Preheat your oven to 350°F (175°C) and prepare two 9-inch round cake pans with cooking spray and parchment at the bottom.

In a large mixing bowl, sift together the dry ingredients: sugar, flour, cocoa powder, baking powder, baking soda, and salt.

In another bowl, whisk together the wet ingredients: eggs, buttermilk, coffee, vegetable oil, and vanilla extract until smooth.

Gradually combine the wet mixture with the dry ingredients using an electric mixer until smooth and glossy.

Divide the batter evenly between prepared pans and bake for 30 to 35 minutes, checking for doneness with a toothpick.

Cool the cakes on a wire rack for 10-15 minutes before inverting to cool completely.

Prepare the frosting by mixing cream cheese, unsalted butter, and vanilla until smooth; gradually add powdered sugar.

Assemble the cake by frosting between layers and on top of the cake.
