01 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
02 - In a separate bowl, whisk the buttermilk, milk, eggs, melted butter, lemon zest, lemon juice, and vanilla extract until smooth.
03 - Pour the wet ingredients into the dry ingredients. Gently mix until just combined, leaving some lumps intact to avoid overmixing.
04 - Carefully fold fresh blueberries into the batter.
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 on the surface and edges set, about 2 to 3 minutes.
07 - Flip pancakes and cook for an additional 1 to 2 minutes until golden and cooked through. Repeat with remaining batter.
08 - Serve pancakes warm, stacked with extra blueberries and drizzle with maple syrup. Optionally add butter or powdered sugar.
