directions

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving overhang for easy lifting.

In a saucepan over medium heat, melt the butter. Remove from heat and stir in sugar, brown sugar, and cocoa powder until well combined.

Whisk in eggs one at a time, followed by vanilla extract.

In a separate bowl, whisk together flour, salt, and baking powder.

Gradually fold the dry ingredients into the wet mixture until just combined.

Stir in chocolate chips if using.

Pour the batter into the prepared pan and smooth the top.

Drop spoonfuls of peanut butter over the surface and use a knife to swirl it into the batter.

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

Cool completely in the pan before slicing into squares.
