What Is Dalgona Coffee?

Dalgona coffee is a whipped coffee drink made by beating instant coffee, sugar, and hot water into a thick, creamy foam, then spooning it over cold (or hot) milk. The name comes from a Korean sugar candy with a similar colour and sweetness. It became a global sensation and has since become a staple home coffee recipe that anyone can make — no special equipment needed.

Ingredients (Serves 1–2)

  • 2 tablespoons instant coffee (use a good-quality instant for best results)
  • 2 tablespoons white sugar (granulated works well; try brown sugar for a richer flavour)
  • 2 tablespoons hot water
  • 200–250ml cold milk per serving (dairy or plant-based both work)
  • Ice cubes — for the classic iced version

Equipment

  • A mixing bowl
  • A hand whisk, hand mixer, or electric frother
  • A tall glass
  • A spoon for serving

Step-by-Step Instructions

  1. Combine the three ingredients — Add the instant coffee, sugar, and hot water to your mixing bowl. Make sure they're equal parts by volume.
  2. Whip until thick and fluffy — Using a hand mixer, this takes about 2–3 minutes. With a manual whisk, expect 8–12 minutes of vigorous whisking. You're looking for a light, caramel-coloured foam that holds stiff peaks when you lift the whisk.
  3. Prepare your glass — Fill a tall glass with ice cubes and pour in your cold milk.
  4. Spoon the coffee foam on top — Pile the whipped coffee generously over the milk. It should float and hold its shape.
  5. Stir before drinking — Mix the foam into the milk before each sip, or enjoy the contrast of creamy foam and cold milk separately as you drink.

Tips for Perfect Dalgona Coffee

  • Use equal ratios — The 1:1:1 ratio of coffee, sugar, and water is essential. Changing these proportions affects how well the foam whips and holds.
  • Hot water is key — Cold water won't dissolve the sugar and coffee properly. Use freshly boiled water.
  • Don't underwhip — The foam needs to be stiff enough to hold its shape on top of the milk. Keep going until it looks like whipped cream.
  • Chill your glass — For extra refreshment, pop your glass in the freezer for a few minutes before assembling.
  • Choose your milk wisely — Oat milk adds a natural sweetness, almond milk keeps it lighter, and full-fat dairy gives the richest contrast to the strong coffee foam.

Delicious Variations to Try

Matcha Dalgona

Replace instant coffee with matcha powder. Whip with sugar and warm (not boiling) water. The result is an earthy, slightly sweet green foam over milk — beautiful and delicious.

Mocha Dalgona

Add a teaspoon of cocoa powder to your coffee mixture before whipping. You'll get a richer, chocolatey foam with all the boldness of the original.

Hot Dalgona

Skip the ice and pour warm milk instead of cold. The foam melts gently into the milk for a cosy, creamy coffee drink — like a deconstructed cappuccino.

Brown Sugar Dalgona

Swap white sugar for brown or coconut sugar for a deeper, caramel-like sweetness in the foam.

Storage

The whipped coffee foam can be made ahead and stored in an airtight container in the refrigerator for up to 2 days. Give it a quick stir before using — it may deflate slightly but will still taste great.

Dalgona coffee is one of those rare recipes that looks impressive, tastes genuinely delicious, and requires almost nothing in the way of skill or equipment. It's the perfect place to start if you're building your home coffee recipe repertoire.
