Put the flour, salt and sugar in a big bowl.
Add in half of the milk. Mix it to a smooth batter with a whisk.
Add the rest of the milk, the two eggs, and mix.
Pour in the melted butter, make sure it has cooled. The butter is optional.
Let the batter rest for 20-30 minutes.
Heat up an 8-10 inch skillet to medium heat. Put some butter; ½-1 tsp, let it melt on the pan. You can brush it with a silicone brush so it gets evenly on the pan.
Stir your batter and take ¼- ⅓ cup and pour it into the pan. You can give it a whirl if it does not spread out evenly.
You can turn your pancake when the bottom has some color and the center is set.
Give your batter a stir between every pancake since the flour sinks to the bottom.
