01 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
02 - In another bowl, blend the ricotta, egg yolks, milk, melted butter, lemon zest, lemon juice, and vanilla until smooth.
03 - Add the wet mixture to the dry ingredients and gently stir until just incorporated without overmixing.
04 - Beat the egg whites until stiff peaks form, then carefully fold them into the batter in two additions to retain airiness.
05 - Heat a nonstick skillet or griddle over medium heat and lightly grease with butter or oil.
06 - Pour 1/4 cup of batter per pancake onto the skillet. Cook 2–3 minutes until bubbles form and edges set, then flip and cook another 1–2 minutes until golden.
07 - Continue cooking remaining batter, greasing the pan as needed.
08 - Plate the pancakes warm, drizzled with maple syrup and garnished with fresh berries and powdered sugar if desired.
