Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
02 -
In a large bowl, cream together the softened butter and granulated sugar until light and fluffy, about 3 minutes. Beat in the egg, lemon zest, and lemon juice until fully combined.
03 -
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until a dough forms.
04 -
Roll the dough into 1-inch balls and place them on the prepared baking sheets, about 2 inches apart. Flatten each ball slightly with your fingers or the bottom of a glass.
05 -
Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden. The centers may appear soft, but they will firm up as they cool. Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
06 -
In a medium bowl, beat the softened butter until creamy. Gradually add the powdered sugar, 1 cup at a time, beating well after each addition. Mix in the lemon zest and fresh lemon juice until smooth and creamy. If the frosting is too thick, add heavy cream, 1 tablespoon at a time, until you reach the desired consistency.

Once the cookies have cooled completely, spread or pipe the lemon frosting onto each cookie. Top with a sprinkle of extra lemon zest for garnish, if desired.
