Add the eggs, softened cream cheese, and salt to a blender and blend until the batter is completely smooth no cream cheese bits.
Let the batter rest for 2 minutes while you warm your skillet over medium-low heat; this tiny pause helps the bubbles settle so the crepes cook more evenly.
Add a little butter or tallow to the pan and swirl to coat, then pour in a small amount of batter (about 2–3 tablespoons for an 8-inch pan, or closer to 1/4 cup for a 10-inch pan).
Immediately tilt and swirl the pan so the batter spreads into a thin, even layer.
Cook for about 60–90 seconds, until the edges look set and you can slide a spatula underneath without sticking.
Flip gently and cook the second side for 20–40 seconds, just until lightly golden.
Transfer to a plate and repeat, greasing the pan as needed.
Stack the crepes as you go (they stay soft and warm like this), then fill, fold, and serve.
