Since going keto, I know how tough it is to find the best keto drinks possible at your fave cafes - and the disappointment of discovering a limited (or nonexistent) selection.

Below is a list of the best keto-friendly Dunkin drinks so you can still enjoy sipping on Dunkin without worrying about breaking ketosis.

1. Drip Coffee 

Dunkin Donuts Drip Coffee

Dunkin’s drip coffee has 0 grams of carbs and fats, and is completely sugar free. As long as this hot coffee is served black (with no whole/skim milk, or sugar), then you're set on your non-carb diet.

Dunkin uses quality assured Arabic beans, and every drip coffee has a strong and rich blend and taste.

If you don't like plain black coffee, add a little heavy cream (not whipped cream) or sugar free flavor shots to keep it keto. 

Having been on the keto diet myself, I found it hard to enjoy my usual coffee drinks without the carbs. 

The absolute best drip coffee I found for staying disciplined with every cup of joe is the ground coffee from Bulletproof. I normally add MCT oil as well. 

Barista HQ Tip: You can also add almond milk or oat milk as a dairy free milk alternative.

Try Bulletproof Coffee's Original Ground!

2. Americano 

Dunkin Donuts Americano

An Americano is essentially hot water and espresso together, so it was bound to make my list for the best keto Dunkin Donuts drinks. 

There's a medium of 65 cal in a large serving, with 3 g of fat (0 g sat), 3 g of net carbs, 10 mg of sodium, 0 g of fiber, and 1 g of protein. It's also completely sugar free.  

Barista HQ Tip: Add-ins like heavy cream, flavor shots, or sugar-free sweeteners will add a little extra flavor to your hot coffee, and they don't contain tons of carbs and are high in fat.

3. Iced Coffee

Dunkin Donuts Iced Coffee

Prefer a colder option for your keto-friendly Dunkin Donuts order? Choose an unsweetened iced coffee (ice & brewed coffee) in any Dunkin store, and you'll still be perfectly set in your keto diet.

For each large iced coffee, you'll get an average of 120 calories, 12 g of fat, 2 g of net carbs, 2 g of sugar, and 2 g of protein.  

Barista HQ Tip: Just like with hot coffee you can add sugar-free flavor shots or heavy cream to your keto iced coffee.

4. Iced Americano 

Dunkin Donuts Iced Americano with Almond Milk

An iced coffee Americano is a great option on those hot, sunny days or before a workout.

There is the same nutritional information that applies to a hot Americano, except the added ice might water down the bitterness of your drink. 

Barista HQ Tip: Choose sugar free flavor shots or sweeteners of your liking to add to this iced coffee, and opt for a coconut milk instead of skim milk to stick to your keto diet.

5. Cold Brew 

Dunkin Donuts Cold Brew

If you like cold brew coffee, then you'll already know Dunkin's Nitro cold brew coffee. Did you know that it has an average of 0 grams in carbs, sugars, and fats?

Dunkin' makes their cold brew by steeping coffee grounds for 12 hours, so it has a richer and slightly sweeter flavor. 

It is less acidic and more naturally sweet than regular coffee, making cold brew an excellent option for people on keto everywhere. 

Barista HQ Tip: Is the cold brew coffee flavor too strong? Add in some sugar free flavor shots or flavor swirls to make it a bit more drinkable but still keto.

6. Espresso 

Dunkin Donuts Espresso

Are you in a rush and need a caffeine boost? Try ordering a shot (or two) of espresso.

Stop in one of Dunkin’s 11,000 stores. These keto drinks have 0g in sugar and fat, and it only has 1 gram of net carbs, that's an average of 4-5 calories per shot. 

Barista HQ Tip: Although it's not on the menu, you can also ask staff members for espresso with ice, or you can add coconut milk to make it a coconut milk macchiato, or almond milk for a nutty taste.

7. Decaf Breakfast Black Tea 

Dunkin Donuts Iced Tea

The tea menu is a good place to experiment with sugar-free flavors, and the bold, black breakfast tea is no exception.

It has flavors of blueberry, raspberry, and coconut, this tea is not only delicious, but this keto Dunkin drink has 0 grams of net carbs, sugars, and fats.  

8. Cool Mint Herbal Infusion Tea 

Dunkin Cool Mint Tea

Stay refreshed with a cool mint herbal infusion tea combining peppermint leaves and natural herbs to offer a cool, invigorating taste.

It's caffeine-free, and it is very soothing and revitalizing to drink.

You can buy Dunkin’s tea sachets from their stores or grocery stores nationwide to enjoy this keto Dunkin drink at work or home.  

9. Harmony Leaf Green Tea 

Dunkin Donut Harmony Leaf Green Tea

Get a little kick of caffeine with the harmony leaf green tea. It has 70 mg of caffeine, and it can be perfectly paired with strawberry or raspberry flavor shots.

Order this beverage in small, medium, or large, or buy the tea bags so you can make it at home.  

