Step-by-Step Method

1. Prepare the Dough

1. In a mixing bowl, cream the softened butter and sugar together until light and fluffy.
2. Add the egg and mix until well incorporated.
3. Gradually sift in the flour and baking powder, mixing continuously to form a smooth dough.
4. Add the lemon zest and mix until evenly distributed. For an extra lemony kick, you can also add 1 tablespoon of limoncello (optional).

2. Chill the Dough

1. Wrap the dough in plastic wrap and refrigerate for about 30 minutes to firm up. This makes it easier to handle and shape.

3. Shape the Cookies

1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Remove the dough from the refrigerator and form small, slightly flattened balls with your hands.
3. Place the balls on the prepared baking sheet, leaving a little space between each.

4. Bake the Cookies

1. Bake in the preheated oven for about 15 minutes, or until the cookies turn a light golden brown.
2. Remove from the oven and let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack.

5. Add the Finishing Touch

1. Once the cookies are completely cool, dust them generously with powdered sugar for an elegant finish.
