Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.

2. Cream Butter and Sugar
In a large bowl, beat the softened butter and granulated sugar together until light and fluffy.

3. Add Wet Ingredients
Mix in the eggs, one at a time, followed by the vanilla extract, lemon zest, and lemon juice. Beat until well combined.

4. Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.

5. Shape the Cookies
Scoop tablespoon-sized portions of dough and roll into balls. Place them on the prepared baking sheet about 2 inches apart.

6. Bake
Bake for 10-12 minutes or until the edges are lightly golden. Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack.

7. Prepare the Glaze
In a small bowl, whisk together powdered sugar, lemon juice, and lemon zest until smooth. Adjust the consistency with more lemon juice or powdered sugar, if needed.

8. Glaze the Cookies
Once the cookies are completely cool, drizzle or spread the lemon glaze over the tops. Let the glaze set for 10 minutes before serving.
