Preheat the oven to 350 degrees.
Prep the cake pans with a coat of baking spray.
Sift the flour, sugar, cocoa, baking soda, baking powder, and salt into the mixing bowl until blended.
In another bowl, combine the buttermilk, oil, eggs, and vanilla.
With the mixer on low speed slowly add the wet ingredients to the dry ingredients. Continue mixing the ingredients on low adding the coffee,
Make sure that all of the ingredients are blended and include anything stuck to the bottom of the bowl.
Pour the batter into the two 8" pans . Bake at 350 degrees for 30-40 minutes. (Or until a inserted toothpick comes out clean)
When the cakes have baked remove them from the oven and set aside for at least 30 minutes to cool. Next, remove the cakes from the pans and transfer them to a cooling rack. Allow to cool completely.
