Preheat the oven to 350℉. Line a 9x9-inch pan with parchment paper, leaving the edges to hang over the sides of the pan or grease with non-stick cooking spray.
Whisk together the melted butter and sugar. Add the eggs and vanilla extract and whisk for 1 minute until smooth and frothy. Finally whisk in the flour, cocoa, baking powder, and salt just until no streaks of flour remain.
½ cup salted butter, 1 cup white sugar, 2 whole eggs, 1 teaspoon vanilla extract, ½ cup all-purpose flour, ¼ cup cocoa powder, ¼ teaspoon baking powder, ⅛ teaspoon salt
Stir together the peanut butter and powdered sugar until combined. Pour most of the brownie batter into the prepared pan, reserving about ½ cup of the batter. Spread the peanut butter/powdered sugar mixture on top of the batter in the pan. Drop spoonfuls of the reserved ½ cup of batter over the peanut butter and then run a butter knife through the batter to create swirls. Do not overmix while doing this!
½ cup creamy peanut butter, 2 tablespoons powdered sugar
Bake in the preheated oven for 25-25 minutes depending on how well done you like your brownies. Let cool for at least 10-15 minutes before serving. Enjoy!

Or use unsalted butter instead with an additional ¼ teaspoon of salt added to the recipe.
This recipe has only been tested with creamy-style peanut butter. I am not sure how it would turn out with natural-style peanut butter.
