Chocolate Peanut Butter Brownies

Preheat the oven to 350°F (175°C).

Line an 8x8 inch baking pan with parchment paper.

Melt the butter in a saucepan or microwave and let it cool slightly.

Whisk in sugar, eggs, and vanilla until smooth.

Stir in flour, cocoa powder, and salt until combined.

Fold in the chocolate chips.

Pour batter into the prepared pan and smooth the top.

Spoon peanut butter on top and swirl with a knife.

Bake for 25–30 minutes, until set in the center.

Cool before slicing into squares.
