½teaspoonsalt(decrease to ¼ if using salted butter)
1teaspoonvanilla
1cupall-purpose flour or bread flour(140 grams)
1handfulchocolate chunks (optional)
Instructions
Preheat oven to 350 degrees F. Line an 8 inch pan with foil and grease bottom only. Alternatively, if you love edge pieces you can line two 8 ½ by 4 ½ inch loaf pans with foil and bake two "loaves" of brownies
Put the chocolate and butter in a microwave-safe mixing bowl. Microwave at 50% power for about 2-3 minutes, stopping to stir every minute until melted and smooth. If you prefer to use the stovetop, just do this step in a 3 quart saucepan over very, very low heat.
Whisk in the sugars, then add each egg one at a time, followed by the salt and vanilla. Add the flour and mix well with a heavy duty rubber scraper.
Pour into the pan (or pans) and scatter some chocolate chunks on top.
Bake at 350 degrees F for about 40-45 minutes if using a square pan, or 35 if using a loaf pan. You'll know they're ready when the top appears cracked. Baking thick brownies like these sometimes involves trial and error. My loaf pan versions are always done after 35 minutes, at which point their internal temperature reaches 210 (it tops out there, so it will be 204 or something and climb).
Let cool completely, then remove from the pan and cut into squares.
