01 - In a large mixing bowl, thoroughly whisk together flour, granulated sugar, baking powder, baking soda, and salt.
02 - In a separate bowl, whisk buttermilk, eggs, melted unsalted butter, and vanilla extract until smooth and well blended.
03 - Pour the wet ingredients into the dry mixture and gently stir until just incorporated. Batter should remain slightly lumpy.
04 - Carefully fold the blueberries into the batter to distribute evenly without breaking them.
05 - Place a non-stick skillet or griddle over medium heat and lightly grease with additional unsalted butter.
06 - Portion approximately 1/4 cup of batter per pancake onto the heated surface. Cook for 2 to 3 minutes, until bubbles form on the surface and edges appear set.
07 - Carefully flip each pancake and cook for an additional 2 to 3 minutes, until golden brown and cooked through.
08 - Repeat frying process with remaining batter, keeping finished pancakes warm. Serve immediately with maple syrup, fresh blueberries, or powdered sugar as desired.
