In a large mixing basin, combine all-purpose flour, granulated sugar, baking powder, baking soda, and a sprinkle of kosher salt. Ensure that all components are uniformly distributed.
In a separate dish, mix together the buttermilk, big eggs, melted unsalted butter, and pure vanilla essence until thoroughly combined.
Pour the wet ingredients into the dry mixture, stirring gently until just incorporated. Take care not to overmix; a few lumps are absolutely OK.
Preheat a nonstick skillet or griddle to medium heat. Lightly coat the surface with melted butter or cooking spray.
Using a ΒΌ cup measuring cup, pour the pancake batter onto the griddle, producing small to medium circles. Allow room between each pancake for easy flipping.
Cook the pancakes for about 2-3 minutes on the first side, or until bubbles appear on the surface. Flip the pancakes and heat for another 1-2 minutes, or until golden brown and fully done.
Transfer the cooked pancakes to a heated platter and loosely cover with aluminum foil to keep warm while you prepare the remaining batter.
Serve the Fluffy Pancakes with a sprinkle of maple syrup and a handful of fresh berries for a punch of sweetness.
