Preheat your oven to 180°C (350°F) and line an 8-inch square baking pan with parchment paper.
In a heatproof bowl, melt the dark chocolate and unsalted butter together over a pot of simmering water, stirring until smooth. Remove from heat and let it cool slightly.
In a separate bowl, whisk together the granulated sugar and eggs until the mixture is pale and slightly thickened.
Stir in the melted chocolate mixture and vanilla extract into the sugar and egg mixture until well combined.
Sift in the all-purpose flour and salt, and gently fold the mixture until just combined.
Pour the brownie batter into the prepared baking pan, spreading it evenly.
Drop spoonfuls of peanut butter over the top of the brownie batter and use a knife to swirl it into the batter.
Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Allow the brownies to cool in the pan before cutting them into squares and serving.
