In a large bowl, whisk together the flour, sugar, and salt.
Make a well in the center and add the eggs.
Gradually pour in the milk while whisking to combine.
Stir in the melted butter until smooth.
Let the batter rest for about 30 minutes.
Heat a non-stick skillet over medium heat and add a little butter.
Pour about 1/4 cup of batter into the skillet, swirling to coat the bottom.
Cook for 1-2 minutes or until the edges start to lift.
Flip the crepe and cook for another minute until golden.
Repeat with the remaining batter, stacking the cooked crepes on a plate.
