01 - Whisk together ricotta, egg yolks, milk, lemon zest, lemon juice, vanilla extract, and melted butter until smooth and well combined.
02 - Sift flour, baking powder, salt, and sugar in a separate bowl to ensure even distribution of leavening agents.
03 - Add dry ingredients to ricotta mixture and gently fold until just combined. Avoid overmixing to prevent tough pancakes.
04 - Beat egg whites to stiff peaks in a clean bowl. Gently fold into batter in two additions, maintaining as much air as possible for fluffy texture.
05 - Heat nonstick skillet or griddle over medium-low heat. Brush lightly with butter to prevent sticking.
06 - Pour 1/4 cup batter per pancake onto skillet. Cook 2-3 minutes until bubbles form and edges set. Flip and cook 1-2 minutes until golden brown and cooked through.
07 - Repeat with remaining batter, adding butter to skillet as needed between batches.
08 - Serve warm pancakes topped with fresh berries, maple syrup or honey drizzle, and powdered sugar dusting if desired.
