Sebastian's Remarkably Wonderful Brownies
1 cup plus 2 tablespoons (150 grams) all-purpose flour
1 1/3 cups (113 grams) unsweetened Dutch-processed cocoa powder
1 stick plus 3 tablespoons (11 tablespoons; 5½ ounces; 156 grams) unsalted butter, cut into chunks, at room temperature
2½ cups (500 grams) sugar
½ teaspoon fine sea salt
1 teaspoon pure vanilla extract
4 large eggs, lightly beaten, at room temperature
Center rack in the oven and preheat it to 325 degrees. Butter the sides of a 9-x-13-inch baking pan, dust the interior with cocoa powder, tap out the excess and line the bottom with parchment paper.
Sift the flour and cocoa together.
Working with a stand mixer fitted with the paddle attachment, or in a large bowl with a hand mixer, beat the butter, sugar and salt together at low speed for 3 minutes, scraping the bowl as needed. Beat in the vanilla. If you're using a stand mixer, switch to the whisk attachment. With the mixer on medium-high pour in the eggs, then beat for about 5 minutes more or until the mixture has at least doubled in volume. Switch to a flexible spatula and gently fold in the dry ingredients, checking the bottom of the bowl frequently for dry ingredients. Don't be discouraged when your light batter collapses - it's unavoidable. Scrape the batter into the pan and smooth the top.
Bake for about 40 minutes, rotating the pan after 20 minutes, or until the brownies have puffed - the top may crack here and there - and a tester inserted into the center comes out clean. Transfer to a rack and allow the brownies to cool until they are slightly warm or at room temperature.
Run a table knife between the brownies and the sides of the pan, cut the brownies into quarters and carefully lift the quarters out of the pan with a broad spatula. Cut the brownies into 20 bars.
Wrapped well, the brownies will keep at room temperature for about 3 days. Packed airtight, they can be frozen for up to 2 months.
