Combine brown sugar and butter in a saucepan over medium heat. Stir continuously until the butter is melted and sugar is dissolved. Whisk in condensed milk, corn syrup, and vanilla and bring to a boil, stirring continuously. Place a candy thermometer in the caramel mixture and continue to boil until the caramel reaches 225℉ or soft ball stage (when a drop into cold water forms a soft ball). Let caramel cool in the pan for 3-5 minutes, then pour over cheesecake. Smooth and let set until cool.
