Ingredients

  • 10 tablespoons (145 g) unsalted butter
  • 1¼ cups (250 g) granulated sugar
  • ¾ cup plus 2 tablespoons (75 g) unsweetened cocoa powder, spooned and leveled
  • 1 teaspoon vanilla extract
  • ¼ teaspoon fine sea salt
  • 2 large cold eggs
  • ½ cup (65 g) all-purpose flour, spooned and leveled
  • ⅔ cup (80 g) chopped walnuts, pecans, or chocolate chips, optional

Instructions

  1. Heat the oven to 325°F with a rack in the middle. Line an 8-inch square pan with parchment or foil, leaving an overhang.
  2. Melt the butter in a medium saucepan over medium-low. Turn off the heat. While it is still hot, stir in the sugar, cocoa, vanilla, and salt. It will look gritty. Cool 5–10 minutes until warm, not hot.
  3. Beat in the cold eggs one at a time, stirring hard after each.
  4. Add the flour and beat until the batter is very thick and pulls away from the pan. Stir in nuts or chips if using.
  5. Spread in the pan (it is stiff). Bake 20–30 minutes, until the edges look set and the center is slightly underbaked. A toothpick should come out with moist batter.
  6. Cool completely in the pan before lifting out and cutting. They firm up as they cool.
