Step-by-Step Instructions
For the Brownie Layer:
- Preheat and Prep: Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy lifting. This will help you remove the brownies cleanly after baking.
- Melt Butter and Cocoa: In a medium microwave-safe bowl, melt your 1 cup of unsalted butter. Whisk in the 1/2 cup unsweetened cocoa powder until smooth.
- Add Sugars and Eggs: To the melted butter and cocoa mixture, add the 1 cup granulated sugar and 1 cup packed light brown sugar. Stir until well combined. Add the 2 large eggs, one at a time, whisking well after each addition until the mixture is glossy. Stir in the 1 teaspoon of vanilla extract.
- Incorporate Dry Ingredients: In a separate small bowl, whisk together the 1 cup all-purpose flour, 1 teaspoon baking soda, and 1/2 teaspoon salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
- Add Chocolate Chips (Brownie Layer): Fold in 1 cup of semi-sweet chocolate chips into the brownie batter.
For the Chocolate Chip Cookie Dough Layer:
- Cream Butter and Sugars: In a separate medium bowl, combine the 1/2 cup melted unsalted butter with 1/4 cup packed light brown sugar and 1/4 cup granulated sugar. Stir until well combined.
- Add Egg and Vanilla: Beat in the 1 large egg and 1 teaspoon vanilla extract until the mixture is smooth and creamy.
- Incorporate Dry Ingredients for Cookie Dough: In another small bowl, whisk together the 3/4 cup all-purpose flour, 1/4 teaspoon baking soda, and a pinch of salt. Add these dry ingredients to the wet ingredients for the cookie dough, mixing until just combined.
- Add Chocolate Chips (Cookie Dough Layer): Fold in the remaining 1/2 cup of semi-sweet chocolate chips.
Assembling and Baking The Best Chocolate Chip Brownie Swirl Cookies:
- Layer the Brownie Batter: Spread the prepared brownie batter evenly into the bottom of the prepared baking pan. You want a consistent layer.
- Dollop the Cookie Dough: Randomly drop spoonfuls of the chocolate chip cookie dough over the top of the brownie batter. Don't worry about covering it completely; the swirling will take care of distribution.
- Swirl the Layers: Using a knife or a skewer, gently swirl the cookie dough into the brownie batter. Create marbled patterns for that signature swirls look. Don't over-swirl, or the layers will blend too much.
- Bake: Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached (not wet batter). The edges should be set.
- Cool and Cut: Let the brownie swirl cookies cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang. Once cooled, cut into squares.
