Dalgona coffee is instant coffee, sugar, and hot water whipped in equal parts until it turns into a thick, stiff-peaked foam, then spooned over milk. It gets its name from its visual resemblance to dalgona, a Korean sugar-and-baking-soda honeycomb candy — the drink itself has no candy in it. It went viral worldwide in 2020 after a video of Korean actor Jung Il Woo trying the drink at a Macau café spread on TikTok and YouTube.
This guide covers the real ratio, three different ways to whip it (with an honest comparison of which one actually works), and a full nutrition and caffeine breakdown.
What Is Dalgona Coffee?
It’s whipped instant coffee — equal parts instant coffee, sugar, and boiling water, whisked until it turns pale and holds stiff peaks like meringue, then dolloped over hot or cold milk. Instant coffee is essential here: it contains soluble compounds that trap air and hold a stable foam structure. Ground or brewed coffee has no such structure and will not whip, no matter how long you try.
How to Make Dalgona Coffee
The ratio is always 1:1:1 — equal parts by volume. Scale it up or down as needed.
Ingredients (per serving)
- 2 tablespoons instant coffee
- 2 tablespoons granulated sugar
- 2 tablespoons boiling water
- 3/4 to 1 cup milk of choice, hot or cold
Steps
- Combine the instant coffee, sugar, and boiling water in a bowl.
- Whip using your method of choice (see the comparison below) until the mixture turns pale tan and holds stiff, glossy peaks.
- Fill a glass with milk — hot for a warm drink, or cold with ice for iced dalgona coffee.
- Spoon the whipped coffee foam on top. Stir before drinking to combine.
Whisk vs. Mixer vs. Milk Frother: Which Actually Works?
Most recipes list a hand whisk, an electric hand/stand mixer, or a milk frother as interchangeable options. In practice they are not equally reliable, and the honest answer depends on what you own:
| Method | Time | Result |
|---|---|---|
| Hand whisk | 8–15 minutes | Reliable, but a genuine arm workout |
| Hand or stand mixer | 2–3 minutes | Most reliable and fastest — the favorite method across recipe testers |
| Powerful milk frother | ~1–several minutes | Can work, but inconsistent — a weak wand may never reach stiff peaks |
| Immersion blender / regular blender | — | Not recommended — built for a thin liquid, not for building foam structure in a thick paste |
If you already own a milk frother, it’s worth trying first since it’s the fastest option if it works — but a single-wire handheld frother is built to aerate thin milk, not to whip a thick coffee-sugar-water paste into stiff peaks, so results vary a lot by how powerful your unit is. See our guide to frothing milk for how these tools are meant to be used — a hand or stand mixer is the more dependable choice for dalgona specifically.
Dalgona Coffee Caffeine and Nutrition
Caffeine varies by brand of instant coffee, but a reasonable estimate for the standard 2-tablespoon recipe lands in the 90–180mg range.
| Ingredient / Serving | Caffeine | Notes |
|---|---|---|
| Instant coffee, 1 tsp (USDA estimate) | ~28mg | 2 tbsp = 6 tsp ≈ 170mg by this estimate |
| Instant coffee, typical commercial brands | 30–90mg per tbsp | Varies significantly by brand — check your label |
| Full recipe, realistic range | ~90–180mg | Depends on the brand of instant coffee used |
For comparison against a regular coffee drink, see our breakdown of how much caffeine is in a latte. If you want the flavor without the caffeine, use a decaf instant coffee — see our best decaf coffee picks.
Iced vs. Hot Dalgona Coffee
The whipped foam itself is identical either way — the only difference is what’s underneath it. Pour it over hot milk for a traditional warm drink, or over cold milk and ice for an iced version, which has become the more popular way to serve it. For general iced coffee technique, see our guide to how to make iced coffee.
Variations
- Matcha dalgona: whip matcha powder, sugar, and hot water the same way instead of instant coffee — same technique, different base.
- Sugar-free: substitute stevia or monk fruit sweetener, though the foam may be slightly less stable since sugar helps structure the peaks — test in a small batch first.
- Decaf dalgona: use a decaf instant coffee brand — the whipping process is unaffected.
- Dairy-free: oat or almond milk work fine as the base — the foam sits on top regardless of milk type.
Frequently Asked Questions About Dalgona Coffee
Yes. Instant coffee contains soluble compounds that trap air and whip into a stable foam. Ground or brewed coffee has no such structure and will not whip into peaks.
A realistic range for the standard recipe is about 90 to 180mg, depending on the brand of instant coffee used — commercial brands vary widely in caffeine content per serving.
It’s named for its resemblance to dalgona, a Korean honeycomb candy. The drink itself originated at a café in Macau and went viral worldwide in March 2020 after a video of actor Jung Il Woo trying it spread on social media.
It exploded on TikTok and YouTube during COVID-19 lockdowns in 2020, when people were stuck at home looking for kitchen projects — its dramatic foam and simple three-ingredient recipe made it especially shareable.
Only a powerful one. Weaker handheld frothers struggle to build the stiff peaks dalgona coffee needs and can take far longer than a mixer, which is the more consistently reliable tool.
The most common causes are using ground coffee instead of instant, not whipping long enough, or using the wrong tool — a blender or immersion blender doesn’t build the right structure. Sugar also isn’t optional; it helps stabilize the foam.
