Buttermilk Chocolate Cake with Chocolate Cream Cheese Frosting
This is the chocolate cake I made most often when I began making more layer cakes from scratch. The buttermilk in the recipe gives this cake a tender crumb and light texture.
This is a fragile cake. It is helpful to put the cake layers in the refrigerator before frosting.
There are many good chocolate cream cheese frosting recipes, this recipe takes it up a notch by using melted chocolate. The melted chocolate makes it richer and oh so worth it.
I like to use three 8-inch round cake pans for this one but you could use 9-inch pans if you like. Keep in mind thinner layers with a 9-inch pan will be more delicate. Not a bad thing, just be sure to have a cake circle or large spatula nearby to make it easier to handle the layers.
Enjoy!
