In a large mixing bowl, combine flour, sugar, baking soda, salt, and baking powder. Whisk thoroughly for about 30 seconds until well mixed.

In a separate bowl, whisk the egg gently, then add buttermilk and vegetable oil, stirring until smooth.

Pour the wet mixture into the dry ingredients. Stir gently until just combined; a few lumps are okay.

Heat a griddle over medium heat (350°F/175°C) and lightly coat it with vegetable oil or butter.

Let the batter rest for 5-10 minutes to improve texture and fluffiness.

Pour ¼ cup of batter onto the griddle. Cook until bubbles form on the surface, then flip and cook until golden brown.

Serve hot with butter and maple syrup.
