Step 1: Prepare the Dough

1. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
2. In a large bowl, cream the softened butter and granulated sugar until light and fluffy, about 2–3 minutes.
3. Beat in the eggs, one at a time, followed by the lemon juice, lemon zest, and vanilla extract.
4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.

Step 2: Chill the Dough

1. Cover the bowl with plastic wrap and refrigerate the dough for at least 1 hour. This step is crucial for easier handling and better cookie texture.

Step 3: Preheat the Oven and Prepare the Coating

1. Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
2. Place the powdered sugar in a shallow bowl.

Step 4: Shape and Coat the Cookies

1. Using a cookie scoop or tablespoon, scoop out small portions of dough and roll them into balls.
2. Roll each ball generously in the powdered sugar, ensuring an even coating.

Step 5: Bake

1. Arrange the coated dough balls on the prepared baking sheets, spacing them about 2 inches apart.
2. Bake for 10–12 minutes, or until the edges are set and the tops are slightly crackled. Avoid overbaking to maintain a soft texture.

Step 6: Cool and Enjoy

1. Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
2. Serve with a cup of tea or a glass of cold milk for a delightful treat.
