Ingredients
- 1 cup (2 sticks / 227 g) unsalted butter, melted
- 1 cup (200 g) light brown sugar, packed
- ½ cup (100 g) granulated sugar
- 2 large eggs, room temperature
- 1 large egg yolk, room temperature
- 2 teaspoons vanilla extract
- ½ cup (50 g) Dutch-process cocoa powder
- 2 ¼ cups (281 g) all-purpose flour
- 1 tablespoon cornstarch
- 1 teaspoon baking soda
- 1 teaspoon kosher salt
- 2 ½ cups (455 g) dark chocolate chips and chunks, divided (2 cups for the dough, ½ cup for topping)
Instructions
- Preheat oven to 350°F. Line a 15x10x1-inch sheet pan with parchment paper, leaving an overhang on the sides for easy removal.
- In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth and combined.
- Add the eggs, egg yolk, and vanilla extract. Whisk until smooth and fully combined.
- In a separate bowl, whisk together the cocoa powder, flour, cornstarch, baking soda, and kosher salt.
- Gradually add the dry ingredients to the wet ingredients, stirring just until combined. Do not overmix.
- Fold in 2 cups of the chocolate chips and chunks.
- Press the dough evenly into the prepared sheet pan, spreading it all the way to the edges. Sprinkle the remaining ½ cup chocolate chips and chunks evenly over the top, gently pressing them into the dough.
- Bake for 18 to 22 minutes, or until the edges are set and the center still looks slightly underbaked. The cookies will continue to set as they cool.
- Let the cookies cool completely in the pan before cutting into squares and serving.
