Classic Brownies

1. Preheat oven to 350 F. Grease an 8 inch square baking dish then set it aside.
2. In a saucepan over low heat, combine butter and unsweetened chocolate. Heat, stirring often, until melted, about 4 minutes.
3. Remove from heat and stir in the sugar and salt.
4. Then add the eggs and vanilla and stir until well blended.
5. Sprinkle the flour over the mixture and stir until just blended.
6. Pour the batter into the prepared dish and spread evenly.
7. Bake until a toothpick inserted into the center of the brownies comes out almost completely clean, about 25 minutes. Do not overbake.
8. Remove pan from the oven and let brownies cool completely in the pan.
9. Cut into squares.
