McDonald's doesn't share it's recipe for their Iced Mocha Caramel Coffee. However, you can make your own at home. All that you will need is strong chilled coffee, caramel coffee syrup, cocoa powder or chocolate syrup, and heavy cream. You can add a caramel and/or chocolate drizzle on top of whipped cream too if you'd like. A great video to making this coffee is available at http://www.youtube.com/watch?v=nZyiJFn8rc8.
