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