10 Best Sugar-Free Drinks At Dunkin Donuts – Tasty and Healthy!

Dunkin Donuts is not only popular for its confectionery but is also famous for its drinks, such as iced coffee and other caffeinated beverages.

If you're trying to control your sugar intake or are on a keto diet, ordering at this cafe might be difficult.

Fortunately, there are various sugar-free Dunkin drinks you can order to maintain your diet. But what exactly are these drinks?

In this article, we will discuss ten sugar-free drinks at Dunkin Donuts and how they differ from Starbucks's sugar-free beverages so you can enjoy your trip to this cafe guilt-free.

Dunkin Donuts offers a wide range of sugar-free drinks, perfect for any kind of weather.

But don't be fooled by its name; even though these drinks don't have any sugar, they're still packed with flavors that even people with a sweet tooth can enjoy!

1. Regular Coffee (Hot Or Iced Coffee)

If you're looking for a versatile and sugar-free drink, Dunkin's original coffee is your best choice.

Since it's just brewed coffee, sugar isn't automatically added to it--it's up to you to mix your coffee. In addition, you also have the freedom to choose the milk on your drink.

So, if you're on a keto diet, you can ditch both milk and sugar and drink the coffee as is.

But if you're controlling your sugar and can consume milk, you can choose whatever you want to add to your drink.

Dunkin' Plain Hot Coffee

Do you love dairy? You can add whole milk or skim milk to your drink.

Are you lactose intolerant? Go for non-dairy milk like oat milk, almond milk, or coconut milk.

There are so many milk options available, and the choice is yours to make. You can even use this regular black coffee to make the original, bulletproof keto coffee[1].

All you need to do is add butter and MCT oil to your hot coffee, and you can now have the perfect keto drink.

2. Macchiato (Hot Or Iced)

Are you fond of espresso-based drinks? If so, then macchiato is probably one of your favorite drinks. But the biggest question is, can you get this drink sugar-free?

Well, of course, you can! In case you don't know, sugar is optional for macchiatos. This means you can still enjoy this drink even if you're watching your sugar intake.

One thing to note: macchiatos are supposed to be prepared with only a tiny amount of frothed steamed milk.

In the United States, most cafes serve it as an "inverse" milk latte, where the espresso is added to the top instead of the bottom of the drink.

We don't have any problem with that, but it's worth mentioning that macchiatos served in the US are not authentic.

Going back, hot and iced macchiato Dunkin Drink is served like an upside-down latte, and not like how traditional macchiatos are made.

Most stores usually serve it with sugar immediately, so tell your barista that you want it without sugar.

3. Cold Brew

We all know that caffeine can be addicting, and if you're one of those who need a strong coffee, cold brew is a great drink.

It's usually packed with more caffeine than your regular coffee and has a stronger flavor.

However, this isn't the case with Dunkin Donuts's cold brew. The Dunkin version is smoother and has a slightly sweeter flavor compared to other cafes' versions.

It's also not highly caffeinated, perfect for those not ready for caffeine overload.

Like the previous drinks, sugar is optional for this drink. It's also customizable, allowing you to create a version that's truly yours.

For example, you can add a splash of coconut milk for a fun twist. There's also an option to add sugar-free Dunkin flavor shots such as vanilla and hazelnut flavors to level up this plain drink.

4. Skim Latte

If you're cutting down on sugar because you're watching your weight, the skim milk latte is for you.

As its name implies, it's a latte using skim milk. This drink comes in a sugar-free option, so you won't have to worry about sipping extra calories.

We recommend this drink for those who are not ready for plain black coffee and like some creaminess in their cup without too many calories.

For some, this drink may be too plain and boring. Thankfully, you can add a flavor shot to this drink to spice it up a bit.

The Dunkin flavor shots are unsweetened. It also comes in various flavors, such as toasted almond, French vanilla, blueberry, and raspberry flavor.

Out of all the flavor shots, we recommend a toasted almond flavor or French vanilla for this drink.

Dunkin' Skim Milk Macchiato

5. Non-Dairy Latte

Another drink you can have in Dunkin Donuts is the non-dairy latte. It is a new and popular vegan drink served at Dunkin.

This coffee shop offers different types of dairy-free milk, including oat milk, almond milk, and coconut milk. At the same time, these lattes have fewer calories compared to a regular latte.

For example, a medium oat milk latte contains 130 calories and 5 grams of sugar only.

Like the skim milk latte, adding flavor shots, such as a hazelnut flavor shot, can make this drink even more exciting.

