The brownies will appear undercooked if cut into before completely cool.
2 sticks (1 cup) unsalted butter
8 ounces bittersweet (60 percent cacao) chocolate, coarsely chopped, such as Ghiradelli  or Callebaut 
1 1/4 cups (6 1/2 ounces) all-purpose flour
1 teaspoon baking powder
1 1/2 tablespoons cocoa powder
3/4 teaspoon kosher salt
2 cups (14 ounces) granulated sugar
4 large eggs, at room temperature
2 teaspoons vanilla extract
Fleur de sel
- Put oven rack in middle position, and preheat oven to 350°F. Grease an 8-inch square baking pan with butter; line pan with parchment paper, leaving a 2-inch overhang on two sides.
- Melt butter and chocolate in a medium heatproof mixing bowl set over a saucepan of simmering water, stirring occasionally, until smooth.
- Whisk together flour, baking powder, cocoa powder, and salt in a small mixing bowl.
- Whisk together sugar, eggs, and vanilla in a large bowl, then pour in chocolate mixture, whisking until combined well. Whisk in flour mixture, and transfer batter to baking pan. Smooth out the batter with an offset spatula, and generously sprinkle the surface with fleur de sel.
- Bake until the top is shiny, the sides have begun to pull away slightly from the pan, and the center has puffed up but is still slightly jiggly (a wooden pick or skewer will not come out clean), about 45 to 50 minutes.
- Cool brownies completely in the pan on a wire rack. Gently transfer the brownies from the pan to a cutting board using the parchment sling, and remove paper. The edges will be quite crisp; for fudgy brownies through and through (and a neater appearance) trim away the edges before cutting into squares. Discard the trimmings, or share them with a friend who prefers crisp, chewy brownies.
