Ingredients
Method
- Whisk the flour, baking soda, cornstarch, and salt together in a large bowl until evenly combined.
- In a separate bowl, stir together the melted butter, brown sugar, and granulated sugar until smooth and glossy.
- Beat in the egg and extra yolk until fully blended, then stir in the vanilla extract until the mixture looks uniform and silky.
- Pour the wet mixture into the bowl of dry ingredients and stir just until a thick, shiny dough forms with no dry patches.
- Gently fold in the chocolate chips, making sure they are spread throughout the dough.
- Cover the bowl tightly and refrigerate the dough for at least 2 hours so it can firm up and bake thicker.
- When ready to bake, set the oven to 325°F (163°C) and line baking sheets with parchment paper or silicone mats.
- If the dough is very firm, let it sit out for about 15 minutes, then scoop portions and roll them into tall, thick mounds rather than wide balls.
- Arrange the dough portions on the prepared baking sheets, leaving plenty of space between each one for spreading.
- Bake for 13–14 minutes, until the edges look lightly golden while the centers still appear soft and underbaked.
- Let the cookies rest on the hot pan for about 10 minutes before moving them to a rack to cool completely and finish setting.
