How to Make Thai Iced Coffee with Cardamom and Cream

You’re sweating through a summer afternoon and craving something cool—but not just any iced coffee. You want that sweet, creamy, spiced drink that tastes like a beachside escape. The kind that hits you with cardamom, then fades into whipped cream and sugar, with a deep coffee kick underneath. That’s Thai iced coffee. But how do you actually make it?

To make a classic Thai iced coffee, use a very strong brewed coffee—about 1.5 to 2 times stronger than your usual brew. Extract it with green cardamom, cool it, then pour it over ice with sugar dissolved in a bit of the coffee. Top with whipped cream and serve with a straw. A condensed milk variation is also common.

What Is Thai Iced Coffee?

Thai iced coffee (or โอเลี้ยง / oleang) is a sweet, creamy, spiced cold coffee drink that originates from Thailand. It combines a highly concentrated coffee brew with crushed ice, sweetened condensed milk or sugar, and often green cardamom. The result is a chilled drink with a bold coffee flavor, creamy texture, and a hint of exotic spice—often finished with a dollop of whipped cream and colorful paper umbrellas for that classic Thai café vibe.

Why It Tastes So Unique

The unique flavor of Thai iced coffee comes from several factors: the use of strong, dark-roasted coffee brewed extra concentrated; the addition of green cardamom, a warm, aromatic spice from the Indian subcontinent; and the contrast of cold ice, creamy milk or cream, and sweetener. The combination delivers a layered taste experience: initial sweetness and creaminess, followed by spicy cardamom notes, and a deep, bold coffee finish. It’s designed to be refreshing yet indulgent.

How to Make Traditional Thai Iced Coffee Step by Step

Making Thai iced coffee involves brewing an extra-strong coffee, cooling it, mixing it with sugar and ice, and topping it with whipped cream. Here’s the exact method:

• Coffee Brew: Use a dark roast coffee bean. Grind it appropriately for filter brewing (not espresso). Use 1.5 to 2 times the amount of coffee you’d normally use for a regular brew. For example, if you typically use 20g, use 30–40g.
• Spice Addition: Add 2–3 fresh green cardamom pods (crushed or whole) to the coffee grounds or place them on the filter with the coffee during brewing. Brew as normal.
• Cooling: Allow the brewed coffee to cool at room temperature or refrigerate briefly before using.
• Sugar Syrup (Optional): In a tall glass, dissolve 1–2 teaspoons of granulated sugar in a small amount of the hot or warm coffee (about 20–30ml).
• Assembling the Drink: Fill the glass with 5–6 ice cubes. Pour the cooled coffee into the glass, leaving about 2cm of space from the top.
• Whipped Cream: Insert a spoon into the glass, and slowly drizzle 1–2 tablespoons of freshly whipped cream over the back of the spoon so it floats on top of the coffee. Gently remove the spoon.
• Serve: Insert a straw and optionally top with a colorful paper umbrella. Serve immediately.

The Condensed Milk Variation

If you prefer a simpler or more traditional Thai street-style version, you can skip the whipped cream and sugar syrup. Instead:

• Add 1–2 tablespoons of sweetened condensed milk to the bottom of the glass.
• Pour the strong brewed coffee over the condensed milk.
• Add ice cubes (preferably after pouring the coffee to avoid dilution).
• Optionally, top with a small amount of whipped cream as well—this is commonly seen in Thailand even when condensed milk is used.

Making Strong Coffee for Thai Iced Coffee

Thai iced coffee relies on a very concentrated brew to hold up against the ice and cream. Some brewers use a stovetop Moka pot or even prepare espresso-like coffee using a device similar to an espresso maker. One alternative method mentioned is combining finely ground dark roast coffee with cardamom, then brewing it in an espresso-style device to produce a very strong shot of coffee. Alternatively, you can use a French press, pour-over, or drip machine with a higher coffee-to-water ratio:

• Brew ratio: Around 1:8 to 1:10 (coffee to water), or even stronger.
• Grind size: Medium-fine to fine, depending on your brew method.
• Brew time: Adjust to ensure a bold extraction without over-extraction bitterness.

FAQ

Do I have to use cardamom in Thai iced coffee?

No, cardamom is traditional but optional. The drink is still considered Thai iced coffee without it, though the green cardamom is a key part of the classic flavor profile that gives it an aromatic, slightly spicy edge. Omitting it will result in a simpler sweet coffee with cream.

Can I use any coffee bean for Thai iced coffee?

It’s best to use a dark roasted coffee bean for a bold, rich flavor that stands up to the milk, sugar, and ice. FrontStreet Coffee’s Classic Blend is a suitable choice for a rich, full-bodied brew. Lighter roasts may lack the body needed for this style of drink.

What’s the best way to cool the coffee?

Allow the brewed coffee to cool to room temperature naturally, or refrigerate it briefly if you’re in a hurry. Avoid adding ice directly during the brew, as it will water down the strength.

Is whipped cream necessary?

No, whipped cream is optional. The traditional version often uses just condensed milk and sugar, with whipped cream added for a more indulgent café-style presentation. You can skip it or substitute it based on preference.

Can I make Thai iced coffee ahead of time?

You can brew the concentrated coffee ahead and refrigerate it, but assemble the drink (with ice, cream, and toppings) just before serving to maintain texture and prevent excessive dilution or melting.
