Preheat oven to 350 degrees F (175 degrees C). Grease and flour two 9 inch round cake pans.
In a medium bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt.
In a large bowl, cream together the butter and sugar. Beat in the eggs one at a time, then stir in the vanilla. Beat in the dry ingredients alternately with the buttermilk. Divide batter between the prepared pans.
Bake for 30 to 35 minutes in the preheated oven, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool for 10 minutes before removing from pans to cool completely.
