Preheat your oven to 325 degrees Fahrenheit (165 degrees Celsius). Line a 9x9-inch baking pan with parchment paper and lightly coat it with cooking spray. Set aside.
Prepare the boxed brownie mix according to the package instructions, incorporating the specified quantities of eggs, oil, and water. Mix until well combined, then set aside.
For the peanut butter dough: In a large bowl, whisk together the melted butter, granulated sugar, and packed brown sugar until well combined.
Add the creamy peanut butter to the sugar mixture and vigorously whisk for about 30-45 seconds until the mixture is smooth and well incorporated.
Incorporate the egg and egg yolk, whisking for an additional 30 seconds after each addition. This part is important, this is what gets the shine on top.
Mix in the pure vanilla extract until fully combined.
Switch to a rubber spatula and gently fold in the all-purpose flour, baking powder, and salt. Be careful not to overmix; just mix until the ingredients are combined.
Stir in the dark chocolate chips to the peanut butter cookie dough.
To assemble the brookies, use two spoons to alternate between spoonfuls of brownie batter and peanut butter cookie dough, creating a marbled effect in the prepared baking pan. Remember, the smaller the dollops the better it looks!
Bake in the preheated oven for 50-55 minutes. Begin checking for doneness around 45 minutes by inserting a toothpick into the center. It should come out with a few moist crumbs attached.
Once baked, remove the pan from the oven and let the peanut butter brookies cool in the pan before slicing and serving.
To add Swirls of peanut butter, I melted a coupe tablespoons and poured it on top right after the brookies came out!
