Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
Add the ricotta cheese, egg, lemon zest, lemon juice, and vanilla extract to the mixture and blend until well combined.
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Be careful not to overmix.
Gently fold in the fresh blueberries, taking care not to break them apart.
Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake in the preheated oven for 12-15 minutes or until the cookies are lightly golden around the edges.
Once baked, remove them from the oven and allow them to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Optional: Dust with powdered sugar before serving for an extra touch of sweetness.
