Homemade Thai Iced Tea Recipe: Creamy Spiced Cha Yen

 

Thai iced tea — cha yen — is impossible to forget once you've had the real thing: bold, spiced black tea poured over ice, then swirled with condensed and evaporated milk until it marbles into that famous creamy orange sunset. This homemade version nails the coffee-shop look and taste with pantry spices and about 20 minutes.

The key is brewing the tea strong. Thai tea is meant to be intense — it gets diluted by melting ice and sweetened by rich milk, so what tastes "too strong" in the pot lands perfectly in the glass. Don't rush the steep, and always pour the milk over the ice so it swirls instead of mixing.

That creamy swirl is the signature cha yen moment.

Recipe Info

• Prep time: 5 minutes
• Cook time: 10 minutes
• Total time: 20 minutes, plus cooling
• Servings: 4 glasses (about 350 ml each)
• Calories: approx. 210 kcal per glass

Bold tea, warm spices, and two kinds of milk.

Ingredients

• For the spiced tea:
• 1 L (4¼ cups) water
• 6 tbsp (about 30 g) loose black tea (or 6 black tea bags)
• 2 whole star anise
• 1 cinnamon stick
• 3 green cardamom pods, lightly crushed
• 3 whole cloves
• 80 g (⅓ cup + 1 tbsp) sugar
• For serving:
• 120 ml (½ cup) sweetened condensed milk
• 180 ml (¾ cup) evaporated milk
• Plenty of ice cubes
• Fresh mint sprigs (optional)

Watch the milk marble through the tea — pour it tableside.

Instructions

1. Toast the spices. In a dry saucepan over medium heat, toast the star anise, cinnamon, cardamom, and cloves for 1–2 minutes until fragrant. This wakes up their flavor before the water goes in.
2. Brew the tea. Add the water and bring to a rolling boil. Turn off the heat, add the tea leaves and sugar, and steep for 5–7 minutes, stirring once. It should look dark and smell intensely spiced.
3. Strain and cool. Strain through a fine-mesh sieve (or a coffee filter for a clearer tea) into a pitcher. Let cool to room temperature, then refrigerate at least 1 hour — hot tea poured over ice just makes a watery drink.
4. Fill the glasses. Fill 4 tall glasses to the top with ice. Pour the chilled tea over, leaving about 5 cm (2 in) of space at the top of each glass.
5. Mix the milks. In a small jug, stir together the condensed milk and evaporated milk until smooth and uniform.
6. Pour the swirl. Slowly pour about 75 ml (5 tbsp) of the milk mixture over the back of a spoon into each glass. Watch it ribbon and marble through the tea — that's the cha yen signature.
7. Serve. Garnish with a mint sprig if you like, hand everyone a long spoon or straw, and serve immediately before the ice melts.

Tips & Variations

• Chill everything: Cold tea plus cold glasses equals slow-melting ice and a drink that stays bold to the last sip. Room-temperature tea is the number-one cause of weak Thai iced tea.
• Don't over-steep: Past 8 minutes the tea turns bitter and tannic. Strong is good; bitter is not — set a timer.
• Thai tea mix shortcut: If you find Thai tea mix (the pre-spiced orange powder), use 6 tbsp and skip the separate spices and sugar adjustment — sweeten to taste.
• Adjust the sweetness: Start with the listed sugar and taste after chilling. Traditional cha yen is very sweet; reduce sugar by a third for a more modern, tea-forward glass.
• Dairy-free version: Swap the condensed milk for sweetened condensed coconut milk and the evaporated milk for coconut milk or oat milk. Still creamy, still swirly.
• Make it a float: A scoop of vanilla or coconut ice cream on top turns cha yen into a Thai iced tea float — dangerous and delicious.
• Batch for a party: Double the tea base and keep it in the fridge up to 3 days. Assemble per glass so everyone gets the fresh swirl.

Nutrition Note

At about 210 kcal per glass, Thai iced tea is a treat, not an everyday drink — most of the calories come from the condensed milk and sugar, and the caffeine sits roughly between a cup of coffee and a strong black tea. For a lighter glass, cut the condensed milk in half, use low-fat evaporated milk, and let the bold tea do more of the talking.

FAQ

What is cha yen?
Cha yen is Thailand's iconic iced tea: strongly brewed spiced black tea sweetened with condensed milk and evaporated milk, poured over ice so the milk swirls through it.

Why is Thai iced tea orange?
The vivid color comes from the tea itself — Thai tea blends include food coloring (usually yellow/orange) along with spices. Homemade versions with plain black tea are a deeper amber but taste just as good.

Can I use tea bags instead of loose tea?
Yes — 6 strong black tea bags (like Assam or Ceylon) work fine. Squeeze the bags gently when removing them to get the full strength.

How long does the tea base keep?
The strained, unsweetened tea base keeps 3 days refrigerated in a sealed pitcher. Sweetened with milk, serve within a few hours.

Is Thai iced tea very caffeinated?
Each glass has roughly the caffeine of a strong cup of black tea — noticeable, but less than coffee. Avoid it late in the evening if you're caffeine-sensitive.
