Sift (or whisk) together granulated sugar, cocoa powder, flour, salt, and baking powder in a large bowl.

Stop here if you wish to make the brownies.

Preheat the oven to 350°F and prepare an 8x8inch pan with non-stick spray.

Melt butter and set aside to cool.

In a medium bowl, beat two eggs and vanilla extract with a hand-held mixer.

Add the egg mixture and melted butter to the dry ingredients. Stir until just incorporated.

Pour batter into the prepared pan and bake for 20-22 minutes.
