In a blender, combine the milk, flour, eggs, sugar, vanilla extract, and salt.
Blend until the batter is completely smooth, scraping down the sides if necessary.
Let the batter rest for at least 5 minutes at room temperature, or up to 2 hours in the refrigerator. This allows the gluten to relax, resulting in more tender crepes.
Heat a lightly oiled 8-inch non-stick skillet or crepe pan over medium heat. The pan is ready when a drop of water sizzles and evaporates almost immediately.
Pour about ¼ cup of batter onto the hot pan, immediately tilting and swirling the pan to spread the batter thinly and evenly.
Cook for 2-3 minutes, or until the edges are set and the underside is lightly golden brown.
Carefully flip the crepe with a spatula and cook for another 1-2 minutes, or until the second side is also lightly golden brown.
Slide the cooked crepe onto a plate and repeat with the remaining batter, stacking the crepes as you go. You may need to add a small amount of oil to the pan between crepes to prevent sticking.
