Preheat the oven to 350 degrees. Grease 2- 9" cake pans and set aside.
Combine the sugar, flour, cocoa, baking powder, baking soda, and salt in a large bowl. Whisk to combine.
Add the eggs, milk, oil, and vanilla to a large measuring cup. Stir with a fork and mix into your dry ingredients until just combined. Fold in the coffee.
Divide your batter between your two prepared pans and bake 30 minutes or until a toothpick comes out clean.
Cool completely, frost, and enjoy!
