Brownie batter and cookie dough are swirled together to create these soft and chewy brookies. If you can't decide whether to make fudgy brownies or chewy chocolate chip cookies, now you can make both!
Preheat the oven to 350°F (177°C). Line a 9x13 inch baking pan with foil or parchment paper, making sure to leave some overhang for easy removal. Spray the foil/parchment paper well with nonstick cooking spray and set aside.
To make the brownie batter: In a large mixing bowl, whisk together the melted butter and sugar until well combined, then whisk in the eggs and vanilla extract.
Sift in the flour, cocoa powder, and salt and continue whisking until just combined, stopping to scrape down the sides of the bowl as needed.
Set aside while you prepare the cookie dough.
To make the cookie dough: In a large mixing bowl, whisk together the melted butter and brown sugar until fully combined, then whisk in the egg and vanilla extract until just combined.
Add the flour, baking soda, and salt and mix until just combined, then fold in the semi-sweet chocolate chips.
To assemble the bars: Alternate dropping large spoonfuls of the brownie batter and cookie dough into the prepared pan. Use a knife to carefully swirl the batters together.
Bake for 25 to 30 minutes or until a toothpick inserted into the center comes out clean.
Remove from the oven and allow to cool completely on a wire rack. Once the bars have cooled, lift them out of the pan, slice, and enjoy.
