Prepare the Batter: In a large mixing bowl, whisk together the 1 cup all-purpose flour, 2 large eggs, and half of the 1 ¼ cups milk until smooth. Gradually add the remaining milk while whisking to prevent lumps.
Add Flavor & Rest: Stir in the melted 2 tablespoons unsalted butter, ½ teaspoon salt, and (if making sweet crêpes) 1 tablespoon sugar and 1 teaspoon vanilla extract. Let the batter rest for 15-30 minutes for the best texture.
Heat the Pan: Heat a non-stick skillet or crêpe pan over medium heat. Lightly grease it with Extra butter or oil for cooking.
Cook the Crêpes: Pour about 1/4 cup of batter into the pan, swirling it quickly to create a thin, even layer. Cook for 1-2 minutes, until the edges lift slightly and the bottom is golden brown. Flip and cook for 30 seconds to 1 minute on the other side.
Repeat & Stack: Transfer cooked crêpes to a plate and repeat with the remaining batter, greasing the pan as needed.
Serve & Enjoy: Fill with your favorite toppings—Nutella, jam, fresh fruit, or ham & cheese—then fold or roll the crêpes and enjoy!
