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

Cream together the softened unsalted butter and powdered sugar until light and fluffy, about 2-3 minutes.

Add the fresh lemon juice and lemon zest, mixing until smooth and fragrant.

In a separate bowl, whisk together the all-purpose flour and salt. Slowly add to the butter mixture until a soft dough forms.

Use a tablespoon to shape the dough into balls, placing them 2 inches apart on the baking sheet.

Bake for 12-15 minutes until edges are lightly golden and centers look set but soft.

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