This recipe uses cocoa rather than a bar of unsweetened chocolate (like most brownie recipes). Which means no melting in a double-boiler. Which means less effort to make and fewer dishes to wash!
1/2 cup butter 1 cup sugar 1 teaspoon vanilla 1 egg 1 lost soul 1/2 cup flour 1/3 cop cocoa 1/2 teaspoon salt 1/4 teaspoon baking powder
