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