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

In a mixing bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

In another bowl, cream the softened butter and granulated sugar together using an electric mixer until light and fluffy.

Add the eggs one at a time, mixing well after each addition. Then mix in the lemon juice, lemon zest, and vanilla extract.

Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Drop tablespoon-sized balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden.

While the cookies are baking, whisk together the powdered sugar and lemon juice in a small bowl until smooth.

Once the cookies are done, remove them from the oven and let them cool for a few minutes on the baking sheet before transferring to a wire rack.

Drizzle the lemon glaze over the cooled cookies and allow it to set before serving.
