In a blender, combine milk and eggs, blend until foamy, approx 20 seconds or so. Turn off. Add sugar and salt; blend for a few seconds turn off. Add melted butter and vanilla, blend a few seconds turn off. Add flour, blend until all mixed. Use a small Tefal frying pan (measured 6-1/2 on bottom, 9-1/2 or so across top) spray it with non-stick Butter Flavor cooking spray. Heat it on medium-high heat. Use a 1/3-cup measuring cup and dump crepe mixture into pan, swirl around real quickly to coat bottom of pan. Use a silicon spatula to lift edges of crepe and to form round if any stray edges, it will start to bubble, not much, but its safe to flip when you see edges on underside becoming brown. Just flip with plastic spatula. So once first side cooked, flip and cook about 2 minutes or so, transfer to plate and continue with rest of batter.
