Preheat oven to 325 and generously spray 2 round cake pans.
In a bowl, whisk together flour, salt, baking powder, baking soda, and cocoa powder.
In another large bowl, mix together sugar, oil, eggs, and vanilla.
Add dry ingredients to wet ingredients (be careful not to over-mix).
Add milk and coffee and mix again (batter will be quite watery!)
Pour batter into pans and bake for about 50 minutes or until a toothpick comes out relatively clean. Let cool completely before removing from pans
