These brownies combine the rich flavors of chocolate and peanut butter in a delightful swirl pattern, creating a treat that's both visually appealing and delicious.
Preheat your oven to 350°F (175°C).
Preheating ensures even baking from the start.
Grease and flour an 8-inch square baking pan.
Use parchment paper for easier removal of the brownies.
In a mixing bowl, cream together the butter and peanut butter using an electric mixer until smooth.
Ensure the butter is at room temperature for easier mixing.
Add the brown sugar and beat until well combined.
Scrape down the sides of the bowl to ensure even mixing.
Beat in the eggs, one at a time, followed by the vanilla extract.
Mix just until combined to avoid overmixing.
In another bowl, sift together the flour, salt, and baking powder.
Sifting helps to aerate the flour and remove lumps.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Do not overmix to keep the batter light.
Fold in the chocolate chips using a spatula.
Reserve a few chocolate chips to sprinkle on top for presentation.
Pour the batter into the prepared pan and spread it evenly.
Tap the pan gently on the counter to remove air bubbles.
Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Check the brownies early to avoid overbaking.
Allow the brownies to cool completely in the pan before cutting into squares.
Use a sharp knife for clean cuts and wipe it between slices.
