01 - In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt until evenly mixed.
02 - In a separate bowl, blend ricotta, egg yolks, milk, lemon zest, lemon juice, vanilla extract, and melted butter until smooth.
03 - Using a clean bowl, beat egg whites until soft peaks form.
04 - Stir the ricotta mixture into the dry ingredients until just combined, avoiding overmixing.
05 - Gently fold the whipped egg whites into the batter until fully incorporated without deflating.
