Ingredients: 1 cup unsalted cold butter (cut into small cubes); 1 cup packed light brown sugar; ½ cup graulated white sugar; 2 large eggs; ½ cup dark unsweetened cocoa powder (use a premium brand for richer flavor; do not use dutch processed); 1 cup cake flour; 1½ cup all-purpose flour; 1 teaspoon cornstarch; ¾ teaspoon baking soda; ½ teaspoon salt; 1 1/3 cups semisweet chocolate chips; 3/4 cup Nutella (it's best if you use a fresh new jar of Nutella as the spread will be very moist and easy to scoop)
