Can You Microwave Starbucks Iced Coffee? How to Guide
The other day I went to Starbucks and ordered my usual Venti White Chocolate Mocha with extra whipped cream. Unfortunately, they gave it to me iced instead of hot. Instead of returning it, I decided I would just drink it.
But then I got thinking, can you microwave Starbucks iced coffee? Through research and my own experiment, I found that you can microwave Starbucks iced coffee to heat it up! The taste and aroma will change slightly, but overall it tasted very similar to ordering my coffee hot.
Of course, what steps you take will depend on a few factors.
- How watered down is the iced coffee?
- Do you have access to a fresh pot of regular coffee?
- Do you have a microwave safe mug available?
Don’t worry, we’ll look at all of these. And next time you receive the wrong drink, or just changed your mind, you’ll know exactly how you can heat up your iced coffee and still be able to enjoy it!

How Does Starbucks Make Iced Coffee?
The main reason I find it acceptable to microwave Starbucks iced coffee is because of how they make it.
A Starbucks barista will add the syrup first, followed by a heated double espresso shot. Now, instead of steaming the milk, it is poured from the jug over the syrup and espresso. Then, it’s shaken until mixed and poured into a plastic cup over ice.
A Starbucks iced coffee is simply a cold version of the hot drink, making it easier to microwave to heat it up.
Can You Reheat Starbucks Iced Coffee?
Yes, you can heat up Starbucks iced coffee in the microwave. It is safe to do so, but it will alter the original aroma and flavor of the coffee. To ensure that your coffee is heated evenly and doesn’t become contaminated by a mess, it’s best to heat it in short intervals (usually 1-2 minutes) until it reaches the desired temperature.
If you’re coffee has been sitting for over 30 minutes, it is probably watered down slightly. If you have access to a fresh pot of regular coffee, this will help get rid of that watery taste. Just add a couple tablespoons after microwaving and mix well.
How to Reheat Starbucks Iced Coffee
If you’re looking for a quick and easy way to enjoy your favorite iced coffee from Starbucks, you can easily reheat it in the microwave. Here’s how I did it:
- Pour your iced coffee into a microwave-safe mug or cup. Never microwave the original Starbucks cup.
- Place the mug or cup in the microwave and heat for 30 seconds at a time until your desired temperature is reached. Be sure to stir occasionally to prevent it from overheating.
- Let cool before drinking. Enjoy!
Note that microwaving your Starbucks iced coffee will alter its original aroma and flavor slightly, so be sure to adjust accordingly if needed. Additionally, be careful not to overheat as this can cause it to become bitter or burnt tasting.
Final Thoughts

While it may not taste exactly the same as when it was first made, reheating your iced coffee will still give you that much-needed caffeine fix.
