01 - Whisk together flour, sugar, baking powder, baking soda, and salt in a medium bowl.
02 - In a large bowl, blend ricotta, milk, egg yolks, melted butter, vanilla extract, lemon zest, and lemon juice until smooth.
03 - Fold the dry mixture gently into the wet mixture until just combined, avoiding overmixing.
04 - Whisk egg whites in a clean bowl until soft peaks form, then fold carefully into the batter to maintain lightness.
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 1–2 minutes until golden and cooked through.
07 - Plate pancakes warm, topping with mixed berries, drizzling with maple syrup or honey, and optionally dusting with powdered sugar.
