In a mixing bowl, whisk together the flour and salt.

In another bowl, lightly beat the eggs, then add milk and melted butter; mix well.

Gradually combine the wet ingredients into the dry mixture until smooth.

Let the batter rest for at least 30 minutes.

Preheat a non-stick skillet over medium heat and lightly grease it.

Pour about half a cup of batter into the skillet, swirling to coat evenly. Cook for about 2 minutes until edges lift slightly; flip carefully.

Transfer cooked crêpes to a plate, cool slightly, then fill with desired toppings.
