Preheat oven to 350 degrees. In a medium bowl, stir together the sugar, flour, cocoa, baking soda, baking powder and salt. Add the eggs, milk, oil and vanilla, mix for 3 minutes with an electric mixer. Stir in the boiling water by hand.
Bake for 17-20 minutes for cupcakes, or 30-35 minutes if making a cake. Either way, you know it is done when a toothpick inserted in the center comes out clean.
