In a mixing bowl, whisk together 1 cup all-purpose flour, 2 tablespoons granulated sugar, 2 teaspoons baking powder, 1/2 teaspoon baking soda, and 1/4 teaspoon salt until well combined.

In a separate bowl, whisk together 1 cup buttermilk, 1 large egg, and 2 tablespoons melted unsalted butter until smooth.

Pour the wet ingredients into the dry ingredients and gently stir until just combined, being careful not to overmix.

Heat a griddle or non-stick skillet over medium heat (about 375°F) and lightly grease with butter or oil.

Using a 1/4-cup measuring cup, pour batter onto the hot griddle to form pancakes about 4 inches in diameter.

Cook for 2 to 3 minutes, or until bubbles appear on the surface and edges look set.

Carefully flip the pancakes with a spatula and cook for an additional 1 to 2 minutes, until golden brown.

Remove pancakes from the griddle, keep warm, and serve immediately with your favorite toppings.
