directions

Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper or lightly grease it.

In a saucepan, melt the butter over low heat. Remove from heat and stir in granulated sugar, salt, eggs, and vanilla extract.

Sift in cocoa powder and flour, mixing until just combined. Fold in chocolate chips.

Pour the brownie batter into the prepared pan and spread evenly.

In a separate bowl, mix the peanut butter with powdered sugar until smooth and thick.

Drop spoonfuls of the peanut butter mixture onto the brownie batter. Use a knife to swirl it gently into the top of the batter.

Bake for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Let the brownies cool completely in the pan before cutting into squares.
