In a bowl, whisk together the flour,cocoa powder, baking powder, salt and sugar.

In another bowl, whisk together the milk eggs and vanilla.

Add the flour mixture to the egg mixture and whisk together just until combined. Then stir in the melted butter.

Cook batter according to your waffle maker instructions. I use ½ batter for my regular waffle iron and 1 cup for my Belgian waffle maker. Makes 6 regular waffles or 3 Belgian waffles.
