01 - In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt until evenly mixed.

03 - Pour the wet mixture into the dry ingredients and gently stir until just combined; leave some lumps for tenderness.
04 - Fold fresh blueberries carefully into the batter to avoid breaking them.
05 - Heat a large nonstick skillet or griddle over medium heat and grease lightly with butter or oil.

08 - Continue with remaining batter, greasing skillet as needed. Serve warm with maple syrup, extra blueberries, and a sprinkle of powdered sugar if desired.
