Dalgona Coffee — THE Original TikTok Food Trend (1.8 Billion Views)

Before baked feta pasta, before birria tacos, before butter boards — there was Dalgona coffee. It was March 2020. The world had just gone into lockdown. Everyone was stuck at home, bored, anxious, and scrolling TikTok. And then someone posted a video of whipping instant coffee into a cloud.

1.8 billion views. That’s not a typo. Billion with a B.

The trend started in South Korea (the name comes from dalgona, a Korean sugar candy with a similar color and texture). Actor Jung Il-woo tried it on a Korean TV show, it jumped to TikTok, and within two weeks every person on earth was whipping instant coffee in their kitchen. It was the first truly global TikTok food trend, and it happened because the entire planet was at home with nothing to do and three ingredients in their pantry.

Why It Went Viral

Perfect timing. March 2020. Lockdown. Everyone’s home. Cafes are closed. People missed their morning coffee ritual. Dalgona gave them something to make that felt special — a little moment of joy when everything was falling apart. It was comfort content at exactly the right time.

Three ingredients. Instant coffee. Sugar. Hot water. That’s it. No special equipment needed (though a hand mixer helps). No obscure ingredients. You could make this at midnight with what was already in your kitchen. The accessibility is what made it truly universal — people in Tokyo, Lagos, Buenos Aires, and Tulsa were all making the exact same recipe.

The visual transformation. Dark brown liquid turning into fluffy, caramel-colored foam — it’s mesmerizing. Then spooning that cloud on top of white milk — the two-tone contrast is gorgeous. It’s engineered for photos and video. Every single person who made it posted it.

The sound. The whipping noise, the satisfying plop of foam onto milk, the clink of the spoon on the glass. Food ASMR before food ASMR was a genre.

The Science Behind the Foam

Instant coffee is the key and there’s no substitute. Regular brewed coffee or fresh grounds won’t work. Here’s why: instant coffee contains compounds called melanoidins (created during the spray-drying manufacturing process) that act as natural surfactants. These molecules trap air during whipping, creating a stable foam — similar to how proteins in egg whites create meringue.

The sugar isn’t just for sweetness — it increases the viscosity of the liquid, helping the foam hold its structure. The hot water dissolves the coffee and sugar quickly and completely, giving you a smooth base to whip.

The 1:1:1 ratio is non-negotiable. More water and it won’t foam. More coffee and it’s too bitter. More sugar and it collapses under its own weight.

The Mistakes Everyone Makes

Using brewed coffee or ground coffee. Won’t work. The science literally requires instant coffee powder. Regular coffee doesn’t have the melanoidins needed for foam structure. This is the number one comment on every dalgona video: “why isn’t mine foaming?” Because you used regular coffee.

Not whipping long enough. It takes 3-5 minutes with an electric mixer, or 10-15 minutes by hand. Most people give up too early. If it’s still liquid-y, keep going. It WILL get there.

Using cold water. The coffee and sugar need to dissolve completely before you start whipping. Cold water leaves granules that prevent proper foam formation.

Making it too sweet. The 1:1 coffee-to-sugar ratio makes a pretty sweet drink. If you want less sweet, reduce the sugar slightly BUT add a pinch of xanthan gum or cream of tartar to help stabilize the foam — it won’t hold as long without the sugar.

Tips

• Hand whisk workout: If you don’t have an electric mixer, use a regular whisk. It takes about 400-500 strokes and 12-15 minutes. People called it the “quarantine arm workout.” It genuinely builds muscle.
• Make it hot: Skip the ice, heat the milk, and spoon the foam on warm milk for a cozy version.
• Batch prep: Make extra foam and store it in the fridge. It holds for up to 24 hours. Spoon onto fresh milk whenever you want.
• Matcha version: Replace instant coffee with 2 tablespoons matcha powder. Add 2 tablespoons sugar and 2 tablespoons hot water. The whipping takes longer but you get a green tea version.
• Flavor it: Add a drop of vanilla extract or a pinch of cinnamon to the foam before whipping.

The Michelin Twist

Use brown sugar instead of white for a deeper, more caramel-like flavor in the foam. Add a shot of espresso to the milk underneath for a double-coffee hit with more complexity. Shave dark chocolate over the foam with a microplane instead of dusting cocoa. For the glass, rim it with a mix of espresso powder and raw sugar — like a coffee margarita. Serve with a thin biscotti on the side. It goes from “pandemic kitchen project” to “coffee bar at a boutique hotel.”

The Cultural Moment

Dalgona coffee wasn’t just a recipe. It was a collective experience. During the loneliest stretch many of us had ever lived through, millions of strangers made the same drink at the same time and shared it with each other. The #dalgonacoffee hashtag became a global community. People posted their attempts, their failures, their arm cramps from hand-whisking. It was silly, it was sweet, and it made a terrible time slightly less terrible.

That’s why it hit 1.8 billion views. Not because it’s the best coffee you’ll ever have. But because it was the right thing at the right time.

Cost Breakdown

A jar of instant coffee ($5) makes about 30 servings of dalgona foam. Sugar and hot water are basically free. Milk costs what milk costs. You’re looking at roughly $0.30 per drink vs $5-7 for a fancy coffee at a cafe. During lockdown, when everyone was watching their spending, that math hit different.

The Bottom Line

Dalgona coffee is patient zero for TikTok food trends. It proved that simple recipes with visual payoff could reach billions of people overnight. It launched a thousand imitators and established the formula that every viral food trend since has followed: few ingredients, satisfying process, beautiful result. If TikTok food had a Mount Rushmore, dalgona coffee would be face number one.
