Whisk flour and salt in a bowl. In a separate bowl, beat eggs, milk, melted butter, sugar, and vanilla until smooth.
Pour the wet into the dry. Whisk until no lumps remain, then rest the batter 10–15 minutes if you have time. If not, that’s fine—you’re busy, I get it.
Heat a nonstick skillet over medium heat. Lightly grease with a touch of oil or butter.
Pour about 1/4 cup of batter into the center. Tilt the pan in a circular motion to spread thinly.
Cook 1–2 minutes until edges lift and the bottom is golden. Flip and cook 30 seconds more. Transfer to a plate.
Repeat with remaining batter, stacking as you go. Keep warm if needed with a low oven or by covering loosely.
