In a large mixing bowl, add plain flour, sugar, baking powder, and salt. Mix the dry ingredients well using a hand whisk.
Now add whisked egg, melted butter, and vanilla essence.
Using a hand whisk, mix well until all the ingredients are well combined.
Do not over-mix the batter, stir just until there are no more lumps.
Set the batter aside for 15 minutes.
Heat a non-stick pan for 5 minutes on low heat. Then turn the heat to medium and pour a small ladle full of batter. Do not spread the batter, let flow on its own and take a round shape.
Wait for a couple of minutes or until you see small bubbles appear on the surface. Slowly flip the pancake to the other side and cook for 1 more minute.
Keep the pancakes warm in a preheated oven or in a hot box until it is served.
Serve warm as breakfast with honey, fruit jam, or maple syrup. Or simply dust with icing sugar.
