In a mixing bowl, whisk together the flour, sugar, and salt. Create a well in the center, add eggs, and mix until thick and lumpy.

Gradually pour in the milk while whisking to achieve a smooth consistency.

Add melted butter and whisk until fully combined. Let the batter rest for 30 minutes.

Heat a non-stick skillet over medium-high heat and pour a small ladle of batter into the center. Swirl to coat the pan in a thin layer.

Cook for 1-2 minutes until golden, then flip carefully and cook the other side for 30 seconds.

Transfer cooked crepes to a plate and keep warm with a kitchen towel while repeating with remaining batter.
