cook. D likes to look through our monthly Bon Appetite magazines, find the gooiest, chocolatey-est thing in the magazine, and make it. He had his eye on this particular cake for a few days.
