Ingredients
- 2 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup (2 sticks) unsalted butter, softened
- 3/4 cup granulated sugar
- 3/4 cup packed brown sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 cups semi-sweet chocolate chips
- 1 cup chopped walnuts or pecans (optional)
- 8 ounces high-quality dark chocolate, chopped
- 1/2 cup unsalted butter
- 3/4 cup granulated sugar
- 1/4 cup brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 2/3 cup all-purpose flour
- 1/4 cup unsweetened cocoa powder
- 1/4 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup semi-sweet chocolate chips
- Fleur de sel or sea salt for topping (optional)
Instructions
- Preheat your oven to 350°F. Line a 9×13-inch baking pan with parchment paper, leaving overhang on two sides for easy removal. This step is crucial for getting those perfectly clean edges.
- For the cookie layer, whisk together 2 cups flour, 1/2 teaspoon baking soda, and 1/2 teaspoon salt in a medium bowl. Set aside.
- In a large bowl, cream together 1 cup softened butter, 3/4 cup granulated sugar, and 3/4 cup brown sugar until light and fluffy, about 3-4 minutes. This creates the foundation for tender cookies.
- Beat in 2 eggs one at a time, then add 2 teaspoons vanilla extract. Mix until well combined and the mixture is pale.
- Gradually add the flour mixture to the wet ingredients, stirring until just combined. Don’t overmix—you want tender cookies, not tough ones.
- Fold in 2 cups chocolate chips and 1 cup nuts if using. The mixture should be thick and cookie-dough-like.
- Press the cookie dough firmly into the prepared baking pan, creating an even layer across the entire bottom. Use your hands or an offset spatula to smooth it out.
- Bake the cookie layer for 10-12 minutes, until it’s set but still slightly underbaked. The cookies should be golden brown but still have some give in the center.
- While the cookies bake, prepare the brownie layer. Melt 8 ounces chopped dark chocolate with 1/2 cup butter in a heatproof bowl over simmering water, stirring frequently until smooth. Alternatively, use a microwave in 30-second intervals.
- Remove the chocolate mixture from heat and let it cool for 2 minutes.
- In a bowl, whisk together 3/4 cup granulated sugar, 1/4 cup brown sugar, 2 eggs, and 1 teaspoon vanilla extract until well combined.
- Add the cooled chocolate mixture to the egg mixture and stir until smooth and well incorporated.
- In a separate bowl, whisk together 2/3 cup flour, 1/4 cup cocoa powder, 1/4 teaspoon baking powder, and 1/4 teaspoon salt.
- Fold the dry ingredients into the chocolate mixture until just combined. Don’t overmix—slight lumps are fine.
- Stir in 1/2 cup semi-sweet chocolate chips for extra fudgy texture and chocolate flavor.
- Remove the partially baked cookie layer from the oven and let it cool for 2 minutes.
- Carefully pour and spread the brownie batter over the warm cookie layer, using an offset spatula or the back of a spoon to create an even layer.
- Bake for 22-25 minutes, until a toothpick inserted into the brownie layer comes out with just a few moist crumbs. The brownie layer should look slightly underbaked for maximum fudginess.
- Remove from the oven and immediately sprinkle with fleur de sel if desired. This enhances the chocolate flavor beautifully.
- Allow to cool in the pan for at least 20 minutes before lifting out using the parchment overhang.
- Transfer to a cutting board and cut into squares. For cleaner cuts, wipe your knife between each cut and run it under hot water.
- Serve at room temperature or slightly warm. Store in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months.
Pro Tips
- This brownie and cookie recipe uses a combination of dark and semi-sweet chocolate for complex flavor. If you prefer milk chocolate, you can substitute, but the result will be sweeter and less sophisticated.
- The key to perfect brownie and cookie texture is not overbaking. Remember that these treats continue to cook slightly after removal from the oven due to residual heat. They’ll firm up as they cool.
- For the cookie layer, make sure your butter is truly softened to room temperature. Cold butter won’t cream properly and will result in dense cookies.
- Feel free to customize this brownie and cookie recipe with different mix-ins. Try adding espresso powder to the brownie layer for enhanced chocolate flavor, or use white chocolate chips in the cookie layer for contrast.
- If you don’t have a 9×13-inch pan, an 8×8-inch square pan works beautifully—just expect slightly thicker pieces and add 2-3 minutes to the baking time.
- For the neatest presentation when cutting your brownie and cookie creation, chill it completely first. Cold brownies cut much more cleanly than room temperature ones.
- This recipe is easily doubled if you want to make a 9×13 pan for a party. Simply double all ingredients and bake in two pans simultaneously.
- Store-bought chocolate works fine, but splurging on quality chocolate—like Ghirardelli or Lindt—makes a noticeable difference in the final result of your brownie and cookie recipe.
- These treats freeze beautifully for up to three months. Wrap individual pieces in plastic wrap and then place in a freezer bag. Thaw at room temperature for about 30 minutes before serving.
