Preheat your oven to 350°F (175°C). This step is crucial to ensure your cookies bake evenly.
In a large mixing bowl, cream together the softened butter and sugar until light and fluffy. This usually takes about 2-3 minutes.
Add in the eggs, lemon juice, and lemon zest. Beat until well combined, ensuring that all ingredients are thoroughly mixed.
Gradually stir in the all-purpose flour, baking powder, and salt until a dough forms. Be careful not to overmix, as this can lead to tough cookies.
Roll the dough into tablespoon-sized balls and place them on lightly greased cookie sheets, leaving space for spreading.
Flatten each ball with a glass dipped in sugar for a sweet touch.
Bake for 9-10 minutes, or until the bottom is barely light brown. Keep an eye on them to prevent overbaking!
Allow the cookies to sit on the pan for 3-4 minutes before transferring them to cooling racks.
Once the cookies are completely cooled, prepare the frosting by beating together the softened butter, powdered sugar, salt, lemon zest, and lemon juice until creamy.
If the frosting is too thick, add milk one tablespoon at a time until you reach your desired consistency.
Frost the cooled cookies using a piping bag with a 1M star tip for a decorative touch, or simply spread the frosting with a spatula.
Notes
For a tangier flavor, increase the amount of lemon zest in both the cookie dough and frosting.