Barista HQ Tip: You can also get iced keto friendly tea options, and ordering an iced green tea unsweetened will give you a refreshing and low carb drink.

10. Chamomile Fields Herbal Infusion Tea 

Dunkin Chamomile Fields and Blueberry Tea

If you can imagine a blend of orange peel, chamomile flowers, and lemongrass together in hot water, then you can imagine this drink.

It's caffeine-free, and it has 0 grams of net carbs, sugars, and fats.

Again, you can buy this tea in pyramid-shaped tea bags so you can have this keto drink on the go as part of a versatile low carb diet.  

11. Bold Breakfast Black Tea 

Dunkin Bold Breakfast Black Tea

Dunkin’s bold breakfast black tea is one of their best-selling teas on the menu, and is also one of the best low carb drinks. It’s delicious and has a full-bodied flavor.

This beverage is available in a caffeinated and decaffeinated versions.

For a caffeinated cup of this tea, there's about 90 mg in a small 10 fl oz cup.  

12. Hibiscus Kiss Herbal Infusion 

Dunkin Donuts Hibiscus Kiss Tea

This is a caffeine-free, herbal infusion with notes of hibiscus, herbs, and natural berry flavors. It delivers a bright and juicy red color, and its flavors blend together with every sip.

This drink is delicious hot or cold, and it's completely sugar free because it's iced tea unsweetened by any additions. It's available in a small, medium, or large. 

13. Unsweetened Iced Tea 

Dunkin Donuts Unsweetened Iced Tea

You’ll be pleased to hear that Dunkin iced teas are free from added sugars and fats. Also, there are only about 4 grams of carbs in their selection of teas (medium over the range of sizes). 

These beverages come in sizes small, medium, and large, and they’re a great way to get some caffeine intake without going overboard. 

Barista HQ Tip: You can keep your iced tea unsweetened and still add sugar-free flavor shots of raspberry or blueberry to any black or green iced tea- this will give you a ton of flavor.

14. Keto Latte’s 

Dunkin Donuts Keto Friendly Iced Latte

If you order a latte with coconut milk or cream (not whipped cream!), you are well within your keto-friendly diet. Both options are only about a gram in sugar, and it has a medium of 3 grams of net carbs (average overall sizes).

On the other hand, there's a medium of 4.5 grams of fat in a keto latte, so keep it to a treat day beverage. 

Toasted almond lattes are really popular right now, and all you need to do is ask for a toasted almond latte flavor shot in the drink. 
Barista HQ Tip: Want your keto latte a bit sweeter? Add in some flavor shots or flavor swirls to make your coffee drinks sweet, but keep it keto at Dunkin.

Dunkin Donuts Vs Starbucks Keto Drinks

There is a range of keto-friendly drinks available at Dunkin Donuts and Starbucks, but which are the best on the market?

Personal preference is king when it comes to deciding for yourself, but there are a few other metrics I measured these titans of coffee against.


I'm a coffee lover on a budget, so of course the price of my caffeine fix is important to me. Who comes out on top?

To break down the cost difference with a few examples (with no extras or customisations):

My budget coffee of choice, drip coffee at Starbucks will typically cost you between $1.95 and $2.65 but will cost $1.59-$2.09 at Dunkin. 

Cold brew is another fave of mine that costs $2.95-$3.75 at Starbucks and $2.59-$3.09 at Dunkin - it's not looking good for Starbucks.

In terms of milky drinks, my fave latte would cost anywhere from $2.95-$4.15 at Starbucks but will cost only $2.69-$3.69 at a Dunkin Donuts.

That's not to mention the wide range of offers and membership rewards both companies offer through their reward programs.

In other words, Dunkin's prices have risen over the years but they still come up cheaper than Starbucks.

Cup Size

Price is still pretty relevant here, since I always try to get the most bang for my buck when getting my daily caffeine fix. 

This means I want to get as much coffee as I can for a good price - how do Starbucks and Dunkin's cup sizes compare?

Starbucks' cup sizes are:

  • Short - 8 ounces
  • Tall - 12 ounces 
  • Grande - 16 ounces
  • Venti (Hot) - 20 ounces 
  • Venti (Cold) - 24 ounces 
  • Trenta - 31 ounces 

On the other hand, Dunkin's cup sizes are:

  • Small (Hot) - 10 ounces
  • Small (Cold) - 16 ounces
  • Medium (Hot) - 14 ounces
  • Medium (Cold) - 24 ounces
  • Large (Hot) - 20 ounces 
  • Large (Cold) - 32 ounces 
  • Extra-Large (Hot) - 24 ounces 
In other words, Dunkin' has the most bang for your buck in terms of value per dollar, especially when it comes to cold drinks. 


With the keto diet becoming more popular in recent years, the food and drink options have really skyrocketed.

But is Starbucks or Dunkin' better when it comes to the variety in their keto options?

Starbucks is well-known for its abundant regular menu and exciting rotation of seasonal offerings, along with their incredible cult following of secret menu drink crafters.
