Since going keto, I’ve spent more time than I expected scanning Dunkin menus for drinks I can order without turning the whole thing into a carb-heavy mistake. At first the options felt limited, so I started keeping a shortlist of drinks I actually order.
These are the Dunkin drinks I come back to when I still want Dunkin, just without a bunch of extra carbs.
14 Dunkin Donut keto-friendly drinks (Best options for your diet)
1. Drip Coffee
Dunkin’s drip coffee is the easiest place to start. Ordered plain, it stays essentially carb free and sugar free.
That means no whole milk, skim milk, or sugar. Once I keep it black, it stays simple and matches the way I usually order coffee.
Dunkin’s arabica beans give the coffee a familiar roasty taste, and that fuller flavor is part of why I usually don’t need anything added.
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.
Once I started paying closer attention to keto labels, I realized how many of my usual coffee orders depended on milk and syrup more than I thought.
For home coffee, the Bulletproof ground coffee is the one I reach for most often, usually with MCT oil too. I keep it for days when I want a cup that feels richer than my usual black coffee.
Barista HQ Tip: You can also add almond milk or oat milk as a dairy free milk alternative.

2. Americano
An Americano is just espresso and hot water, so it was an easy addition to this list of keto Dunkin 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
If I want something colder, I usually reach for an unsweetened iced coffee. I leave out milk and sugar, and it still fits the kind of keto-style order I want.
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
I also like an iced coffee Americano on hot days or before a workout, mainly because it feels sharper and lighter than a milky drink.
Nutritionally, it’s basically the same idea as a hot Americano, though the ice can soften the bitterness a little.
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
If cold brew is already your thing, Dunkin’s Nitro cold brew is worth looking at. Plain, it’s listed with 0 grams of 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.
What I notice first is that it tastes smoother and a little less acidic than regular coffee, with a natural sweetness that makes it easier to drink black.
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
When I’m in a hurry and want caffeine fast, I usually just order 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
The tea menu is where I like to experiment a little, especially with sugar-free flavor shots. Bold black breakfast tea is a straightforward place to do that.
It has blueberry, raspberry, and coconut notes, and the flavor stays clean enough that it doesn’t feel heavy. It’s also listed as having 0 grams of net carbs, sugars, and fats.
8. Cool Mint Herbal Infusion Tea
Dunkin’s mint herbal infusion is the one I pick when I want something cooler and lighter. The peppermint and herbs make the first sip feel crisp.
It’s caffeine-free, which is part of why I reach for it when I want something soothing rather than another jolt.
You can also buy Dunkin’s tea sachets in stores or grocery stores, which makes it easy to keep around at work or at home.
9. Harmony Leaf Green Tea
Harmony Leaf green tea gives me a little more caffeine without feeling too heavy. It’s listed at 70 mg, and I usually keep it simple or add strawberry or raspberry flavor shots when I want a little fruitiness.
You can order it in a small, medium, or large, or buy the tea bags and 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
If you brew orange peel, chamomile flowers, and lemongrass together, you get a pretty good idea of this tea’s flavor.
It’s caffeine-free, and it has 0 grams of net carbs, sugars, and fats.
It also comes in pyramid-shaped tea bags, which is handy if you want to keep a low-carb drink with you on the go.
11. Bold Breakfast Black Tea
Dunkin’s bold breakfast black tea is one of the menu staples I keep coming back to because the flavor is full and straightforward without feeling flat.
It comes in 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
This herbal infusion is caffeine-free and has hibiscus, herbs, and natural berry flavors. The first sip feels bright, and the red color matches that juicy fruit note.
I like this one both hot and cold, and as long as it’s unsweetened, it stays sugar free. It comes in small, medium, and large sizes.
13. 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).
Those sizes make it easy for me to keep caffeine intake moderate 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
If I want something creamier, I’ll order a latte with coconut milk or cream and skip whipped cream. That keeps the drink much lighter in sugar than a standard latte.
It’s still richer than a black coffee, though, so I usually treat it as an occasional order rather than an everyday one.
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 are plenty of keto-friendly drinks at Dunkin and Starbucks, but the better one depends on what I usually want that day.
For me, personal preference still comes first, but price, cup size, and variety are the other things I usually check.
Price
I’m pretty budget-minded with coffee, so cost matters more than I used to admit.
Here’s a quick look at the prices for a few plain drinks, with no extras or customisations:
My budget coffee of choice, drip coffee at Starbucks, typically costs between $1.95 and $2.65, while Dunkin is usually $1.59 to $2.09.
Cold brew is another one I order a lot, and Dunkin usually comes in a little lower at $2.59 to $3.09 compared with Starbucks at $2.95 to $3.75.
For milky drinks, a latte is also usually a bit easier on the wallet at Dunkin, where it runs about $2.69 to $3.69 versus $2.95 to $4.15 at Starbucks.
Both chains also have rewards programs and occasional offers, which can change the value quite a bit.
In other words, Dunkin’s prices have risen over the years but they still come up cheaper than Starbucks.
Cup Size
Price still matters to me because I like my daily coffee to feel like a small purchase, not a luxury.
That’s why cup size matters too, especially when I’m trying to get enough coffee without overspending.
Starbucks’ cup sizes are:
On the other hand, Dunkin’s cup sizes are:
In other words, Dunkin’ has the most bang for your buck in terms of value per dollar, especially when it comes to cold drinks.
Variety
Keto drinks have become easier to find in recent years, and menu variety has definitely improved.
The real question is whether Starbucks or Dunkin gives you more keto options you’d actually order.
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.
FAQs
Can you drink Dunkin Donuts drinks when you are on a keto diet?
I can still make Dunkin work on keto. The drinks above are the ones I usually narrow it down to, depending on how much coffee, tea, or creaminess I want.
What are the sugar-free flavors at Dunkin Donuts?
Dunkin also offers a range of flavors and flavor swirls, including blueberry, coconut, French vanilla, hazelnut, raspberry, and toasted almond.
How many carbs are in a small french vanilla iced coffee from Dunkin Donuts?
A traditional French vanilla iced coffee with milk is far from the order I keep if I want to stay keto, so I only think of it after reworking the drink. A coconut milk latte with a sugar-free sweetener is the simpler swap.
What can I eat at Dunkin Donuts that is keto-friendly?
Sadly, there aren’t many low-carb Dunkin food options that are keto-friendly. However, there’s a small low-carb bag of snacking bacon. Each serving has 8 pieces, and they contain 190 calories, 12g of fat, 10g of carbs, 9g of sugar, and 10g of protein.
Conclusion
Once I narrowed it down, it became easier to build an order around whichever drink fits my routine.
