Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.

Cream together the unsalted butter and granulated sugar in a large bowl until light and fluffy, about 3-5 minutes.

Combine the lemon zest and fresh lemon juice with the butter-sugar mixture and mix until fully incorporated.

Whisk together all-purpose flour and salt in another bowl and gradually blend into the wet ingredients, stirring until just combined.

Scoop rounded balls of dough onto the prepared baking sheets, leaving ample space for spreading.

Bake in the preheated oven for 12-15 minutes or until edges turn golden brown, then cool on sheets for about 5 minutes.
