Alton Brown's cocoa brownie recipe is a simple and traditional recipe made by beating four large eggs until fluffy and then adding 1 cup each of white sugar and brown sugar. Add 1 and a quarter cup of cocoa, half a cup of flour, 2 teaspoons of vanilla extract and 2 sticks of melted butter and mix. Bake the batter in an 8-inch baking dish at 300 degrees Fahrenheit for 45 minutes, or until a toothpick can be inserted and removed from the center cleanly. Allow the brownies to cool before serving.
