01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - Whisk together the flour, baking powder, and salt in a medium bowl and set aside.
03 - In a large bowl, beat the softened butter and granulated sugar until light and fluffy, approximately 2 to 3 minutes.
04 - Add eggs one at a time, mixing thoroughly after each addition.
05 - Stir in the ricotta cheese, lemon zest, lemon juice, and vanilla extract until fully combined.
06 - Gradually fold the dry ingredients into the wet until just incorporated, avoiding overmixing.
07 - Drop tablespoon-sized portions of dough onto the prepared baking sheets, spacing them about 2 inches apart.
08 - Bake in the preheated oven for 13 to 15 minutes, or until the edges are lightly golden and the cookies are set.
09 - Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
10 - Whisk together powdered sugar, lemon juice, and lemon zest in a small bowl until smooth and pourable.
11 - Once fully cooled, spoon or drizzle the lemon glaze over each cookie. Let the glaze set for at least 20 minutes before serving.
