Dense and fudgy, these are the best brownies in the world.
1 cup butter or margarine, softened

Heat the oven to 325 degrees F. Grease a 12 x 9-inch pan.
In the large bowl of an electric mixer, cream the butter. Add the eggs, one at a time, beating well after each addition. Add the Double-Fudge Brownie Mix and continue to beat the mixture until it is smooth. Spread the mixture into the greased pan, and bake for 40 to 50 minutes.
