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 beat the softened butter, granulated sugar, and brown sugar until light and fluffy.
04 - Add the eggs one at a time, beating well after each addition. Mix in the lemon juice, lemon zest, and vanilla extract until fully combined.
05 - Gradually add the dry ingredient mixture to the wet ingredients, 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 the 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 - Let the cookies cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
