Prepare Dry Ingredients: In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
Prepare Wet Ingredients: In a separate bowl, whisk milk, ricotta, eggs, vanilla, melted butter, lemon zest, and lemon juice until well combined.
Combine Batter: Make a well in the dry ingredients and pour in the wet mixture. Stir gently until just combined; a few lumps are fine. If batter is too thick, add milk 1 tbsp at a time.
Heat Pan: Preheat a non-stick skillet or griddle over medium-low heat. Brush lightly with butter.
Cook Pancakes: Using a ⅓-cup scoop, pour batter onto the skillet. Cook 1–3 minutes per side, until pancakes are puffed, golden, and cooked through. Adjust heat if edges brown too quickly.
Serve: Stack pancakes and serve warm with maple syrup, fresh berries, or fruit compote.
