Pour milk over ice. Add the vanilla extra and stir. If you're using sweetener, add it now.
Pour a shot of espresso into the milk.
Using a straw or spoon, mix the iced vanilla latte. Serve and enjoy.
If you don't have an espresso machine, use brewed coffee instead. I prefer to use about ½ cup of double-strength brewed coffee and cool it down in the fridge before making the latte.Consider drinking your latte with a glass straw to help protect your teeth.
