01 - Whisk together ricotta, egg yolks, milk, melted butter, lemon zest, lemon juice, and vanilla extract in a large bowl until completely smooth and creamy.
02 - Mix flour, sugar, baking powder, baking soda, and salt in a separate bowl to ensure even distribution of leavening agents.
03 - Gently fold the dry ingredients into the wet mixture until just combined. The batter should remain slightly lumpy—do not overmix as this will toughen the pancakes.
04 - Using a hand mixer or whisk, beat the egg whites in a clean bowl until soft peaks form. The whites should hold their shape when the whisk is lifted.
05 - Gently fold the beaten egg whites into the pancake batter using a spatula, using sweeping motions to preserve as much air as possible for maximum fluffiness.
06 - Preheat a nonstick skillet or griddle over medium heat. Lightly grease with butter or oil, wiping away any excess with a paper towel.
07 - Pour 1/4 cup of batter per pancake onto the skillet. Cook for 2–3 minutes until bubbles form across the surface and edges appear set. Flip and cook for an additional 1–2 minutes until golden brown and cooked through.
08 - Stack pancakes warm on plates. Top generously with fresh mixed berries, drizzle with maple syrup, and dust with powdered sugar if desired. Serve immediately.
