01 - In a substantial mixing vessel, thoroughly combine all-purpose flour, granulated sugar, baking powder, baking soda, and salt.
02 - In a separate receptacle, whisk together buttermilk, eggs, and melted unsalted butter with vanilla extract until a homogenous blend is achieved.
03 - Gently introduce the wet components into the dry mixture, stirring minimally until just combined. The batter is expected to retain some minor lumps.
04 - Carefully fold the blueberries into the batter, ensuring even distribution without compromising their structure.
05 - Heat a non-stick skillet or griddle over medium heat. Lightly coat the surface with additional unsalted butter.
06 - Dispense approximately 1/4 cup of batter per pancake onto the heated surface. Cook for 2 to 3 minutes, observing for bubble formation and set edges.
07 - Flip each pancake meticulously and continue cooking for an additional 2 to 3 minutes, until perfected to a golden-brown hue and cooked through.
08 - Repeat the frying process with any remaining batter, maintaining warmth for finished pancakes. Serve promptly with preferred accompaniments such as maple syrup, fresh blueberries, or powdered sugar.
