What You’ll Need
The Matcha Base
Culinary-grade matcha powder is the star here, and quality really matters. Don’t use ceremonial grade (that’s for traditional tea), but don’t go with the cheapest stuff either or it’ll taste bitter and dull. I use this brand from Amazon — it makes a huge difference.
Hot water helps dissolve the matcha powder smoothly before you add the cold ingredients. Just a splash is all you need—about 2 tablespoons of very hot (not boiling) water works perfectly.
The Milk
Whole milk gives you that rich, creamy texture that makes this taste like the real deal. You can absolutely use oat milk or almond milk if you prefer, but whole milk is what gets you closest to the Dunkin’ drinks menu version.
The Sweetener
Liquid cane sugar or simple syrup is key to nailing that Dunkin’ sweetness. Granulated sugar won’t dissolve properly in cold drinks, so you need liquid sweetener. I use this brand from Amazon — it makes a huge difference in getting that smooth, evenly sweet taste.
The Ice
Regular ice cubes are all you need, but I like to use larger cubes so they melt slower and don’t water down the drink too quickly.
🛒 Shopping Tip: If you can’t find liquid cane sugar, you can make simple syrup at home by dissolving equal parts sugar and hot water, then letting it cool. Store it in the fridge for up to a month.
Pro Tips Before You Start
These tips will take your dunkin matcha latte recipe from good to absolutely perfect:
- Sift your matcha powder first — this breaks up any clumps and makes it way easier to dissolve smoothly. I just use a small fine-mesh strainer.
- Use a mini whisk or milk frother to mix the matcha with hot water until it’s completely smooth with no lumps. A spoon works, but a whisk is so much better.
- Let the matcha mixture cool for 30 seconds before adding it to your iced drink, or it’ll melt all your ice immediately and you’ll end up with a watery mess.
- Fill your glass with ice first, then add the milk, then drizzle the matcha mixture on top. This creates that gorgeous layered look before you stir.
- Start with less sweetener than you think you need — you can always add more, but you can’t take it out. I recommend starting with half the amount and adjusting to taste.
- Use cold milk straight from the fridge for the best texture and temperature. Room temperature milk just doesn’t hit the same.
- Stir vigorously before drinking to make sure the matcha is evenly distributed. That first sip should have the perfect balance of matcha and sweetness.
- Make a double batch of the matcha-water mixture and store the extra in the fridge for up to 3 days so you can make these drinks even faster next time.
💡 Pro Tip: The single most important trick? Whisk your matcha with hot water FIRST before adding anything cold. This is the secret to getting that smooth, lump-free consistency that makes this taste professional instead of gritty.

Ingredients
Equipment
Method
-
Add the matcha powder to a small bowl or cup. Pour the hot water over the matcha powder and whisk vigorously with a small whisk or fork for about 30 seconds until the powder is completely dissolved and no clumps remain. The mixture should be smooth and vibrant green with a slight foam on top.
-
Add the liquid cane sugar or simple syrup to the matcha mixture and stir well to combine. The sweetener should blend seamlessly into the matcha, creating a uniform sweet and earthy base. Let this mixture cool for about 1 minute if it’s still very warm.
-
Fill a tall glass with ice cubes, filling it about three-quarters full. The ice should reach near the top of the glass to ensure your drink stays cold and refreshing throughout.
-
Pour the cold milk over the ice in the glass. The milk should fill the glass leaving about an inch of space at the top for the matcha mixture.
-
Pour the sweetened matcha mixture over the milk and ice. You’ll see beautiful green swirls as the matcha cascades through the white milk, creating an Instagram-worthy layered effect.
-
Insert a straw and stir the drink thoroughly from bottom to top for about 10 seconds. The green matcha should blend completely with the milk, creating a uniform pale green color throughout the drink.
-
Taste your matcha latte and adjust sweetness if needed by adding more liquid sugar, stirring well after each addition. The flavor should be creamy, slightly sweet, with the distinctive earthy and grassy notes of matcha coming through.
-
Serve immediately while cold and enjoy your homemade Dunkin’ style matcha iced latte. The drink is best consumed within 10 minutes before the ice dilutes the flavor too much.

Customizations & Variations
One of the best things about making your own dunkin matcha drink dupe is that you can customize it exactly how you like it.
Dairy-Free Version
Swap the whole milk for oat milk or almond milk for a completely dairy-free option. Oat milk is my favorite because it’s naturally creamy and sweet, so you might even need less sweetener. Coconut milk works too, but it adds a distinct coconut flavor that not everyone loves with matcha.
Sugar-Free Option
Use a sugar-free simple syrup or liquid stevia instead of regular sweetener. Start with less than you think you need because sugar-free sweeteners can be much sweeter than regular sugar. You can also try monk fruit sweetener for a natural zero-calorie option.
Hot Matcha Latte
Skip the ice and use hot steamed milk instead for a cozy version. Whisk your matcha with hot water as usual, then add hot (not boiling) milk and your sweetener. If you have a milk frother, foam the milk first for that coffee shop experience at home.
Large Size (Venti/Extra Large)
Simply double all the ingredients and use a larger glass. I like to use a 20-24 oz tumbler for this size. It’s perfect for those days when one regular-sized drink just won’t cut it.
Extra Creamy Version
Add a splash of heavy cream or half-and-half on top of your regular milk for an ultra-rich, indulgent treat. You can also use a flavored creamer like vanilla or sweet cream to add another layer of flavor.
