01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt until well blended.
03 - In a large bowl, beat butter and sugar with an electric mixer on medium speed until light and fluffy, approximately 2-3 minutes.
04 - Add egg to butter mixture and beat until fully incorporated. Mix in ricotta cheese, lemon zest, lemon juice, and vanilla extract until smooth and uniform.
05 - Gradually add dry ingredients to wet ingredients, mixing on low speed until just 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 and centers are set. Cookies will remain soft and cake-like when removed from oven.
08 - Let cookies rest on baking sheets for 5 minutes, then transfer to wire rack to cool completely before glazing.
09 - Whisk together powdered sugar, 2-3 tablespoons lemon juice, and lemon zest in small bowl until smooth and drizzling consistency is achieved.
10 - Once cookies are completely cool, spoon or drizzle glaze over each cookie. Allow glaze to set at room temperature for 15-20 minutes before serving.
