01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
03 - In a large bowl, use an electric mixer to cream the softened butter, granulated sugar, and brown sugar until light and fluffy.
04 - Beat in the eggs one at a time, mixing well after each addition. Blend in the lemon juice, lemon zest, and vanilla extract until fully combined.
05 - Gradually add the dry ingredients to the wet mixture, mixing just until incorporated. Do not overmix.
06 - Scoop tablespoon-sized portions of dough and roll each ball in the extra granulated sugar. Place on prepared baking sheets about 2 inches apart.
07 - Bake for 9 to 11 minutes, until the edges are set but the centers remain soft.
08 - Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
