01 - Whisk together flour, sugar, baking powder, baking soda, and salt in a large mixing bowl.
02 - In a separate bowl, whisk milk, eggs, melted butter, vanilla extract, lemon zest, and lemon juice until thoroughly combined.
03 - Pour the wet ingredients into the dry ingredients and gently mix until just combined, leaving some lumps to avoid overmixing.
04 - Fold fresh blueberries carefully into the batter without deflating it.
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 skillet. Cook until bubbles form on the surface and edges begin to set, approximately 2 to 3 minutes.
07 - Flip pancakes and cook for an additional 1 to 2 minutes until golden brown and cooked through.
08 - Transfer cooked pancakes to a plate and cover loosely to maintain warmth. Repeat until all batter is used.
09 - Stack pancakes, garnish with extra blueberries and optional butter, then drizzle generously with warm maple syrup.
