In a large mixing bowl, whisk together flour, granulated sugar, cocoa powder, baking soda, baking powder and salt. Add buttermilk, brown sugar, eggs, oil and vanilla. Beat with an electric mixer on medium speed for 2 minutes. Whisk in hot coffee until completely incorporated. The batter will be quite thin. Pour the batter into the prepared pan.
