How to Make Dalgona Coffee (Whipped Coffee)
Dalgona coffee, or whipped coffee, is made by whisking equal parts instant coffee, sugar and hot water (a 1:1:1 ratio, typically 2 tablespoons of each) into a thick caramel-coloured foam, then spooning it over a glass of hot or iced milk. Instant coffee is essential: its soluble compounds let the foam whip up, where fresh espresso simply will not hold.
- Ratio: 1:1:1, equal parts instant coffee, sugar and hot water
- Classic base: 2 tablespoons of each, for two cups
- Coffee: instant only, no espresso or ground coffee
- Whisking: 3 to 5 minutes by hand, 2 to 4 minutes with a mixer
- Target result: a caramel-coloured foam that holds soft peaks
- Serving: over about 200 ml of milk per cup, hot or iced
What dalgona coffee is
Dalgona coffee is a whipped coffee that went viral in early 2020, during periods of social distancing. It takes its name from dalgona, an old Korean street sweet with a honeycomb-toffee texture, which the coffee foam echoes in colour and sweetness. The recipe took off in South Korea after appearing on television, then spread across social media worldwide.
Technically, it is the opposite of a flat white. Here you do not texture the milk, you texture the coffee itself. You whisk instant coffee, sugar and hot water into an airy, caramel-coloured cream, then spoon it over a glass of milk. The visual effect, two clearly separate layers, is part of the drink's appeal.
The most surprising part is the role of instant coffee. Far from being a shortcut, it is here a deliberate choice for its chemistry. Instant coffee, freeze-dried or spray-dried, contains soluble compounds and oils that can trap air and stabilise a foam. Fresh espresso or ground coffee, by contrast, will not whip up: they lack those compounds in the form required.
Ingredients and equipment
The strength of dalgona is its simplicity. Three storecupboard ingredients and a little elbow grease are all it takes.
- 2 tablespoons instant coffee (freeze-dried or spray-dried, powder or granules)
- 2 tablespoons sugar (sugar is not only about taste: it thickens the mix and stabilises the foam)
- 2 tablespoons hot water to dissolve the powder fully
- About 200 ml milk per cup, hot or iced (plant-based milk works too)
- A bowl, a hand whisk or an electric mixer, and a glass
The step-by-step method
It all comes down to the whisking: it is the agitation that lifts the foam. Keep the 1:1:1 ratio and be patient.
- Combine the three ingredients in equal parts. Put 2 tablespoons of instant coffee, 2 tablespoons of sugar and 2 tablespoons of hot water in a bowl. This 1:1:1 ratio is the key: do not cut the sugar, which helps the foam hold.
- Whip to a caramel foam. Whip non-stop. Plan on 3 to 5 minutes by hand with a whisk, or 2 to 4 minutes with an electric mixer on high speed. The mix turns from a dark brown liquid into a pale, caramel-coloured cream that holds soft peaks. By hand, expect several hundred continuous strokes.
- Prepare the milk. Meanwhile, fill each glass with about 200 ml of milk. For a hot version, warm the milk; for an iced version, add ice cubes. Both work well.
- Spoon on the foam. Spoon the coffee foam generously over the milk. It should float in a thick caramel-coloured layer, clearly separate from the milk below.
- Stir and enjoy. Serve as is to admire the two layers, then stir the foam into the milk with a spoon or straw before drinking. You get a smooth, sweet, even coffee.
Whisk, mixer or frother: the table
Dalgona whips up with several tools. The choice affects time and effort, but not the ratio, which stays 1:1:1. The figures below are common ballpark ranges.
| Method | Time | Effort | Result |
|---|---|---|---|
| Hand whisk | 3 to 5 min | high, several hundred strokes | firm foam, full control |
| Electric mixer | 2 to 4 min | low | fast, even foam |
| Milk frother | variable, small batches | low | handy but a narrow bowl helps |
In short: the electric mixer is fastest and least tiring. A hand whisk is still very effective if you keep up the pace. A frother will do in a pinch, as long as you work in a narrow container to gather the mix.
Frequently asked questions about dalgona coffee
Can you make dalgona with espresso?
No, not reliably. Dalgona coffee whips up thanks to instant coffee, freeze-dried or spray-dried, whose soluble compounds and oils trap air into a stable foam. Fresh espresso or ground coffee do not contain those compounds in the right form, so they will not whip into foam no matter how long you beat them. Instant coffee is essential.
What is the ratio for dalgona coffee?
Dalgona uses a 1:1:1 ratio, equal parts instant coffee, sugar and hot water. The classic base is 2 tablespoons of each, which gives enough foam for two cups or one generous cup. You then spoon the foam over about 200 ml of milk per cup.
How long do you whisk dalgona coffee?
Plan on about 3 to 5 minutes by hand with a whisk, or 2 to 4 minutes with an electric mixer on high speed. The foam is ready when it turns from a dark liquid into a pale, caramel-coloured cream that holds soft peaks. By hand, expect several hundred continuous strokes.
Why is my dalgona not whipping into foam?
The most common reason is using coffee that is not instant: espresso, ground or filter coffee will not whip. Also check the 1:1:1 ratio without cutting the sugar, which stabilises the foam, and use hot water to dissolve the powder fully. Too little whisking or too wide a bowl can also stop the foam from forming.