Make sure you ask for a flavor shot and not a flavor swirl, as many people are confused with the two.

Flavor swirls have added sugar and have syrup-like consistency, which is not recommended for those who don't want to consume sugar.

On the other hand, flavor shots are unsweetened, sugar-free syrup that can be added to various iced coffee drinks.

6. Americano (Hot Or Iced)

Another coffee drink that's perfect for people on a keto diet and those watching their sugar intake is Americano.

Instead of brewing the coffee beans or using drip coffee, this drink is made from an espresso shot mixed with hot water. This drink has no sugar content, so be ready for that strong and bitter taste.

For summer days, you can get an iced Americano instead of the hot version. You can also customize this, depending on your mood.

For example, a shot of toasted almond flavors can give this drink a smoky, nutty taste. You can also add French vanilla shots if you want a sweet, buttery taste.

Dunkin' Americano

7. Cappuccino

The next drink on our list is a cappuccino. This is an excellent choice if you love a foamy, frothy layer of milk on top of your coffee.

Traditionally, cappuccino is made in thirds with equal parts of espresso, steamed milk, and foam.

The foam gives this drink a good texture, similar to what whipped cream can add to cold beverages.

Still, for people who are lactose intolerant or vegan, this drink isn't for you. Plant-based milk alternatives can't make good foam, which makes it challenging to achieve the right consistency.

For example, using coconut milk as a substitute makes the foam easier to dissipate. This turns the cappuccino into a latte real quick.

As a keto option, you can ask for heavy cream instead of milk. This will also result in some good foam that you'd enjoy.

8. Modified Dunkaccino

While this drink isn't technically sugar-free, it's an excellent alternative for those looking for something sweet, like hot chocolate, with less sugar and calories.

It's also ideal for those who love Dunkaccino but, for some reason, can't have a lot of it anymore.

However, you should note that this isn't on Dunkin Donuts's regular menu, so you must tell the barista exactly what you want to get this drink.

To order a modified Dunkaccino, ask the barista to fill the cup halfway with hot black coffee and then fill the rest with Dunkaccino.

Unfortunately, you can't choose your milk for this drink as Dunkaccino is premixed.

If you don't have dairy, you can order a regular latte with your milk of choice and then add your own sugar-free mocha syrup.

Dunkin only serves a mocha swirl, which is not one of the sugar-free flavors, so adding your own syrup is your best bet.

9. Iced/Hot Tea

Next on our list is tea.

Dunkin Donuts has a wide range of herbal tea, including green tea, hibiscus kiss herbal infusion, bold breakfast black tea, chamomile fields herbal infusion, and cool mint herbal infusion.

These teas are served without sugar unless you request one to be added to your drink.

Dunkin's iced tea is made-to-order, unsweetened, and sweetened. For example, you can order iced green tea if it's too hot to drink hot tea.

Tea may not have as much caffeine as coffee, but it could be an excellent alternative for those who don't want to consume sugar and a solid choice of drink for kids.

Dunkin' Premium & Herbal Teas

10. Nitro Brew

Another keto-friendly drink on our list is nitro brew coffee. It's quite a popular option, thanks to its popularity on social media.

In fact, many cafes are offering this type of cold beverage. It's creamy and flavorful, as it is infused with nitrogen, hence the name, and pulled straight from the tap.

Compared to other coffee shops' nitro brews, Dunkin's is a bit stronger and bitter. It's also served cold without ice, so you don't have to worry about having a watered-down drink/

You could try this with a sugar-free flavor shot for a more fun taste. For example, you can add blueberry flavor (yes, blueberry!) to make it taste like your favorite blueberry muffin.

There are also other flavor shots you can try so that you can customize this drink depending on your taste and mood.

Dunkin' Donuts Vs. Starbucks Sugar-Free Drinks

If you're debating whether you'll go to Dunkin Donuts or Starbucks for your sugar-free drinks, let's help you settle the score.

First, you need to ask yourself, are you only getting drinks, or do you want some food to go with it?

This is an essential question because it can help you decide which is better since both coffee shops serve sugar-free drinks, and their selections are almost similar.

So, if you're planning to just get a drink, Starbucks is a better option as it comes with more choices, especially if you like tea. For coffee-based drinks, Dunkin has more options.

If you're planning to get some snacks, we suggest going to Dunkin. It has a wide range of bread and pastries, such as bagels, English muffins, and more.

They even serve some with cream cheese, which we think is a great partner with coffee.
