Brookies are a fun combination of chocolate chip cookie bars and brownies, all swirled together in one pan! They're loaded with chocolate chips and are perfectly chewy and fudgy. Recipe includes a how-to video.
Add dry ingredients to wet and stir until completely combined. Stir in chocolate chips. Set aside and prepare your Brownie batter.
1 cup semisweet chocolate chips
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.
¾ cup unsalted butter, ½ cup semisweet chocolate chips
Add cocoa powder and stir well.
½ cup natural cocoa powder
Stir in sugars.
½ cup sugar, 1 cup light brown sugar
Add eggs, egg yolk, vanilla extract, and salt and stir to combine.
2 large eggs + 1 egg yolk, 1 teaspoon vanilla extract, ½ teaspoon salt
Add flour and stir until well mixed. If desired, stir in mini chocolate chips.
1 cup all-purpose flour, ½ cup 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!

Notes
Butter
The butter should not feel too warm to the touch or it will melt your sugars.
Add-Ins
Feel free to substitute the chocolate chips for white chocolate chips, or add up to a heaping cup of your favorite nuts into the batter (I add a half cup into each batter before combining the two). Chopped walnuts work especially great here!
Storing
Store in an airtight container at room temperature for up to 5 days. Brookies may also be tightly wrapped and frozen for up to 3 months.
