A medium 24 oz Baskin Robbins Cappuccino Blast has about 234mg of caffeine, according to Caffeine Informer, which got the number directly from Baskin Robbins customer service. That works out to roughly 9.75mg per fluid ounce, which puts a small at around 156mg and a large at around 312mg. For a drink most people order as a milkshake, that is a legitimate dose of caffeine. A large lands close to a triple shot of espresso and change.
The milkshake that outcaffeinates your latte
The Cappuccino Blast is easy to underestimate because it arrives with whipped cream and a dome lid. It reads as dessert. But the base is brewed coffee blended with ice cream and ice, and the coffee is doing real work in there. At 234mg, the medium carries well over what Caffeine Informer lists for a standard 8 oz cup of brewed coffee, which averages 163mg. Order a large and you are drinking the caffeine of nearly two full cups of coffee disguised as a milkshake.
Two caveats worth knowing before you rely on these numbers. First, the caffeine figure comes from Caffeine Informer's correspondence with Baskin Robbins customer service, not from a published lab test, and the company itself said the amount can vary depending on add-ins and preparation. Second, what goes in the blender matters a little. Baskin Robbins told Caffeine Informer the caffeine amount can shift with add-ins and preparation, and a coffee-flavored ice cream in the mix will carry a bit more than vanilla. The brewed coffee base is still where almost all of the caffeine comes from, so treat flavor choice as rounding error, not a strategy.
The Classic Cappuccino, Mocha, and Caramel versions all share the same coffee base, so caffeine stays roughly consistent across the flavor lineup. What changes more between flavors is sugar, and none of the options are shy about it.
Cappuccino Blast caffeine, calories, and sugar by size
Caffeine per size is scaled from the verified 24 oz figure at 9.75mg per ounce. Calories and sugar are for the Cappuccino Blast with whipped cream, per FastFoodNutrition's Baskin Robbins data.
| Size | Volume | Caffeine | Calories | Sugar |
|---|---|---|---|---|
| Small | 16 oz | ~156mg (est.) | 310 | 38g |
| Medium | 24 oz | 234mg | 470 | 57g |
| Large | 32 oz | ~312mg (est.) | 600 | 74g |
The sugar column deserves a look on its way past. A medium carries 57g of sugar and a large hits 74g. Between the caffeine and the sugar, a large Cappuccino Blast is not an afternoon treat so much as a full commitment.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. How caffeine affects you depends on your own tolerance and health, so treat these numbers as information, not advice.
A large on its own puts you at 312mg, or about three quarters of that daily reference point. If you had a regular coffee in the morning and grab a large Blast at 3pm, you are past 400mg and probably staring at the ceiling at midnight. The small is the sane play if you already drink coffee: real caffeine, dessert experience, and you stay well inside the daily math.

How it compares to other blended and bottled coffee
Blended and dessert-style coffee drinks are all over the map on caffeine, which is exactly why it pays to check before ordering. Smoothie King's coffee smoothies play in a similar blended lane with very different numbers, covered in our Smoothie King caffeine guide. On the grab-and-go side, the bottled Starbucks Frappuccino that lives in gas station coolers carries far less caffeine than its size suggests, broken down in our bottled Frappuccino caffeine guide. And if you want one place to compare every chain and canned drink we have tested the numbers on, the caffeine database is the master list.
FAQ
Does the Cappuccino Blast have more caffeine than regular coffee? Ounce for ounce, no. Brewed coffee averages around 20mg per ounce while the Blast is about 9.75mg per ounce. But the serving sizes are huge, so a 24 oz medium at 234mg still beats a standard 8 oz cup of brewed coffee at 163mg by a wide margin.
Do the Mocha and Caramel versions have different caffeine than the original? Not meaningfully. All flavors share the same brewed coffee base, so caffeine stays roughly the same across Classic Cappuccino, Mocha, and Caramel. Baskin Robbins notes the exact amount can vary with add-ins and preparation, but flavor choice is not the deciding factor.
Is there a decaf or low-caffeine Cappuccino Blast? There is no standard decaf version on the menu. Your lower-caffeine move is ordering the 16 oz small, which cuts the dose to roughly 156mg, still more than a typical cup of coffee but well under the medium and large.