Vanilla Matcha Latte
Add a splash of vanilla extract or vanilla syrup along with your regular sweetener. This tastes amazing and is actually a popular modification that some Dunkin’ locations offer. Start with just 1/4 teaspoon of extract or a pump of syrup.
Seasonal Fall Version
Add a tiny pinch of cinnamon and nutmeg to your matcha mixture for a fall-spiced version. You can also swap some of the regular sweetener for maple syrup for a cozy autumn vibe. Don’t overdo the spices—just a tiny pinch is enough.
Protein-Packed Version
Blend in a scoop of vanilla protein powder with your milk before assembling the drink. This turns your matcha latte into a filling breakfast or post-workout drink. Use an unflavored or vanilla protein powder so it doesn’t clash with the matcha.
Boozy Adult Version
Add a shot of Irish cream liqueur or vanilla vodka for a fun cocktail version. This is perfect for brunch or as a dessert drink. The sweetness of the liqueur means you can cut back on the simple syrup a bit.
Coconut Matcha Latte
Use coconut milk and add a splash of coconut cream on top for a tropical twist. You can also add a tiny drop of coconut extract if you really want to amp up that coconut flavor. This pairs surprisingly well with the earthy matcha taste.
Decaf/Caffeine-Free Option
While traditional matcha does contain caffeine, you can make a decaf version using a matcha-flavored herbal tea blend or look for decaffeinated matcha powder (though it’s harder to find). The flavor won’t be exactly the same, but it’s a good option if you’re sensitive to caffeine.
Storing & Make-Ahead Tips
This matcha green tea latte is best enjoyed fresh, but there are definitely ways to prep ahead and save time on busy mornings.
Make-Ahead Matcha Concentrate
- Mix matcha powder with hot water in a larger batch (4-5 servings worth) and store in an airtight container in the fridge
- Keeps for up to 3 days in the refrigerator—just give it a quick shake before using
- This cuts your prep time down to 30 seconds when you want a drink—just pour over ice and milk
Storing Prepared Drinks
- Fridge storage: up to 24 hours in a sealed container, but the ice will melt and dilute it
- Better option: store the matcha mixture and milk separately and combine fresh with ice when ready to drink
- Give it a good shake or stir before drinking if it’s been sitting, as the matcha can settle
Freezer Tips
- Freeze leftover matcha mixture in ice cube trays for up to 2 months—these matcha ice cubes won’t water down your drink as they melt
- Don’t freeze the complete drink with milk, as dairy doesn’t freeze well and will separate
- Pop 2-3 matcha ice cubes into milk with regular ice for a quick drink
Batch Prep for the Week
- Pre-measure matcha powder into small containers or zip-top bags for grab-and-go convenience
- Make a large batch of simple syrup once a week and keep it in a squeeze bottle in the fridge
- Keep all ingredients in one spot in your fridge so you can make this in under 2 minutes
✅ Note: Matcha powder itself should be stored in an airtight container in a cool, dark place (or even the fridge) to keep it fresh. It can lose its vibrant color and flavor if exposed to air and light for too long.
Frequently Asked Questions
How many calories are in this copycat dunkin matcha latte?
Using whole milk and regular simple syrup, this homemade version has approximately 150-200 calories depending on how much sweetener you use. The Dunkin’ version is similar at around 250 calories for a medium. You can easily cut calories by using almond milk (30-50 calories per cup) and a sugar-free sweetener.
Can I use regular green tea instead of matcha powder?
No, regular green tea won’t give you the same result. Matcha is a specially ground powder that dissolves into the drink and creates that thick, creamy texture. Regular green tea is steeped and strained, so you’d end up with just green-tinted milk. The flavor is also completely different—matcha has that distinctive earthy, slightly sweet taste that regular green tea doesn’t have.
How long does this matcha recipe at home stay fresh?
The prepared drink is best consumed immediately or within 24 hours if stored in the fridge. However, the matcha-water concentrate keeps for 3 days refrigerated, and the dry matcha powder stays fresh for several months when stored properly in an airtight container away from light and heat.
Can I make this the night before for the morning?
You can prep the matcha concentrate the night before and store it separately from the milk. In the morning, just pour it over fresh ice and cold milk for the best texture and taste. I don’t recommend making the complete drink with ice the night before because the ice will melt and water everything down.
Is this healthier than the Dunkin’ version?
Yes, it can be much healthier because you control exactly what goes in it. You can use less sugar, choose higher-quality matcha with more antioxidants, and pick your preferred type of milk. The Dunkin’ version uses a pre-mixed matcha blend that contains sugar and other additives, while this uses pure matcha powder.
Why does my homemade version taste different from Dunkin’s?
Dunkin’ uses a sweetened matcha blend rather than pure matcha powder, which is why theirs is sweeter and has a slightly different flavor profile. If you want it to taste more like theirs, add a bit more sweetener and make sure you’re using culinary-grade (not ceremonial-grade) matcha. Some people also find that adding a tiny pinch of salt helps round out the flavors and makes it taste more like the commercial version.
Can I freeze this drink for later?
I don’t recommend freezing the complete drink because the milk will separate and get grainy when thawed. However, you can freeze the matcha-water mixture in ice cube trays and use those matcha cubes in fresh milk for a quick drink. This actually works really well and prevents dilution as the ice melts!
