You can use caramel brulee sauce as a topping for this simple recipe, or even regular caramel syrup. A drizzle of caramel sauce might be the most common topping, but you can also turn it into a sweet and salty topping by sprinkling some sea salt on light brown sugar on top.  If you want to cut back on a bit of the caramel flavoring, it's easy to do so. Simply swap out the caramel topping, and use fudge or hot fudge sauce instead. A little drizzle of that chocolate goodness is a good pairing with the rest of the ingredients of this simple copycat drink.
