The Dunkin’ Tiramisu Protein Latte is the functional member of Dunkin’s four-drink tiramisu lineup for fall 2026 — the one you can order on a morning when you want something seasonal without abandoning your protein goals. It’s straightforward: espresso and protein milk with a tiramisu swirl. No marshmallow cold foam, no hot chocolate powder dusting, no shaking technique. Just a clean latte built on a high-protein milk base.
It launched August 19 alongside the other three tiramisu drinks and Dunkin’s protein milk, which had already been available since January 2026. The pairing is deliberate — the protein milk addition turned an ordinary tiramisu latte into a nutritional talking point. A medium lands at 17 grams of protein, which is more than many dedicated protein shakes.
Making it at home is simple once the tiramisu syrup is done. If you’ve already made the syrup for the Cloud Latte or Shakin’ Espresso, you already have what you need — the syrup is identical across all four drinks.
What Makes This Different from the Other Three
The tiramisu lineup has four drinks built on the same swirl. The differences are the milk base and the format:
| Tiramisu Protein Latte | Tiramisu Cloud Latte | Tiramisu Shakin’ Espresso | Tiramisu Marshmallow Matcha | |
|---|---|---|---|---|
| Base | Protein milk | Whole milk | Oatmilk (shaken) | Whole milk |
| Espresso | Yes | Yes | Yes | No (matcha) |
| Foam | None | Marshmallow cold foam | Airy shaken froth | Marshmallow cold foam |
| Topping | None | Hot chocolate powder | None | Hot chocolate powder |
| Temperature | Hot or iced | Hot or iced | Iced only | Iced only |
| Protein (medium) | ~17g | ~5g | ~3g | ~5g |
| Best for | Protein goal day | Dessert treat | All-day coffee | Non-coffee drinkers |
The Protein Latte is the cleanest build in the lineup. No topping to assemble, no technique beyond pulling shots and pouring milk. Its single differentiator is the milk — and that’s also where all the protein comes from.
Dunkin’s Protein Milk: What It Actually Is
Dunkin’ launched its protein milk in January 2026 as part of a broader push into high-protein menu additions. The milk is ultra-filtered — a category that includes fairlife, Lactaid 2% Protein Milk, and several other brands — which means it’s been filtered to remove some of the water and concentrate the protein and fat while reducing some of the lactose.
The result is milk that tastes like milk (not a protein shake) but delivers meaningfully more protein per ounce. Standard whole milk has about 8 grams of protein per cup. Dunkin’s protein milk delivers enough protein that a medium drink — the milk volume is roughly 10–12 oz — hits 17 grams.
It also has a slightly creamier texture than standard milk, which is a genuine benefit in a hot latte. Ultra-filtered milk steams and froths identically to regular milk, so hot and iced builds both work.
One honest caveat: some reviewers have noted a faint aftertaste from ultra-filtered protein milk that isn’t present in regular milk — a mildly mineral or “functional” quality that’s common to this category of milk. At Dunkin’, at least one reviewer flagged it as slightly off-putting. Fairlife tends to be one of the better-tasting ultra-filtered milks in this respect; if the aftertaste bothers you, the 1-tablespoon syrup reduction tip below amplifies the espresso character relative to the milk, which helps.
The Right Home Substitute
Fairlife 2% ultra-filtered milk is the closest widely available match to what Dunkin’ is serving. It delivers 13 grams of protein per cup (vs. 8g for standard 2%), filters out most of the lactose, and has a slightly richer texture. For a 10-oz latte pour, that puts the home version at about 16 grams of protein from the milk — just under Dunkin’s 17g medium, with the remaining gram or two coming from the espresso and trace amounts in the syrup.
Other options if fairlife isn’t available: any brand of ultra-filtered milk (Organic Valley Fuel, store-brand ultra-filtered); or stir 10g of unflavored whey protein powder into regular whole milk before using — the protein lands in the same range, though the texture is slightly thinner.
The mascarpone in the tiramisu syrup adds negligible protein (under 1 gram per drink from the 2-tablespoon portion of a batch). What it does add is fat and richness that the regular Dunkin’ swirl doesn’t have — the real mascarpone makes the drink taste notably more like actual tiramisu, regardless of the milk base.
No Foam. No Dusting. Why That’s the Point.
