Combine flour, powdered sugar, and salt in a mixing bowl.

Add milk and egg to the dry ingredients.

Mix until the batter is smooth and free of lumps.

Heat a lightly oiled frying pan over medium-high heat until hot.

Pour about 1/4 cup of batter into the hot pan, immediately remove from heat.

Swirl the pan to spread the batter thinly and evenly.

Cook until the crepe is dry and lightly golden on the bottom.

Flip the crepe and cook briefly on the other side.

Remove the crepe from the pan and place it on a plate.

Repeat with the remaining batter.
