Pour hot coffee into a liquid measuring cup and stir in caramel sauce and sugar until completely dissolved. Add cold milk and optional heavy cream.
Add ice to a 16-ounce cup and pour latte over the top of the ice.
Top with whipped cream if desired, serve and enjoy!
Notes
Approximate nutritional information was calculated using 2% milk and does not contain optional heavy cream or any toppings. To Make a Frappuccino: Make the latte recipe as written, but double the sugar and use a large heaping tablespoon of caramel sauce (blending with ice dilutes the sweetness and flavor so you want the drink a little extra sweet to start) and then add the coffee mixture to your blender with ice and blend until well-mixed and frosty.
