Preheat the oven to 175°C (350°F) and line a cupcake pan with paper liners. Sift the flour, cocoa powder, baking powder, baking soda, and salt in a medium bowl. In a large bowl, cream together the butter, white sugar, and dark brown sugar until light and fluffy. Beat in the eggs one at a time, followed by the vanilla extract. Gradually mix in the dry ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined. Divide the batter among the cupcake liners and bake for 18-20 minutes or until a toothpick inserted comes out clean. Allow cupcakes to cool completely on a wire rack.
