01 - Whisk together all-purpose flour, granulated sugar, baking powder, baking soda, and salt in a large bowl until evenly mixed.
02 - In a separate bowl, whisk buttermilk, eggs, melted butter, lemon zest, lemon juice, and vanilla extract until fully combined.
03 - Pour the wet mixture into the dry ingredients and gently stir until just combined, leaving some lumps to maintain batter lightness.
04 - Carefully fold fresh blueberries into the batter to distribute evenly without crushing.
05 - Heat a nonstick skillet or griddle over medium heat and lightly grease with butter or oil to prevent sticking.
06 - Pour 1/4 cup of batter per pancake onto the skillet. Cook until bubbles form on the surface and edges set, approximately 2 to 3 minutes. Flip and cook the opposite side for 1 to 2 minutes until golden and cooked through.
07 - Continue with remaining batter, greasing skillet as needed. Serve the pancakes warm, stacked, drizzled with maple syrup, and optionally garnished with extra blueberries and powdered sugar.
