Preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper.

Whisk together the dry ingredients in a medium bowl: flour, baking soda, baking powder, and salt.

Cream the butter and granulated sugar in a large bowl until fluffy and pale. Beat in the egg, vanilla extract, lemon juice, and lemon zest.

Combine the dry ingredients with the wet mixture gradually. Stir until you achieve a soft, slightly sticky dough.

Scoop tablespoon-sized portions of dough, roll them into balls, and coat each in granulated sugar. Place them on the baking sheets.

Bake in the oven for 9–11 minutes, until the edges are just lightly golden.

Cool the cookies on the pan for about 5 minutes before transferring them to a wire rack to cool completely.
