Preheat your oven to 350F and line a baking sheet with parchment paper.
In a mixing bowl, combine the flour, baking powder, baking soda, and salt.
In a separate bowl, beat the butter, sugar, egg, lemon zest, lemon juice, and vanilla extract together until well combined.
Add the wet ingredients to the dry ingredients and mix until a dough forms.
Use a cookie scoop or spoon to form the dough into 24 balls and place on the prepared baking sheet.
Bake for 12-15 minutes, or until the edges are golden brown.
Remove from the oven and let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
