Preheat oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
In a large bowl, cream together the granulated sugar and softened butter until light and fluffy.
Beat in the eggs one at a time, then stir in the ricotta cheese, milk, vanilla extract, lemon zest, and lemon juice until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
Pour the batter into the prepared cake pan and spread evenly.
Bake for 45-50 minutes, or until a wooden skewer inserted into the center comes out clean.
Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
For the glaze: In a small bowl, whisk together powdered sugar, lemon juice, and milk until smooth. Adjust milk for desired consistency. Drizzle over the cooled cake.
Notes
