01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well blended.
03 - In a large bowl, beat the softened butter and granulated sugar together until light and fluffy, approximately 2-3 minutes.
04 - Add the egg, ricotta cheese, lemon zest, lemon juice, and vanilla extract to the butter mixture. Beat until thoroughly combined and smooth.
05 - Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Avoid overmixing to maintain tender texture.
06 - Drop rounded tablespoonfuls of dough onto the prepared baking sheets, spacing about 2 inches apart to allow for spreading.
07 - Bake for 13-15 minutes until the edges are lightly golden. Allow cookies to cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely.
08 - Whisk together powdered sugar, lemon juice, and lemon zest in a small bowl until smooth and pourable. Adjust consistency with additional lemon juice if needed.
09 - Once cookies have cooled completely, drizzle or spoon the glaze over each cookie. Allow the glaze to set before serving.
