Melt the butter in the microwave and warm the milk until just lukewarm (this helps prevent lumps).

In a large bowl, mix the flour, sugar, and salt.

Add the eggs and melted butter, then gradually whisk in the milk to avoid lumps.

Let the batter rest for 30 minutes.

Heat a well-oiled crepe pan or nonstick skillet over high heat. Pour in some batter using a ladle.

Cook the crepes on high heat on each side until golden brown.
