# What You'll Need:
→ Brownie Base
01 - 1/2 cup unsalted butter, melted
02 - 1 cup granulated sugar
03 - 2 large eggs
04 - 1 teaspoon vanilla extract
05 - 1/3 cup unsweetened cocoa powder
06 - 1/2 cup all-purpose flour
07 - 1/4 teaspoon salt
08 - 1/4 teaspoon baking powder
→ Swirl
09 - 1/2 cup creamy peanut butter
# Steps to Follow:
01 - Preheat the oven to 350°F (175°C) and grease a square baking pan.
02 - In a large bowl, whisk together melted unsalted butter, granulated sugar, eggs, and vanilla extract until smooth.
03 - Stir in cocoa powder, all-purpose flour, salt, and baking powder until just combined; do not overmix.
04 - Pour half of the batter into the prepared pan. Drop spoonfuls of creamy peanut butter over the batter, then spread the remaining batter on top. Use a knife to gently swirl the peanut butter through the batter to create a marbled effect.
05 - Bake for 25–30 minutes or until the brownies are set and a toothpick inserted in the center comes out with a few moist crumbs.
06 - Allow brownies to cool in the pan before slicing and serving.
