Extra sugar and lemon zest (for rolling, optional)
Instructions
Preheat oven to 350°F and line 2 baking sheets with parchment paper.
Using a mixer on medium speed, cream the butter and sugar together just until smooth and combined (not fluffy or whipped). About a minute or so is usually plenty.
Add the egg, lemon juice, lemon zest, and vanilla. Mix for another 30 seconds to one minute, just until incorporated.
Stir in the flour, baking soda, and salt until a soft dough forms.
Using a 2 tablespoon cookie scoop, scoop dough, roll into balls, and roll in sugar and lemon zest (if using).
Place the cookies on the prepared baking sheet a couple of inches apart.
Bake cookie for 9–11 minutes, until the edges are set and centers still look soft.
Let the cookies cool on the pan for 5-10 minutes before transferring to a wire rack to cool completely. They'll be very soft just out of the oven.
Store the cookies in airtight container for 4-5 days or freeze for up to 3 months.
Notes
Use butter that’s soft but still slightly cool to the touch (not shiny or greasy) to prevent spreading.
Measure the flour correctly so the cookies aren't too thick or too thin.
Mix until just until combined at each step. Don’t overwork the dough or the texture of the cookies will be off.
If the dough feels soft or your kitchen is warm, chill the dough for 20–30 minutes before baking.
You can gently roll these cookies in sugar (and a little lemon zest) if you want a little extra crunch and flavor.
Bake until the edges are set and centers look slightly underdone for soft cookies. They'll firm up as they cool.
