½cupdark or semisweet chocolate pieces or chocolate chips
Instructions
Preheat oven to 350 degrees F. Line a 9x13 inch metal pan with foil and grease foil. Alternatively, use parchment paper or nonstick foil.
In a microwave safe bowl, combine the butter and chocolate. Microwave at 50% power, stirring ever 30 seconds, until mixture is melted and smooth.
In a large mixing bowl, gently whisk together eggs, both sugars, vanilla and salt. Stir in the melted chocolate mixture until fully blended, then fold in the flour.
Pour batter into the pan and bake on center rack for 30-35 minutes. Pull from oven and sprinkle chocolate pieces or chocolate chips over the top.
Let the brownies cool completely on a rack. Grasp foil, lift from pan, put brownies on a cutting rack and cut into 16 squares or 12 bars.
For a cleaner cut, chill brownies before slicing.
Notes
I like adding M&Ms right when the brownies come out of the oven.
