Method
- In a medium bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt. Set aside.
- In a large bowl with a stand mixer or hand mixer, beat the cold, cubed butter, packed brown sugar, and granulated sugar on medium speed for 2-3 minutes until light and fluffy.
- Add the egg, egg yolk, and vanilla extract. Beat until just combined. Scrape down the sides of the bowl as needed.
- On low speed, gradually add the flour mixture to the butter mixture. Mix only until a dough forms. Do not overmix. Gently fold in the milk chocolate chips.
- Cover the dough and chill in the refrigerator for at least 4-6 hours, or overnight for best results. This is a critical step for thick cookies.
- Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper. Use a large scoop (about 1/2 cup) to create large dough balls. Place them 3-4 inches apart on the baking sheet.
- Bake for 10-12 minutes. The edges should be set and lightly golden, but the centers will look soft and slightly underdone.
- Let the cookies cool on the baking sheet for 10 minutes before transferring them to a wire rack to cool completely. This helps them set.

Notes
For the most authentic taste, use high-quality, large milk chocolate chips.
Chilling the dough is mandatory for this recipe to prevent the cookies from spreading too thin.
The cookies will appear underdone in the center when you pull them from the oven. This is key to achieving the gooey Crumbl texture.
