Method
- In a large bowl, beat the butter, brown sugar, and granulated sugar with an electric mixer on medium speed for about 2 minutes, until creamy.
- Beat in the egg, egg yolk, and vanilla until combined, scraping down the bowl as needed.
- In a separate medium bowl, whisk together the flour, baking soda, and salt.
- Add the flour mixture to the butter mixture and mix on low just until no dry flour remains.
- Cover the dough and refrigerate for 30 minutes.
- Heat the oven to 350°F and line two large baking sheets with parchment paper.
- Scoop the dough into 2-tablespoon portions, spacing them about 2 inches apart on the baking sheets; bake one sheet at a time for 10 to 12 minutes, until the edges are lightly golden and the centers still look slightly soft.
- Let the cookies rest on the baking sheet for 5 minutes, then transfer them to a wire rack to cool.
Notes
For neatly shaped cookies, chill the dough for the full 30 minutes and remove each sheet when the edges are lightly golden while the centers still look slightly soft. Store in an airtight container at room temperature for up to 5 days; freeze baked cookies for up to 3 months. For a dairy-free option, use a plant-based butter that works for baking.
