Preheat oven to 350 degrees F. Grease 3 9-inch round cake pans. Place 9-inch parchment rounds on bottoms of pans and grease if desired.
In a large mixing bowl whisk together the granulated sugar, flour, cocoa powder, baking powder, baking soda, and salt until well combined.
Add eggs, milk, water, vegetable oil, and vanilla extract to bowl on top of other ingredients. Gently whisk the wet ingredients on top to just combine slightly and break eggs. Then whisk all ingredients together until just combined. It's ok if small lumps.
Divide batter between three pans. Bake at 350 degrees F for about 20-25 minutes or until toothpick inserted into middle comes out clean.
Remove cakes from oven, cool slightly, then remove cakes from pan to cool completely. Frost as desired.
