A caramel swirl iced coffee is a caramel iced coffee with a fancier name! This recipe calls for drizzling the caramel around the edge of glass allowing it to fall in and combine with the milk and coffee to infuse the drink with that delicious caramel. There are versions where the caramel is the last thing that gets added and "swirled" into the drink, which turns it into a swirled iced coffee. It's all the same in the end!
