Best Brownies

When I made the "fat-free" cookies for me the other day, I made these brownies for the kids. It's great because you can mix it all in the saucepan with a wooden spoon. No need to pull out the mixer. These are fudgy.
½ c. butter

1 c. white sugar

2 eggs

1 t. vanilla

1/3 c. unsweetened cocoa
