These classic American fudgy brownies deliver a crackly paper-thin top and an impossibly dense, moist center thanks to a high butter-to-flour ratio and melted dark chocolate. The simple one-bowl method produces bakery-quality squares every time, perfect for bake sales and weeknight treats alike.

Ingredients
For the brownie batter
- 170 g (6 oz) dark chocolate (60-70% cacao), chopped
- 113 g (1/2 cup) unsalted butter, cubed
- 300 g (1 1/2 cups) granulated sugar
- 2 large eggs, room temperature
- 1 large egg yolk, room temperature
- 2 teaspoons pure vanilla extract
- 60 g (1/2 cup) all-purpose flour
- 30 g (1/4 cup) unsweetened Dutch-process cocoa powder
- 1/2 teaspoon fine sea salt
Optional finishing
- Flaky sea salt, for sprinkling
- 1 teaspoon instant espresso powder (boosts chocolate flavor)
Directions
- Preheat the oven to 175°C (350°F). Line an 8×8-inch (20×20 cm) square metal baking pan with parchment paper, leaving overhang on two sides for easy lifting, then lightly grease the exposed pan.
- Combine the chopped chocolate and butter in a heatproof bowl set over a saucepan of barely simmering water (or microwave in 20-second bursts), stirring until completely smooth. Remove from heat and whisk in the granulated sugar until glossy and slightly cooled, about 1 minute.
- Whisk in the eggs, egg yolk, and vanilla one at a time, beating vigorously for about 30 seconds after each addition until the batter looks thick, shiny, and ribboned.
- Sift the flour, cocoa powder, espresso powder (if using), and salt directly over the chocolate mixture. Fold gently with a rubber spatula until just combined and no dry streaks remain; do not overmix.
- Pour the thick batter into the prepared pan and smooth the top with an offset spatula. Tap the pan firmly on the counter 3 times to release any air bubbles.
- Bake on the center rack for 28-32 minutes, until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs attached (not wet batter). The top should look crackly and matte.
- Transfer the pan to a wire rack and let cool completely in the pan, about 2 hours. Sprinkle with flaky sea salt if desired, then lift out using the parchment and slice into 9 squares with a sharp knife wiped clean between cuts.
Cook’s Notes
- Do not overbake; pull the brownies when a toothpick still shows moist crumbs for that signature fudgy pull-apart texture.
- Use good-quality chocolate bars rather than chocolate chips, which contain stabilizers that prevent smooth melting.
- Bring eggs to room temperature so they emulsify properly into the warm chocolate without seizing or scrambling.
- For ultra-clean cuts, chill the cooled brownies in the fridge for 30 minutes, then slice with a knife dipped in hot water and dried between cuts.
- Stir in 3/4 cup toasted walnuts or pecans, or swirl in 1/4 cup peanut butter or Nutella before baking for variation.
