Combine the milk, flour, sugar, salt, eggs and 2 tablespoons of the butter in a blender and blend until smooth, about 20 seconds. Let the batter rest at room temperature for at least 15 minutes before using or transfer to a container with a lid and let rest in the refrigerator for up to 1 day.
Heat a 10-inch nonstick skillet over medium heat. Lightly brush with some of the remaining melted butter. Add 3 to 4 tablespoons of batter and swirl the skillet so the batter completely covers the bottom. Cook until the underside of the crepe is golden brown, 2 to 3 minutes. Loosen the edge of the crepe with a rubber spatula, then with your fingertips, quickly flip. Cook 1 minute more. Slide the crepe out of the skillet and repeat with the remaining batter, coating the skillet with butter as needed. Stack the finished crepes directly on top of each other.
