Mix flour, salt, sugar and baking powder together in a big bowl. Then add in egg, milk and melted butter. Mix until smooth.
Pour the batter into piping bag, cut a tiny hole.
Pipe the batter on the non-stick pan (or brush some butter on the pan), leave some spaces between each one. Cook under medium low heat for about 3 minutes or until there are bubbles on top and it kind of set. Then flip it over and cook for about 30 seconds. Enjoy!
