Preheat oven to 350, or 325 for a non-stick pan.
Spray a 12 inch pizza pan with non-stick spray.
In a medium size saucepan melt butter, sugar, and unsweetened chocolate over low heat, stirring frequently, until all melted and smooth.
½ cup butter, 1 cup sugar, 2 ounces unsweetened baking chocolate
Add in vanilla and stir to mix.
½ teaspoon vanilla
In a large mixing bowl combine flour and salt.
¾ cup all-purpose flour, ¼ teaspoon salt
Pour chocolate mixture in with the flour and thoroughly mix.
Add in eggs and mix until well incorporated.
2 eggs
Pour mixture in prepared pan and spread evenly.
Bake for 15 minutes, or until a toothpick inserted into the middle comes out clean. This is a very thin brownie so don’t overbake!
Remove from oven and place on a wire rack to cool completely.
