A doubleshot on ice is shaken espresso: 2 or 3 fresh shots, 2 tsp simple syrup, a cup of ice, shaken hard for 15 seconds, strained over fresh ice, finished with a splash of milk. The shake is not showmanship; it chills, dilutes, and aerates the espresso into something smoother than any poured iced latte. Two 1oz shots carry about 126mg of caffeine and three about 189mg, using USDA's espresso figure of roughly 63mg per shot (USDA FoodData Central). Home version of a menu drink, not a chain formula.
The build
| Ingredient | Amount | Replaces |
|---|---|---|
| Espresso, fresh and hot | 2 to 3 shots | Signature espresso shots |
| Simple syrup | 2 tsp | Classic syrup pumps |
| Ice for shaking | 1 cup | Shaker ice |
| Fresh ice for serving | 1/2 cup | Cup ice |
| Milk or cream | 1 to 2 oz splash | Milk |
How to make it
- Pull the shots and pour them hot straight into a shaker loaded with ice. Hot espresso plus violent chilling is what builds the foam.
- Add the simple syrup and shake hard for 15 seconds.
- Strain into a glass over fresh ice so you are not drinking the shattered shaker ice.
- Top with a splash of milk.
Why shaking beats stirring, chemically
Shaking hot espresso with ice does three things at once: it drops the temperature fast enough to preserve aromatics that slow cooling destroys, it melts a controlled amount of water into the shot, and it whips air into the crema proteins to make a foam cap. The same shots poured over ice taste sharper and thinner. This is also the mechanism behind the shakerato, the Italian original; our shakerato guide covers that variant.
Do not confuse it with the canned Doubleshot
Starbucks sells a canned Doubleshot in stores, and it is a different product entirely: a small, milky, pre-mixed can rather than fresh shaken shots. The numbers for that can live on our Doubleshot caffeine page. The made-to-order doubleshot on ice is famous mostly for being one of the cheapest high-caffeine orders on the menu, and the home version costs pocket change per glass.
Caffeine, with sources
Two 1oz shots put the drink near 126mg, three near 189mg, per the USDA espresso figure of 212mg per 100g, about 63mg per 1oz shot (USDA). The FDA cites 400 milligrams a day as an amount not generally associated with dangerous effects for healthy adults (FDA). Everything on this page is information, not health advice.
Two tools, no syrups needed
A cocktail shaker and an espresso scale cover this drink forever; simple syrup is sugar and water simmered at 1:1.

FAQ
What is in a Starbucks doubleshot on ice? Fresh espresso shots shaken with ice and classic syrup, strained over ice with a splash of milk. The home version is identical: shots, simple syrup, a hard 15-second shake, milk to finish.
How much caffeine is in a doubleshot on ice made at home? About 126mg with two 1oz shots or 189mg with three, using USDA's roughly 63mg per shot espresso figure.
Why shake the espresso instead of just pouring it over ice? Shaking chills the shot fast enough to keep its aromatics, adds controlled dilution, and whips the crema into a foam cap. Poured shots taste sharper and flatter by comparison.
