Preheat oven to 375°F and grease and flour an 8x8 inch baking pan.

In a medium bowl whisk together the eggs and sugar.

Slowly whisk in the melted butter and the vanilla extract.

Sift in the flour and cocoa and whisk just until blended.

Add batter to the prepared pan and bake for 1/2 an hour or until done.

Sift powdered sugar onto top of brownies, cool for 5 minutes, cut and remove to a wire rack to finish cooling.

Now hide a few from your kids before you tell them they're ready.
