Preheat the oven to 350F degrees & line muffin pans with muffin papers.
In a medium bowl whisk together the flour, cocoa powder, baking powder, baking soda and salt.
In a large bowl beat together the oil, sugars, eggs, vanilla extract & instant coffee granules.
Slowly beat in the flour mixture about ⅓ at a time, alternating with about ⅓ of the milk until combined. Turn off the mixer and scrape down the sides of the bowl as necessary.
Spoon the batter into the prepared pans, filling each cupcake liner about ⅔ full. You'll end up with 14-15 cupcakes total.
Bake for 15-18 minutes, or until an inserted toothpick comes out clean.
