01 - Whisk together flour, sugar, baking powder, baking soda, and salt in a large bowl until evenly distributed.
02 - In a separate bowl, whisk buttermilk, eggs, melted butter, vanilla extract, lemon zest, and lemon juice until fully incorporated.
03 - Pour wet ingredients into dry ingredients and stir gently until just combined. Small lumps are acceptable; avoid overmixing to prevent tough pancakes.
04 - Gently fold fresh blueberries into the batter until evenly distributed.
05 - Heat a nonstick skillet or griddle over medium heat and lightly coat with butter or oil.
06 - Pour approximately 1/4 cup batter per pancake onto the skillet. Cook for 2-3 minutes until surface bubbles form and edges appear set. Flip and cook an additional 1-2 minutes until golden brown and cooked through.
07 - Repeat with remaining batter, applying additional grease to the pan as needed between batches.
08 - Stack warm pancakes and serve with warm maple syrup, additional fresh blueberries, and a sprinkle of lemon zest if desired.
