Ingredients
Method
- Preheat oven to 350F (175C) and lightly grease and flour sides and bottom of a 13×9 baking dish (or spray with baking spray). Set aside.
- COOKIE DOUGH: 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.
- 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.
- ASSEMBLY: 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!
