Preheat oven to 350F (175C) and lightly grease and flour sides and bottom of a 13x9 baking dish (or spray with baking spray). Set aside.
Combine melted, cooled butter and sugars in a large bowl and stir well. Add egg, egg yolk, and vanilla extract and stir again to combine. Set aside.
In a separate bowl, whisk together flour, cornstarch, baking powder, and salt.
Add dry ingredients to wet and stir until completely combined. Stir in chocolate chips. Set aside and prepare your Brownie batter.
Combine butter pieces and ½ cup chocolate chips in a large heat-proof bowl. Transfer to microwave and heat in 20-second intervals, stirring very well in between until chocolate and butter are completely melted and mixture is smooth.
Add cocoa powder and stir well.
Stir in sugars.
Add eggs, egg yolk, vanilla extract, and salt and stir to combine.
Add flour and stir until well mixed. If desired, stir in mini chocolate chips.
Alternate dolloping large spoonfuls of cookie dough and brownie batter into baking dish. Use a knife to swirl through both doughs and make sure the batter is in an even layer.
Transfer to 350F (175C) oven and bake for 35-40 minutes or until a toothpick inserted in the center comes out with a few moist crumbs or clean (make sure you're not sticking the toothpick into a chocolate chip!). Take care to not over-bake your brookies or they will be dry and crumbly once cooled.
Allow to cool and slice and serve. Enjoy!
¹The butter should not feel too warm to the touch or it will melt your sugars.
