Heat your oven to 200 degrees (to keep your cooked pancakes warm).

Whisk the flour, sugar, baking powder, baking soda, and salt together in a large bowl.

In a medium bowl, whisk the buttermilk, melted butter, and egg together.

Make a well in the center of the flour mixture, pour the buttermilk mixture into the well, and gently whisk together until just incorporated with a few lumps remaining (don't overmix.)

Heat your skillet over medium heat for about 5 minutes before pouring your batter in.

Brush the bottom of the pan with a thin layer of oil.

Cook pancakes until golden brown on both sides.
