In a large mixing bowl, lightly whisk the milk and the eggs together. Once combined, add in the flour, sugar, and salt. Stir together until the batter is smooth.
Lightly spray 6 inch ramekins with nonstick cooking spray. Fill each ramekin with batter, filling no more than halfway.
Air fry at 380 degrees F for 12-14 minutes. You may need to turn them over halfway to ensure they cook evenly.
