How We Define "Keto Friendly" at Dunkin'
The methodology behind the threshold and rankings on this page.
Threshold: 12g net carbs or less
This page lists drinks where net carbs at the smallest available size are 12g or below. Stricter keto approaches may target 5g or fewer — use the 0–3g filter above for the most restrictive options. The reference size varies by drink (Small, Medium, or the first listed size in Dunkin's data).
Net carbs = total carbs minus dietary fibre
Dietary fibre is subtracted from total carbohydrates because it is not absorbed the same way. This is the standard keto tracking approach. Values are shown at the default variant — the first dairy and sweetener combination listed in Dunkin's official nutrition data.
Sweetener choice significantly affects net carbs
Many Dunkin' drinks are available with sugar-free sweetener, which can reduce net carbs by 10–20g compared to the standard recipe. Drinks marked "sugar-free option" on this page have a sweetener variable — click through to see the full breakdown by sweetener and dairy choice.
Dairy choice has a smaller impact at Dunkin'
Unlike some chains, switching dairy options at Dunkin' typically changes net carbs by only 2–5g. Sweetener choice has a far greater impact. The individual drink pages show calorie and carb breakdowns across all available dairy and sweetener combinations.

3 drinksHow to Order Keto at Dunkin'
Practical strategies that work across the Dunkin' menu — most can be applied at the counter or on the app.
Always ask for sugar-free sweetener
This is the single most impactful change at Dunkin'. Most flavoured coffee drinks default to a sugar-based sweetener that adds 15–25g of carbs. Requesting the sugar-free version removes most of this while keeping the same flavour profile.
Order the smallest size
Carbs scale with size at Dunkin'. A Small is often the only size that stays within keto range. The drink pages on this site show the net carb count at every available size — always check before sizing up.
Stick to black coffee or plain espresso
Dunkin' drip coffee and straight espresso shots contain essentially zero net carbs at any size. These are the most reliably keto options on the menu regardless of customisation. Adding cream (not milk) keeps carbs near zero.
Avoid flavoured swirl syrups
Dunkin's "swirl" syrups — such as caramel, mocha, and French vanilla swirl — are sugar-based and add significantly more carbs than the standard flavour shots. Flavour shots (unsweetened) are a lower-carb alternative and are available on most drinks.

Dunkin' Keto Friendly Drinks — FAQ
Common questions about ordering keto at Dunkin' and how net carbs are calculated.
The most keto-friendly Dunkin' drinks are plain black coffee, straight espresso, and Americano — all of which contain essentially zero net carbs at any size. If you want a flavoured drink, ordering a coffee with sugar-free flavour shots and cream (rather than milk) can keep net carbs under 3g. Avoid swirl syrups, which are sugar-based and significantly increase carbs.
Dunkin' offers two types of flavouring. Flavour shots (such as French Vanilla, Hazelnut, Toasted Almond) are unsweetened and add essentially no carbs. Swirl syrups (such as Caramel Swirl, Mocha Swirl) are sugar-based and can add 10–20g of carbs per serving. For keto, always choose flavour shots or ask for sugar-free syrup — never the swirl.
Net carbs on this page are calculated as total carbohydrates minus dietary fibre, using values from Dunkin's published nutrition data. Values are shown at the smallest available size using the first (default) variant. Click through to any drink page for the full breakdown across all sizes, dairy options, and sweetener types.
Dairy choice has a relatively small effect on net carbs at Dunkin' — typically 2–5g difference between dairy options at the same size. Sweetener choice has a much larger impact. If keto compliance matters, prioritise switching sweetener over switching milk. Each drink page shows the full calorie and carb breakdown across both dimensions.
Plain Dunkin' cold brew — without added milk, cream, or sweetener — is very low in net carbs at any size. Adding cream keeps it keto-compatible. Adding standard milk or swirl syrups will raise carbs significantly. Check the individual cold brew drink page for exact values across all customisation options.
