Ingredients
2 and 1/4 cups (281g) all-purpose flour
1 teaspoon baking soda
1 and 1/2 teaspoons cornstarch
1/2 teaspoon salt
3/4 cup (170g) unsalted butter, melted and slightly cooled
3/4 cup (150g) packed light or dark brown sugar
1/2 cup (100g) granulated sugar
1 large egg + 1 egg yolk, at room temperature
2 teaspoons pure vanilla extract
1 and 1/4 cups (225g) semi-sweet chocolate chips or chunks
Instructions
- In a large bowl, whisk flour, baking soda, cornstarch, and salt. Set aside.
- In a medium bowl, whisk together melted butter, brown sugar, and granulated sugar until smooth. Whisk in the egg, egg yolk, and vanilla.
- Pour the wet ingredients into the dry and mix with a spatula until combined. Fold in the chocolate chips. The dough will be thick and shiny.
- Cover and chill dough for at least 2 hours or up to 3 days.
- Preheat oven to 325°F (163°C). Line baking sheets with parchment paper or silicone mats. Let dough sit at room temp for 15 minutes if too hard to scoop.
- Scoop 2 heaping tablespoons (about 1.75 oz or 50g) of dough per cookie and shape into tall mounds. Place 3 inches apart on baking sheets.
- Bake for 13–14 minutes or until edges are lightly browned. Centers will look soft. Let cool on the sheet for 10 minutes before transferring to a rack.
Notes
- Chilling the dough is crucial for thick, chewy cookies.
- Shape dough into tall, rough mounds for a bakery-style look.
- You can omit cornstarch, but cookies will be slightly less soft.
- Use room temp eggs for best consistency.
- Add-ins like nuts or candies can replace some or all chocolate chips—limit to 1 to 1¼ cups total.
- Dough can be frozen as balls for up to 3 months; bake from frozen with 1 extra minute.
