01 - In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
02 - In a separate bowl, whisk the milk, eggs, melted butter, vanilla extract, lemon zest, and lemon juice until fully blended.
03 - Pour the wet mixture into the dry ingredients and gently stir until just combined; a few lumps should remain to avoid overmixing.
04 - Carefully fold the fresh blueberries into the batter to distribute evenly without crushing them.
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 hot skillet. Cook until bubbles appear on the surface and edges set, about 2 to 3 minutes.
07 - Flip each pancake and cook for an additional 1 to 2 minutes until golden brown and cooked through.
08 - Transfer cooked pancakes to a plate and loosely cover to maintain warmth. Repeat the cooking process with remaining batter.
09 - Stack pancakes, garnish with extra blueberries and optional butter, then drizzle generously with warm maple syrup before serving.
