Preheat oven to 350°F.
Grease two 9" round cake pans and line the bottom with parchment paper.
Add flour, sugar, cocoa powder, salt, baking powder and baking soda to your mixing bowl (I use a stand mixer with the whisk attachment). Stir until combined.
2 cups all-purpose flour, 2 cups sugar, 3/4 cup cocoa powder, 1 teaspoon salt, 1 teaspoon baking powder, 2 teaspoon baking soda
In a medium bowl, whisk together the oil, buttermilk, eggs and vanilla.
1/2 cup vegetable oil, 1 cup buttermilk, 2 eggs, 1 teaspoon vanilla
Pour the wet ingredients into the dry ingredients and stir slowly until combined.
Add the coffee slowly. Then mix on high for two minutes, scraping the sides halfway through.
1 cup hot coffee
Distribute the batter between the two prepared pans.
Bake for 35-45 minutes, or until a toothpick comes out clean. (A few moist crumbs sticking to the toothpick is fine, but you don't want it gooey).
Cool for a few minutes. Run a butter knife around the outside of each pan, and turn the cakes out onto a cooling rack.
Make one batch of Glossy Chocolate Frosting (recipe link below) and frost the cooled cake layers.
