Ingredients
  

  • 1/2 cup (115 g) unsalted butter
  • 3/4 cup (150 g) granulated sugar
  • 1/4 cup (50 g) light brown sugar, packed
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon fine sea salt
  • 1/3 cup (35 g) black cocoa powder
  • 1/4 cup (25 g) natural or Dutch-processed cocoa powder
  • 1/2 cup (64 g) all-purpose flour, spooned and leveled
  • 1/2 teaspoon instant espresso powder (optional, enhances chocolate)
  • 1/2 cup (85 g) dark chocolate chips or chopped dark chocolate (optional, for extra richness)

Instructions
 

  • Prep the pan: Heat oven to 350°F (175°C). Line an 8-inch square pan with parchment, leaving overhang for easy lifting. Lightly grease the parchment.
  • Melt the butter with sugar: In a medium saucepan over low heat, melt the butter. Stir in granulated and brown sugars. Warm for 1–2 minutes, stirring, until the mixture looks glossy and a bit fluid—not boiling. This step helps that crackly top.
  • Cool slightly, then add eggs: Remove from heat. Let sit 1–2 minutes so it’s warm, not hot. Whisk in the eggs one at a time until fully combined and slightly thickened. Mix in vanilla and salt.
  • Add cocoa powders and espresso: Sift in black cocoa, regular cocoa, and espresso powder. Whisk until smooth and dark. The batter will look shiny and thick.
  • Fold in flour: Use a spatula to fold in the flour just until no dry streaks remain. Do not overmix. If using chocolate chips, fold them in now.
  • Pan and smooth: Scrape batter into the prepared pan and smooth the top. Tap the pan once on the counter to pop air bubbles.
  • Bake: Bake 18–24 minutes, depending on your oven. You want set edges and a center that’s slightly soft. A toothpick should come out with moist crumbs, not wet batter.
  • Cool and slice: Cool in the pan on a rack for at least 1 hour. For the cleanest slices and maximum fudginess, chill 30 minutes before cutting into squares.