The Cloud Latte and Marshmallow Matcha are dessert drinks — the marshmallow cold foam and hot chocolate powder dusting are as much about the experience as the flavor. The Protein Latte deliberately strips those elements out. No foam to make, no powder to dust, no topping to balance.
This keeps the calorie count lower than the topped drinks (the marshmallow foam alone adds about 90 calories to the Cloud Latte), but more importantly it keeps the drink honest. What you’re drinking is espresso and protein milk with a tiramisu swirl. The swirl carries the tiramisu character; everything else is coffee and protein.
If you want to add the hot chocolate powder dusting at home, nothing stops you — tap a pinch through a fine-mesh strainer over the surface. But it’s not part of the Dunkin’ build, and the drink doesn’t need it. The tiramisu swirl has a subtle cocoa note already from the cocoa powder in the syrup.
Is 17g of Protein Actually Useful in a Coffee Drink?
For context: a large egg has 6g of protein. A 6-oz container of Greek yogurt has roughly 17g. A standard 25g scoop of whey protein powder has 20–25g. So 17g from a coffee drink is meaningful — not a replacement for a protein meal, but a genuine contribution.
The practical case for the Tiramisu Protein Latte is timing: if you’re already stopping at Dunkin’ for a morning coffee, swapping from a standard latte to the protein version adds 9 grams of protein to your day (17g vs. ~8g for a standard milk latte) without changing the flavor profile of the drink in any meaningful way. For someone hitting 130–160g daily protein targets, that’s a worthwhile upgrade.
The home version with fairlife 2% costs about $1.10 per drink — vs. $5+ at Dunkin’ — and the syrup batch makes the economics of the mascarpone upgrade trivial across 6–8 drinks.
Hot Version Notes
The Tiramisu Protein Latte is one of only two drinks in the fall 2026 tiramisu lineup available hot (the Cloud Latte is the other). The hot build is simple: steam or froth 10 oz of ultra-filtered milk to about 150°F, stir the tiramisu syrup into the hot espresso shots, and pour the milk in. Ultra-filtered milk steams identically to regular milk — same microfoam behavior, same pour, same mouthfeel.
On a hot latte, the mascarpone in the syrup adds a subtle richness that reads like a flavored latte with slightly more body. No foam, no topping — the tiramisu character comes entirely from the swirl and espresso combination. On cold mornings before a workout, this is the version to make.
The Full Dunkin’ Fall 2026 Tiramisu Lineup
All four drinks share the same tiramisu swirl and launched August 19, 2026. The syrup in this recipe works across all four.
- Tiramisu Protein Latte — espresso + protein milk + swirl; hot or iced; 17g protein (this recipe)
- Tiramisu Cloud Latte — espresso + whole milk + swirl, marshmallow cold foam, hot chocolate powder; hot or iced
- Tiramisu Shakin’ Espresso — double espresso shaken with swirl and oatmilk; iced only
- Tiramisu Marshmallow Matcha — matcha + whole milk + swirl, marshmallow cold foam, hot chocolate powder; no espresso; iced only
The tiramisu swirl can also be added to any hot or cold Dunkin’ drink at the counter.
Variations
Protein boost upgrade. Stir 10g of unflavored collagen powder into your ultra-filtered milk before building the drink. Collagen dissolves cold without clumping, adds 9 grams of protein, and has essentially no flavor. Combined with the fairlife base, this gets the home version to 25 grams of protein — a meaningful difference.
Cold brew base. Substitute 4 oz of Dunkin’-style cold brew concentrate for the espresso shots. Cold brew has more body and slightly more caffeine than hot-pulled espresso, and its lower acidity makes the tiramisu swirl’s cream notes come through more prominently. Use 4 oz concentrate + 6 oz ultra-filtered milk over ice.
Add the foam. If you want the Cloud Latte experience with the protein milk base, nothing stops you — make the marshmallow cold foam (3 tbsp heavy cream + 1 tbsp milk + 1 tbsp marshmallow fluff, frothed 20 seconds) and pour it over the assembled latte. The protein milk base doesn’t interfere with the foam.
Alcohol version. Classic tiramisu uses marsala wine or dark rum. Add 1/2 oz (1 tablespoon) of coffee liqueur to the espresso-syrup blend before chilling or building. The alcohol doesn’t affect protein content.
