Chocolate Chip Brownie Swirled Cookies (Brookies!)

Ingredients

For the Chocolate Chip Cookie:
• 1 and 1/4 cups all-purpose flour
• 1/2 teaspoon baking soda
• 1/4 teaspoon flaky sea salt (regular salt also works just fine)
• 7 tablespoons unsalted butter, at room temperature
• 1/2 cup packed dark brown sugar
• 1/4 cup granulated sugar
• 1 teaspoon vanilla
• 1 large egg
• 3/4 cup semi-sweet chocolate chips
For the Brownie Cookie:
• 6 tablespoons unsalted butter, melted
• 1/2 cup semi-sweet chocolate chips, melted
• 1 cup all-purpose flour
• 2 tablespoons unsweetened cocoa powder
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1/2 cup packed dark brown sugar
• 1/4 cup granulated sugar
• 1 teaspoon pure vanilla extract
• 1 large egg + 1 egg yolk, at room temperature
• 3/4 cup semi-sweet chocolate chips

Directions

1. Make the chocolate chip cookie dough first — it needs to chill for a bit while you make the brownie cookie dough.
For the Chocolate Chip Cookie Dough:
2. In a medium bowl, whisk together the flour, baking soda, and sea salt.
3. In a large bowl, add the butter and both sugars, and beat with an electric handheld mixer or paddle attachment until light and fluffy, about 2 minutes. Add the vanilla and egg, and continue mixing until well incorporated.
4. Add the dry ingredients, and beat on low speed just until combined — be careful not to overmix! Fold in the chocolate chips, and then cover and refrigerate the dough for at least 45 minutes. You can make the brownie dough while you’re waiting!
For the Brownie Cookie Dough:
5. Place the butter and chocolate in a small sauce pan over low-medium heat, and cook for about 2 minutes, or until the butter and chocolate are completely melted. Remove from heat and whisk until completely smooth.
6. In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt.
7. Add the sugars and the vanilla to the chocolate mixture and whisk until well combined (this works best with a hand mixer or stand mixer). Add in the egg and egg yolk, and beat well to combine.
8. Gently fold in the dry ingredients into the chocolate mixture with a rubber spatula, stirring just until combined. Fold in chocolate chips.
Assembly and Baking:
9. Preheat oven to 350 degrees F, and line 2 large baking sheets with parchment paper or silicone baking mats.
10. Place a piece of parchment on your counter or another flat surface. Using a small ice cream scoop or tablespoon, portion your chocolate chip cookie dough into tablespoon-sized rounds, and rest them on your parchment-covered workspace. Repeat the same with the brownie cookie dough.
11. When ready to combine, gentle push together one scoop of chocolate chip cookie dough and one scoop of brownie cookie dough, and gently pinch the seams together. Place two inches apart on your prepared baking sheets, and bake in your preheated over for about 12 minutes. The edges and tops should be set, but the centers may look slightly underdone.
12. Let the cookies cool for about 10 minutes on the baking sheets before transferring them to a wire rack to finish cooling completely.
