01 - In a large mixing bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
02 - In a separate bowl, whisk milk, eggs, melted butter, vanilla extract, lemon zest, and lemon juice until homogenous.
03 - Pour the wet mixture into the dry ingredients and gently stir until just combined, leaving some lumps to preserve fluffiness.
04 - Carefully fold fresh blueberries into the batter to prevent breaking them.
05 - Heat a nonstick skillet or griddle over medium heat and lightly grease with butter or oil.
06 - Spoon approximately 1/4 cup batter per pancake onto the skillet. Cook 2 to 3 minutes until bubbles form on surface and edges appear set.
07 - Turn pancakes and cook for an additional 1 to 2 minutes until golden brown and fully cooked through.
08 - Transfer cooked pancakes to a plate and cover loosely to retain heat. Repeat with remaining batter and serve stacked topped with extra blueberries, optional butter, and warmed maple syrup.
