In a mixing bowl, whisk together the dry ingredients: flour, sugar, baking powder, baking soda, and salt.

In another bowl, combine the wet ingredients: buttermilk, beaten egg, melted butter, and vanilla extract.

Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix; some lumps are okay.

Heat a griddle or frying pan over medium heat and lightly grease it with butter or oil.

Pour about 1/4 cup of batter onto the griddle for each pancake.

Cook until bubbles form on the surface and the edges look set, about 2-3 minutes.

Flip the pancakes and cook for another 1-2 minutes until golden brown.

Repeat with the remaining batter, greasing the griddle as needed.

Serve warm with your favorite toppings such as syrup, fresh fruit, or whipped cream.
