Scale
- 10 tablespoons of unsalted butter
- 1 1/4 cups of granulated sugar
- 3/4 cup plus 2 tablespoons of unsweetened cocoa powder, natural or Dutch-process
- 1/4 rounded teaspoon of kosher salt (use slightly less if using fine sea or table salt)
- 1 teaspoon of vanilla extract
- 2 large cold eggs
- 1/2 cup of all-purpose flour
- 2/3 cup of chopped walnuts or pecans, optional
Instructions
- Preheat your oven to 325 degrees F with an oven rack in its center. Using aluminum foil or parchment paper, line the bottom and edges of an 8-inch × 8-inch square baking pan. Leave an overhang on opposite sides of the pan to help remove the brownies from the pan after they’re done baking.
- Pour water into a medium saucepan, about 2 inches deep in the pan to make a double-boiler. Bring the water to a gentle simmer.
- In a medium-sized heat-safe bowl, mix the butter, cocoa powder, sugar, and salt. Place the bowl over a pot of boiling water. Take a bit of the water out of the saucepan if you find that the bowl’s bottom is reaching the water.
- Toss the mixture from time to time until the butter melts completely, and gets to a comfortable temperature. Don’t worry if the butter appears gritty at first; as soon as the eggs and flour are introduced into the mix, it will smoothen out.
- Take the bowl out of the saucepan and set it aside for 5 minutes, or until warm but not hot.
- Mix in the vanilla extract.
- Add the eggs one at a time, making sure to stir the mixture vigorously after each addition.
- Add the flour when the batter appears thick and well combined. Mix in the flour with a spoon until the mixture is really thick and pulls off the sides of the mixing basin. You should beat the mixture with a spatula or wooden spoon for 40 to 50 strokes.
- If using, stir in the nuts at this point.
- In the prepared pan, spread the batter evenly.
- Bake the brownies for 20 to 30 minutes, or until the edges are dry and the middle is slightly underbaked. You can test if the brownies are done by pushing a toothpick into its center. You should know that the brownies are finished baking if they come out with some attached moist crumbs.
- Allow the brownies to cool completely before you take them out of the pan – this step is crucial if the brownies are to solidify properly. Afterwards, cut the cake into 16 square brownie pieces.
Notes
- Glass and ceramic baking pans work, however bear in mind that the bake time may be affected if you decide to use this cookware. Check for doneness 5 minutes before you serve the brownies and every 5 minutes thereafter.
- Microwave cooking: This recipe can also be made in a microwave. In a microwave-safe bowl, combine the butter, sugar, cocoa powder, and salt, and microwave the brownie mixture in 20-second increments until the butter is melted into the sugar. Make sure to whisk the mixture after each microwave cycle.
- Instead of a double-boiler, use a saucepan: The double-boiler protects the batter from burning, but you can instead use a medium saucepan to incorporate the butter, cocoa powder, sugar and salt. Place the pot over a low heat setting. Stir until the butter has melted into the sugar.
