Melted salted butter on a pan, set aside.

In a bowl, add the flour, pour the water and mix well (we need a liquid enough mixture, so just add the water until you think it's enough but not too liquid).

Add the melted salted butter into the mixture and stir it until combine.

Prepare the pan with cooking spray, pour about one ladle spoon of the mixture into the pan and cook it until the angle of the pancake become crispy then return it into other side and cook until it's done.

You can serve it with jam or else topping as you like
