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

In a mixing bowl, cream together 1 cup of softened unsalted butter and ½ cup of sifted powdered sugar until light and fluffy.

Add 2 tablespoons of fresh lemon juice and the zest of 2 lemons, mixing until well incorporated.

Whisk together 2 cups of all-purpose flour and a pinch of salt, then gradually incorporate into the wet mixture.

Shape the dough into small balls, about 1 inch in diameter, and place them on the prepared baking sheet.

Bake for 12 to 15 minutes until lightly golden around the edges.

Cool on the baking sheet for 5 minutes, then transfer to a wire rack and dust with powdered sugar.
