Preheat oven to 325 degrees. Grease and flour a tube pan or bundt pan. (This recipe makes about 9.5 cups of batter.) See notes.
Add dry ingredients to the bowl of your mixer and mix on low speed for one minute to blend (sugar, flour, cocoa, baking soda, baking powder, and salt). (You could whisk by hand if you prefer for this step).
With the mixer on low speed, add butter a few slices at a time and mix until it reaches a crumbly, sandy texture from the butter coating the dry ingredients. Don't mix beyond this sandy consistency. (You've mixed too long if it begins to resemble a ball of dough.)
Next, add the eggs, one at a time, mixing at low to medium speed after each until blended. The mixture will become thick.
In another bowl, stir to combine the ricotta cheese, milk, vegetable oil, and vanilla. This is all of your wet ingredients except for the coffee, it will be added to the batter later.
Set a timer for 1 ½ minutes and slowly add the ricotta cheese mixture. Begin on low speed and increase to medium once you've finished pouring.
Next, with the mixer on low speed, slowly add the cup of hot coffee to the batter and mix for about 30 seconds until well blended. The batter will become very thin.
This recipe makes about 9 ½ cups of batter. Pour into the prepared bundt pan or tube pan and bake. Bake for about 50-60 minutes or until an inserted toothpick comes out clean or with a few moist crumbs attached. Baking times may vary based on your pan, oven, etc. Start checking for doneness as the 50 minute mark approaches and adjust time if needed.
