01 - In a large bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, and salt.
02 - In a separate bowl, whisk the buttermilk, eggs, melted butter, lemon zest, lemon juice, and vanilla extract until fully blended.
03 - Pour the wet mixture into the dry ingredients and stir gently until just combined, leaving some lumps; avoid overmixing.
04 - Fold in the fresh blueberries carefully to distribute evenly 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 look set, about 2 to 3 minutes. Flip and cook for 1 to 2 minutes more until golden and cooked through.
07 - Stack pancakes warm on plates, drizzle with warmed maple syrup, and garnish with extra blueberries and optional powdered sugar.
