Preparation Method
- Preheat the oven to 350°F (180°C) with a rack set in the middle position. Lightly spray a 13-by-9-inch (33-by-23-centimeter) baking pan with cooking spray and line with parchment paper, extending the edges outside the pan.
- In a medium bowl, stir together flour and cocoa powder. Set aside.
- In a double boiler over medium heat, heat butter and chocolate until melted, stirring occasionally.
- In the mixing bowl of the stand mixer fitted with the flat beater attachment and the splash guard installed, add sugars, eggs, vanilla extract, and salt. Beat on medium (5–6) speed for 1 minute. Add the chocolate mixture. Continue beating until blended, about 1 minute.
- Reduce the mixer speed to low (1–2) and add the flour mixture. Slowly increase the mixer speed to medium (5–6) and beat until blended.
- Pour the batter into the prepared pan and spread evenly. Bake until the top is shiny and a cake tester comes out with a few crumbs attached, 50–55 minutes. Let the brownies cool in the pan on a wire rack.
- Using the edges of the parchment paper, lift the brownies out of the pan and place on a cutting board. Cut into wedges or squares to serve.
Pro Tip
The flavor continues to develop throughout the second day. Try enjoying half of the pan fresh and freezing the other half to enjoy at a later date.
