Prepare the Crepe Batter. In a mixing bowl, whisk together flour, eggs, milk, melted butter, and salt until smooth and well combined. Let the batter rest for 10-15 minutes to allow any bubbles to dissipate.
Cook the Crepes. Heat a non-stick skillet or crepe pan over medium heat and lightly grease with butter or cooking spray. Pour a small amount of batter into the pan, swirling it around to coat the bottom evenly. Cook for 1-2 minutes until the edges begin to lift and the bottom is lightly golden. Flip the crepe and cook for an additional 1-2 minutes until cooked through. Repeat with the remaining batter.
Fill and Fold. Once cooked, fill each crepe with your desired filling, placing it in the center of the crepe. Fold the sides over the filling to create a pocket or roll the crepe into a cylinder shape.
Serve and Enjoy. Transfer the filled crepes to a serving plate and top with your favorite toppings, such as fresh fruit, powdered sugar, or a drizzle of syrup. Serve immediately and enjoy the deliciousness!
