Preheat your oven to 350°F (175°C) and prepare a baking sheet by lining it with parchment paper, ensuring easy removal of cookies later.
In a large mixing bowl, use an electric mixer to cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy, about 2-3 minutes.
Add the eggs to the mixture one by one, beating well after each addition to ensure they are fully incorporated. Pour in the vanilla extract and mix until combined.
In a separate medium bowl, whisk together the all-purpose flour, dark cocoa powder, baking soda, and fine sea salt until evenly blended. Gradually incorporate the dry mixture into the wet ingredients, mixing gently until just combined to prevent overworking the dough.
Carefully fold in the dark chocolate chips and crushed candy canes using a spatula or wooden spoon, ensuring they are evenly distributed throughout the dough.
Using a tablespoon or a cookie scoop, portion out the cookie dough and roll each portion into a smooth ball. Place the dough balls on the prepared baking sheet, spacing them about 2 inches apart to allow for spreading during baking.
Lightly flatten each cookie ball with the palm of your hand or the bottom of a glass. This will give you a thicker, chewy cookie that still retains its shape while baking.
Bake in the preheated oven for 10-12 minutes, or until the edges are firm but the centers remain soft and slightly underbaked for that chewy texture.
Allow the cookies to cool on the baking sheet for 5 minutes, then gently transfer them to a wire rack to cool completely, ensuring they maintain their soft center.
If desired, dust the cooled cookies with powdered sugar for a festive appearance before serving, adding a delightful touch of sweetness.
Notes
Arrange the cookies on a festive plate, and consider pairing them with a warm cup of hot cocoa for an extra cozy experience!
