01 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until evenly distributed.
02 - In a separate bowl, whisk buttermilk, eggs, melted butter, lemon zest, lemon juice, and vanilla extract until thoroughly combined.
03 - Pour the wet mixture into the dry ingredients and gently fold until just combined. Some lumps are acceptable to avoid overmixing.
04 - Carefully fold fresh or frozen blueberries into the batter 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 skillet. Cook until bubbles appear on the surface and edges set, approximately 2 to 3 minutes. Flip and cook for another 1 to 2 minutes until golden and cooked through.
07 - Continue cooking remaining batter, greasing the pan as necessary. Serve pancakes warm, stacked and drizzled with maple syrup. Garnish with extra blueberries and powdered sugar if desired.
