As much as I love chocolate, I love cookies more. However, I have come to love buttermilk and making a buttermilk chocolate cake just can't get any better. Especially when it comes to baking at a high altitude this buttermilk chocolate cake is the best. It is moist, rises well, and while it is chocolaty, it is not overwhelming at all. Of course, I embellished the chocolate in this cake with a layer of hot fudge and chocolate mouse and then covered the whole thing in a lovely shiny chocolate glaze. All eaters were pleased with the end result of a quadruple chocolate cake that wouldn't overwhelm you at all.
