01 - Preheat oven to 350°F. Line two baking sheets with parchment paper and set aside.
02 - In a medium bowl, whisk together the all-purpose flour, baking soda, and salt until evenly distributed. Set aside.
03 - In a large bowl using an electric mixer, beat the softened butter, granulated sugar, and packed brown sugar on medium speed until the mixture is light and fluffy, approximately 3 minutes.
04 - Add the eggs one at a time, beating well after each addition. Mix in the fresh lemon juice, lemon zest, and vanilla extract until fully combined.
05 - Gradually add the dry ingredient mixture to the wet ingredients on low speed, mixing just until the flour is incorporated. Do not overmix.
06 - Scoop tablespoon-sized portions of dough and roll each into a ball. Roll each ball in the extra granulated sugar to coat evenly, then place on the prepared baking sheets about 2 inches apart.
07 - Bake for 9 to 11 minutes, until the edges are set and lightly golden but the centers remain soft and puffy.
08 - Let the cookies rest on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely before serving or storing.
