01 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
02 - In a separate bowl, whisk buttermilk, milk, eggs, melted butter, lemon zest, lemon juice, and vanilla extract until smooth.
03 - Pour the wet ingredients into the dry ingredients and gently mix until just combined, leaving a few lumps.
04 - Carefully fold fresh blueberries into the batter to avoid breaking them.
05 - Heat a non-stick 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 and edges are set, approximately 2-3 minutes.
07 - Flip and cook for an additional 1-2 minutes until golden and cooked through. Repeat with remaining batter.
08 - Stack pancakes warm with extra blueberries and drizzle generously with maple syrup. Optionally add powdered sugar or butter.
