Crackly top chewy treat

Featured in: Indulge in Heavenly Sweet Treats

With their sugary, crinkled exterior and a soft, stretchy mochi core, these one-of-a-kind Thai Tea Mochi Cookies offer a perfect balance of textures and flavors. The process involves crafting a mochi filling, wrapping it in aromatic Thai tea-infused cookie dough, and coating it in layers of sugar to get the signature crinkle effect during baking. Though these cookies take a little time, they’re a showstopping mix of warm tea spices and soft chewy textures you’ll love to share.

When you take that first bite of a ThaiTea Mochi Crinkle Cookie, you'll feel like you've stepped into a magical place where flavors from different worlds come together beautifully. The wonderful Thai tea taste in the soft cookie exterior gives way to that chewy mochi middle, making for a treat that you just can't stop eating.

I took these to a block party last week, and I couldn't believe how fast they went. Within minutes, neighbors were crowding around me wanting to know how to make them. My buddy's little girl, who usually won't touch anything 'weird,' gobbled up three straight away and said they were her absolute favorite now. People seem to love how these look familiar but taste so different than what they expect.

Key Ingredients and Smart Shopping Advice

  • Thai Tea Mix: Go for real Thai tea mix with bright orange-red leaves. Try to find Pantai or Number One brands for the truest taste.
  • Glutinous Rice Flour (Mochiko): This is a must-have and you can't swap it out for normal rice flour. It's what gives you that stretchy, chewy texture we want.
  • Fresh Milk: Grab whole milk to get the most flavor when you mix in the Thai tea. The fat helps pull out all those good flavors.
  • Quality Butter: Treat yourself to good unsalted butter for the cookie part. The fancy European stuff with extra fat makes for super tender cookies.
  • Powdered Sugar: This creates that pretty crackled coating and adds sweetness without any gritty feeling. Make sure yours is fresh with no lumps.

I've learned that using top-notch Thai tea mix really changes how these cookies turn out, both in color and taste. That lovely orange shade and unique spiced flavor comes from real Thai tea, not regular black tea with color added, which some folks suggest you can use instead.

Step-By-Step Baking Guide

Step 1: Get Your Mochi Center Ready
Mix 1 cup glutinous rice flour, 2 tablespoons cornstarch, 1/4 cup sugar, 1 tablespoon coconut oil, and 3/4 cup milk in a bowl safe for microwaving. Heat it in 30-second bursts, giving it a stir each time, until it turns see-through and gooey. Sprinkle cornstarch on your counter, dump out the mochi, and shape it into 12 little balls.
Step 2: Make Your Tea Mixture
Take 3 tablespoons of loose Thai tea and grind it up fine in a spice grinder, then sift out any big pieces. Warm up 1/3 cup milk until it's just hot, add 2 tablespoons of your ground tea, and let it sit for 10 minutes. Strain it through a fine strainer, pushing down to get all the flavor out.
Step 3: Put Together Your Cookie Mix
In a medium bowl, stir together 1¾ cups all-purpose flour, 1½ teaspoons baking powder, and ½ teaspoon salt. In another bigger bowl, mix ½ cup melted butter, 1 cup granulated sugar, 1 egg, 1 teaspoon vanilla extract, and your Thai tea milk. Slowly add the dry stuff to the wet stuff just until they're combined. Let the dough cool in the fridge for at least 2 hours.
Step 4: Put The Cookies Together
Scoop tablespoon-sized chunks of cold dough. Flatten each piece, stick a mochi ball in the middle, and carefully wrap the dough all around it, making sure to seal it up good. Roll each ball first in regular sugar, then coat it really well in powdered sugar. You need both layers to get that cool crackly look.
Step 5: Bake Them Up
Put your cookies on a baking sheet lined with parchment paper, keeping them at least 2 inches apart. Bake them in a 350°F oven for 11-13 minutes until the edges feel set but the middle is still soft. Let them sit on the pan for 5 minutes before moving them to a cooling rack. The cracks will show up as they bake and cool down.

When I first tried making these, I got so worked up about getting the wrapping just right. After a few wonky attempts, I realized that simple folds work fine too - they taste just as amazing either way. These days my kids jump in to help with the folding, each coming up with their own special way that's now part of how we make these together.

Achieving That Wonderful Texture Combo

What makes these cookies so special is how they feel when you bite them - crispy bottoms with soft, flavorful insides. I've found that managing moisture is super important here. First, you need to really squeeze out that salted cabbage so it doesn't make everything soggy. Then, the cornstarch doesn't just hold stuff together - it soaks up extra water too. And finally, that cooking method - frying, then steaming, then frying again - gives you that awesome crispy bottom while making sure the filling cooks all the way through.

Planning Ahead For Parties

The best thing about this recipe is how you can break it up into steps when you're having people over. I often do it in parts: shape and freeze the balls up to a month ahead, bread them the day before and keep them covered in the fridge, then just bake them right before guests show up. The smell of them baking fills your home with an amazing scent that gets everyone excited to eat. For bigger gatherings, I make two batches, keeping the second one warm in a low oven until we need them.

