Blender It Up: In a blender, combine the flour, eggs, milk, melted butter, sugar (if using), salt, and vanilla extract. Blend on high until the batter is smooth, and there are no lumps—about 20-30 seconds. Scrape down the sides of the blender as needed.

Chill the Batter: Allow the batter to rest for about 10-15 minutes. This helps achieve a tender crepe texture.

Heat the Pan: Preheat a non-stick skillet or crepe pan over medium heat. Lightly grease it with butter or oil using a paper towel.

Cook the Crepes: Pour about ¼ cup of batter into the center of the pan. Quickly tilt and swirl the pan to spread the batter evenly into a thin layer. Cook for about 1-2 minutes until the edges be to lift and the bottom is lightly golden.

Flip and Finish: Carefully flip the crepe with a spatula and cook for another 30 seconds. Transfer to a plate and repeat with the remaining batter, stacking the cooked crepes on top of each other.

Serve and Enjoy: Fill your crepes with your favorite toppings, fold them, and serve immediately!
