Method
- Heat the oven to 350°F.
- Line two 18x13-inch rimmed baking sheets with parchment paper.
- In a large bowl, beat the softened unsalted butter and packed light brown sugar with a mixer on medium speed for 2 minutes, until smooth and fluffy.
- Beat in the egg and egg yolk until combined.
- Mix in the vanilla extract.
- In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.
- Add the flour mixture to the butter mixture and mix on low just until no dry streaks remain.
- Cover the dough and refrigerate for 30 to 45 minutes.
- Scoop the dough into 1 1/2-tablespoon portions.
- Arrange 12 portions on each prepared baking sheet, spacing them about 2 inches apart.
- Bake for 10 to 12 minutes, until the edges are set and lightly browned and the centers still look slightly soft.
- Let the cookies cool on the baking sheets for 5 minutes.
- Transfer the cookies to a wire rack to cool completely.
Notes
For chewy centers, take the cookies out when the edges are set and lightly browned while the centers still look slightly soft. Store in an airtight container in the refrigerator for up to 5 days; freezer-friendly. For a dairy-free variation, use a plant-based butter substitute.
