Ingredients
Scale
- ¾ cup (170g) unsalted butter, softened
- ¾ cup (165g) packed light brown sugar
- ¼ cup + 2 tablespoons (60g) granulated sugar
- 1 large egg
- 1 large egg yolk
- 1 tablespoon (15ml) pure vanilla extract
- 1 ¾ cups + 2 tablespoons (254g) all-purpose flour
- ¾ teaspoon salt
- ¼ + 1/8 teaspoon baking soda
- 1 cup (180g) chocolate chips
- 6 ounces dark chocolate, melted
- ¾ cup (170g) unsalted butter, melted
- 1 ½ cups (285g) granulated sugar
- 3 large eggs
- 1 large egg yolk
- 1 tablespoon (15ml) pure vanilla extract
- ¾ cup (105g) all-purpose flour
- ¾ cup (84g) cocoa powder, sifted
- 1 teaspoon salt
- ¾ teaspoon baking powder
Instructions
- Preheat the oven to 350°F. Grease a 9×13-inch pan and line the bottom and sides with parchment paper. Allow the butter to soften for at least 20 minutes.
- Combine the softened butter with the brown and granulated sugar. Beat on medium speed until well combined, 2-3 minutes.
- Add the egg, egg yolk, and vanilla extract and continue beating until well incorporated.
- In a separate bowl, combine the flour, salt, and baking soda. Stir to combine and slowly add the dry ingredients into the dough, mixing on low speed until the dough starts to form. Before the dough thickens, add the chocolate chips. Beat until incorporated. Set aside.
- Chop the chocolate into smaller pieces and melt in a microwave-safe bowl for approximately 2 minutes at 50% power. Stir occasionally until completely melted and smooth. Set aside to cool.
- Melt the butter in a microwave-safe bowl and combine with the granulated sugar; beat together until well combined.
- Add the egg and egg yolk and beat for 60 seconds at a higher speed until the batter is fluffy.
- Add the vanilla extract and melted chocolate and beat until combined.
- Combine the dry ingredients in a separate bowl and stir to combine. Gradually add the dry ingredients to the batter and mix just until combined.
- Pour the brownie batter into the bottom of the pan. Take large pieces of the cookie dough, flatten them, and press them into the brownie batter. Continue layering the remaining cookie dough.
- Bake at 350°F for 35-40 minutes, covering with aluminum foil after 15-20 minutes to prevent too much browning. Test for doneness with a toothpick; the brownie should be a little fudgy but not wet.
Notes
- Ensure all ingredients are at room temperature for best results.
- Store any leftovers in an airtight container.
- For a nutty flavor, consider adding nuts to the brownie layer.
