Vanilla syrup is a type of [ingredient=simple-syrup simple syrup] flavored with vanilla, usually the [ingredient=vanilla-bean vanilla bean] over [ingredient=vanilla-extract vanilla extract]. Vanilla simple syrup can be made by adding a split vanilla bean to simple syrup once it's off the heat. Cover the pan and let the bean steep for 20-30 minutes, until cool. 

Vanilla extract can be added to cooled simple syrup, though it will affect the color and not have quite the aromatic punch.
