Preheat your oven to 350°F and line a baking sheet with parchment paper. This will help the cookies to cook evenly and prevent them from sticking to the pan.

Whisk together the flour, baking powder, and salt in a medium-sized bowl. Set this mixture aside for now.

In a separate large bowl, beat the butter and sugar together until they are light and fluffy. This should take about 2-3 minutes. Add the eggs, one at a time, beating well after each addition.

Next, add the lemon zest and lemon juice to the batter and mix well to combine. Gradually add the flour mixture to the batter, stirring until it is well incorporated.

Scoop the dough onto the prepared baking sheet using a cookie scoop or spoon. Space the cookies about 2 inches apart to allow for proper spreading during baking.

Bake the cookies in the preheated oven for 10-12 minutes, or until they are lightly golden around the edges. Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
