Preheat the oven to 175°C (350°F). Line an 20 cm (8-inch) square baking pan with parchment paper, leaving an overhang for easy removal.
Cut the butter and dark chocolate into small pieces. Place them in a heatproof bowl and melt together over a saucepan of gently simmering water, ensuring the bowl does not touch the water. Stir until smooth, then remove from the heat.
Stir the brewed espresso and vanilla extract into the melted chocolate mixture. Set aside to cool slightly.
In a large bowl, whisk the sugar and eggs together for 2–3 minutes, until the mixture is smooth, slightly pale, and thickened.
Slowly pour the warm chocolate mixture into the egg mixture while whisking continuously. Mix until evenly combined.
Sift the flour, cocoa powder, and salt over the wet mixture. Fold gently with a spatula just until no dry streaks remain; do not overmix.
Transfer the batter to the prepared pan and spread it into an even layer.
Bake for 22–27 minutes, or until the edges are set and a toothpick inserted near the center comes out with moist crumbs rather than wet batter.
Let the brownies cool completely in the pan. Lift them out using the parchment-paper overhang, slice into squares, and serve.
