Preheat your oven to 350 degrees
Prepare two 9 inch cake pans by lightly greasing and lining the bottoms with parchment paper. Set aside for now
Combine 9 ounces of cake flour, 2 cups of granulated sugar, 3/4 cup of unsweetened cocoa powder, 2 teaspoons of baking powder, 1 1/2 teaspoon of baking soda, 1 teaspoon of salt, 2 teaspoons of espresso powder in a large mixing bowl
Add 1 cup of buttermilk, 1/2 cup of vegetable oil, 2 large eggs, 1 tablespoon of vanilla extract into the dry ingredients and mix until fully combined
Add 1 cup of hot freshly brewed coffee and careful mix until the batter is smooth and thin
Divide the batter between two prepared 9 inch round cake pans
Tap the cake pans on the counter top to work any air bubbles to the surface
Bake on a center rack at 350 degrees for 30-35 minutes or until a toothpick comes out from the center of the cake clean
Transfer the pans onto a cooling rack for 5 minutes before transferring the cakes directly onto the cooling rack to cool completely