New Ways To Use Any Extras

If you happen to have leftover cookies (which hardly ever happens at my place!), you can turn them into completely different dishes. Break them up and mix them into scrambled eggs for a French-style breakfast, or cut them up and toss them into a simple green salad with a spicy dressing for lunch. My favorite trick is to put cookie halves on top of a bowl of creamy grits, which makes for a tasty breakfast that carries the flavors into the next day.

Smart Cooking Tricks

  • Let the balls cool for 5 minutes after they come out of the oven – this helps the inside set up for the perfect bite
  • Try adding a teaspoon of smoked paprika to your panko mix for extra flavor
  • If you can't find cookies in stores near you, try ordering online from places like Bourgeois Meat Market or The Best Stop
  • Put out several dipping options – spicy remoulade and cool ranch along with the Louisiana sauce
  • For a fancy presentation, set the balls on a platter with bits of chopped parsley, purple cabbage, and yellow bell pepper scattered around to show the traditional green, purple, and gold colors

Frequently Asked Questions

→ What’s Thai tea and where can I get it?
Thai tea is a spiced black tea blend, often flavored with tamarind, cardamom, and star anise. You can snag it at Asian grocery stores, tea specialty shops, or even online. If needed, strong black tea with a pinch of ground star anise can work, but it won’t taste quite the same.
→ Can I prep the mochi beforehand?
Absolutely, you can prepare the mochi up to a day early. Wrap it tightly in plastic to avoid drying, and leave it at room temperature. If it's too sticky later, dust with a little cornstarch to make it easier to handle.
→ Why use granulated sugar under the powdered coating?
The first sugar layer protects the powdered sugar from disappearing into the dough when baking. That’s how you get those bright white cracks on top. Skipping this step may cause the sugar topping to fade.
→ Can I swap glutinous rice flour with regular flour?
Sorry, it won’t work. Glutinous rice flour is what gives mochi its stretchy, chewy texture. Despite the name, it’s gluten-free—‘glutinous’ refers to its stickiness when cooked.
→ Why didn’t my cookies crinkle enough?
Crackles form when the surface bakes faster than the inside. Make sure your dough is chilled, use plenty of powdered sugar, and don’t press the dough balls too flat. Preheating the oven is important too!
→ What’s the best way to store them?
Keep them in a container with a tight lid at room temperature for 2-3 days. The chewy filling softens over time, so they’re at their best on bake day. Need to keep them longer? Freeze for up to a month and defrost at room temp to serve.

Ingredients

→ Mochi Base

01 250g of milk
02 120g glutinous rice flour
03 35g white sugar
04 Cornstarch for dusting
05 15g coconut oil

→ Dough for Thai Tea Cookies

06 1½ tsp of baking powder
07 2 eggs
08 90g melted unsalted butter
09 160g sugar
10 240g plain flour
11 35g milk
12 2½ tbsp finely ground Thai tea leaves
13 1 tsp table salt
14 1 tsp vanilla essence

→ Sugar Coating

15 Icing sugar
16 Granulated sugar

Instructions

Step 01

In a microwaveable mixing bowl, stir together the rice flour, sugar, and milk. Use plastic wrap to cover before heating for 60 seconds.

Step 02

Take the bowl out and stir the contents briskly to mix any remaining liquid. Cover again and heat once more for 1 minute.

Step 03

Mix in the coconut oil while the mochi is warm until smooth. Cover up and put aside to let it rest for at least 10 minutes.

Step 04

Sprinkle your work area lightly with cornstarch. Once cool, turn the mochi out, knead it quickly, and divide it into 12 equal parts. Coat each part with cornstarch and save them for later.

Step 05

Use a mortar and pestle, spice grinder, or food processor to crush the tea into a finely powdered texture. Pass it through a sieve to remove bigger bits. You’ll need about 2½ tbsp of the fine powder.

Step 06

Add the crushed tea to 35g of milk in a bowl. Mix well and let it soak for a minimum of 5 minutes.

Step 07

Mix up the flour, salt, and baking powder in a medium-sized bowl. Set it aside for later.

Step 08

In a large bowl, beat together the melted butter and sugar. Add the eggs, vanilla, and the milk-tea mixture. Stir until smooth.

Step 09

Fold the dry mix into the wet one until just incorporated—no need to overdo it. Cover and chill the dough in the fridge for 2 hours, or overnight if you’ve got more time.

Step 10

Preheat your oven to 350°F (180°C). Lay some parchment paper on a baking tray, and set up two small bowls: one with granulated sugar, one with icing sugar.

Step 11

Take the cookie dough and divide it into 12 equal-sized lumps (about 45-50g per piece). Flatten each one slightly, pop a mochi piece in the middle, and fold the dough up to fully cover it. Roll to smooth out.

Step 12

Coat each dough ball first in granulated sugar, then give it another coating with a layer of powdered sugar. Put them on the lined tray, leaving about 1-1.5 inches of space between.

Step 13

Bake for 12-15 minutes, until the tops crack and the edges look golden. Leave them on the hot tray for 2 minutes, then transfer to a cooling rack.

Notes

  1. These treats pair the crisp and flaky texture of cookies with a soft, chewy mochi middle. The Thai tea gives them a bold, aromatic flavor inspired by a mix of two cuisines.
  2. If shaping the cookies takes time and the dough gets too soft, pop it back into the fridge for 15-30 minutes before adding the sugar coatings.
