16 tablespoons (2 sticks) unsalted butter
8 ounces bittersweet or semisweet chocolate, cut into 1/4-inch pieces
4 large eggs
1/2 teaspoon salt
1 cup granulated sugar
1 cup firmly packed dark brown sugar
2 teaspoons vanilla extract
1 cup all-purpose flour
One 13 x 9 x 2-inch pan, buttered and lined with buttered parchment or foil
Recipe
Set a rack at the middle level of the oven and preheat to 350 degrees. (325 for dark pans).
2. Bring a saucepan of water to a boil and turn off heat. Combine butter and chocolate in a heatproof bowl and set over pan of water. Stir occasionally until melted.
3. Whisk eggs together in a large bowl, then whisk in salt, sugars, and vanilla. Stir in chocolate and butter mixture, then fold in flour.
4. Pour batter into prepared pan and spread evenly. Bake for about 30 - 40 minutes,*** until top has formed a shiny crust and batter is moderately firm. Cool in pan on a rack. Wrap pan in plastic wrap and keep at room temperature or refrigerated until next day.
5. To cut brownies, unmold onto a cutting board, remove paper, and replace with another cutting board. Turn cake right side up and trim away edges. Cut brownies into 2-inch squares.
*** Note: The original said to bake 45 minutes, but many reviewers found it to be too long.
Serving: Serve the brownies on their own or with ice cream and hot fudge sauce.
Storage: The best way to store brownies is to wrap them individually and keep them at room temperature in a tin or plastic container with a tight-fitting cover. Or freeze them.
Note: If you have a 12 x 18-inch commercial half-sheet pan, you may double this recipe easily.
