My friend Sam is one of my bigger cake inspirations (see the "Welcome to Earth" cake). For his 30th birthday, I wanted to do something over the top with things he loves: Bears, Star Trek, sharks, and general badassery.
Sam helps run a distillery, so I was able to obtain some of his liquor to bake the cake with. The sheet cake was rum cake, and the volcano was chocolate bourbon cake. And the top of the volcano was filled with a shot glass of the rum, which I lit on fire before I brought it in.
