The first time I drank Thai tea, I was sitting on a plastic stool in Bangkok's Chinatown, watching condensed milk swirl like a ribbon through amber liquid. That flavor, sweet and spiced, stayed with me for years, and this cookie is my way of carrying it home.

These Thai Tea Sugar Cookies take that same brewed tea and fold it into a soft, buttery dough. The result is a cookie that tastes like a memory: warm, fragrant, and just sweet enough to make you reach for a second one before the first is finished.
You do not need a plane ticket to make them. A saucepan, a whisk, and a bag of Thai tea mix are all it takes to bring a little of that street-corner warmth into your own kitchen.
Why You'll Love This Recipe
About the Ingredients
2 1/4 cups (280g) all-purpose flour
This is your structure. If you want a slightly nuttier cookie, swap 1/2 cup of it for toasted rice flour, which also keeps the texture tender.
1 teaspoon baking soda
Fresh baking soda matters here; if yours has been open for more than six months, buy a new box or the cookies will spread flat.
1 teaspoon cornstarch
Cornstarch is the quiet hero that makes these cookies chewy instead of cakey. You can substitute an equal amount of tapioca starch if needed.
1/2 teaspoon fine sea salt
Salt balances the sweetness of the tea mix. If you only have kosher salt, use a slightly heaping 1/2 teaspoon.
3/4 cup (170g) unsalted butter, softened
Softened means it holds a fingerprint but is not greasy. Salted butter works too; just reduce the added salt to 1/4 teaspoon.
1 cup (200g) granulated sugar
This goes into the dough for sweetness and into a bowl for rolling. If you want a deeper caramel note, use 3/4 cup white and 1/4 cup light brown sugar.
1 large egg plus 1 large egg yolk, room temperature
The extra yolk adds richness and chew. Let them sit on the counter for 20 minutes; cold eggs can make the butter seize.
2 teaspoons vanilla extract
Use real vanilla, not imitation, because the tea flavor is delicate and deserves a clean backdrop. A vanilla bean paste is a lovely upgrade.
1/3 cup (40g) Thai tea mix, brewed strong and cooled
Look for the orange-labeled Thai tea mix at Asian markets or online. If you cannot find it, use 2 black tea bags plus 1/4 teaspoon ground star anise and 1/8 teaspoon cardamom.
1/4 cup (30g) powdered Thai tea mix, for rolling
This is the dry mix, not brewed, and it gives the cookies their signature color and a faint crunch. If you prefer, roll in plain granulated sugar instead.
1/2 cup (60g) sweetened condensed milk
This is the ingredient that makes the cookie taste like the drink. Coconut condensed milk is a good dairy-free swap.
Tips & Tricks
- Chill the dough for at least 30 minutes before baking so the butter firms up and the cookies do not spread into thin discs.
- Brew the tea double strength and let it cool completely; warm liquid will melt the butter and ruin the dough's texture.
- Scoop the dough with a 2-tablespoon cookie scoop so every cookie bakes at the same rate and looks uniform.
- Do not overbake; pull the cookies when the centers still look slightly underdone, because they set as they cool on the pan.
Pro Tips
Step-by-Step Instructions
1. Brew the tea
Steep 1/3 cup Thai tea mix in 1 cup boiling water for 5 minutes, then strain and cool completely. You need 1/3 cup of the brewed liquid; drink the rest with condensed milk.
2. Whisk dry ingredients
In a medium bowl, whisk together the flour, baking soda, cornstarch, and salt until no streaks remain. Set aside.
3. Cream butter and sugar
Beat the softened butter and 1 cup granulated sugar on medium speed for 2 minutes until pale and fluffy. Scrape down the bowl so nothing hides at the bottom.
4. Add wet ingredients
Beat in the egg, egg yolk, vanilla, cooled tea, and condensed milk one at a time, mixing just until combined. The mixture will look slightly curdled, which is normal.
5. Fold in the flour
Add the dry ingredients in two additions on low speed, mixing until the flour just disappears. Overmixing here makes tough cookies, so stop as soon as it comes together.
6. Chill the dough
Cover the bowl and refrigerate for 30 minutes. This firms the butter and lets the tea flavor bloom into the dough.
7. Heat the oven
Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper. Position racks in the upper and lower thirds of the oven.
8. Scoop and roll
Scoop 2-tablespoon balls of dough, roll each in the powdered Thai tea mix, and place 2 inches apart on the prepared sheets. Flatten each ball slightly with the palm of your hand.
9. Bake the cookies
Bake for 10 to 12 minutes, until the edges are set and the centers look soft and glossy; an instant-read thermometer in the center should read about 175°F (79°C). The tops will crackle as they cool.
10. Cool and serve
Let the cookies rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Serve with a glass of cold Thai tea or strong coffee.
Delicious Variations
Thai Tea White Chocolate Cookies
Fold 3/4 cup white chocolate chips into the dough before chilling for a creamier, dessert-bar feel.
Dairy-Free Thai Tea Cookies
Swap the butter for vegan butter and the condensed milk for coconut condensed milk; the texture stays remarkably close.
Spiced Thai Tea Snickerdoodles
Add 1/2 teaspoon ground cinnamon and 1/4 teaspoon cardamom to the rolling mix for a warmer, chai-like finish.
How to Store Thai Tea Sugar Cookies
Refrigerator
Store baked cookies in an airtight container at room temperature for up to 4 days, or refrigerate for up to 1 week to keep them extra chewy.
Freezer
Freeze baked cookies in a single layer, then transfer to a freezer bag for up to 2 months; freeze raw dough balls the same way and bake from frozen, adding 2 minutes.
Reheating
Warm refrigerated or frozen cookies in a 300°F (150°C) oven for 3 to 4 minutes, or microwave for 10 seconds, to bring back the soft center.
Frequently Asked Questions
Q: Can I use regular black tea instead of Thai tea mix?
Yes, you can substitute 2 black tea bags plus 1/4 teaspoon ground star anise and 1/8 teaspoon cardamom for the Thai tea mix. The flavor will be slightly less sweet and more spiced, so add an extra tablespoon of condensed milk if you want it closer to the original.
Q: Why did my Thai tea cookies spread flat?
Your butter was probably too warm or the dough was not chilled long enough. Chill the dough for a full 30 minutes, and if your kitchen is hot, pop the portioned dough balls in the fridge for 10 minutes before baking.
Q: How do I know when these cookies are done?
Pull them when the edges are set and the centers still look soft and slightly glossy, about 10 to 12 minutes at 350°F (175°C). An instant-read thermometer in the center should read about 175°F (79°C); they firm up as they cool.
Q: Can I make the dough ahead of time?
Yes, the dough keeps in the refrigerator for up to 3 days, tightly covered. Let it sit at room temperature for 15 minutes before scooping so it is soft enough to roll without cracking.
Q: Are Thai tea sugar cookies very sweet?
They are moderately sweet, closer to a snickerdoodle than a frosted cookie. The condensed milk and sugar balance the tea's bitterness, but if you want less sweetness, reduce the granulated sugar to 3/4 cup.
Bake a batch this weekend, pour yourself a glass of cold Thai tea, and let the smell fill your kitchen with a little bit of Bangkok. If you make them, tell me how they turned out, and share them with someone who needs a sweet moment. Go, see, and connect.
