- Preheat oven to 350 degrees.   
- In a separate bowl, add the flour, sifted cocoa, baking soda, baking powder and salt. Whisk to blend and set aside. 
- In the bowl of your mixer, beat the softened butter on medium speed until light and creamy. Add the vegetable oil and vanilla extract.  
- Gradually add the sugar and mix until light and fluffy, approximately 4 to 5 minutes.  
- Add the eggs one at a time, mixing after each egg just until the yellow of the yolk has blended. Scrape down the sides and bottom of the bowl as needed. 
- Mixing on low speed, alternately add the flour mixture and milk to the sugar mixture, beginning and ending with the dry ingredients. (3 additions of dry ingredients and 2 additions of milk) Mix just until combined. 
- Add the cup of hot coffee at this time on low speed, mixing just until combined. The batter will be very thin. Don't worry this is how it should be. 
- If making cupcakes, scoop the batter (about ¼ cup per cupcake) into the cupcake liners and bake at 350 for about 16-18 minutes, or until the tops spring back when lightly touched or a toothpick comes out clean or with just a few crumbs attached. (Makes about 3 dozen cupcakes). 
- Makes approximately 8.5 cups of batter.
