Starbucks Matcha Latte Oat Milk: Why This Drink Became a Favorite
From Texas Kitchens to Starbucks Counters
I still remember the first time I tried a Starbucks Matcha Latte with oat milk. It was a sweltering South Texas morning, and I was standing in line at a busy drive-thru near Austin. I’d usually go for cold brew, but the woman ahead of me ordered this vivid green drink.
The barista handed it to her with a smile and said, “It’s our best non-dairy matcha option.” That stuck with me. I added one to my order—and just like that, I was hooked.
Back home, I started experimenting. Growing up, my mom ran a food truck that made everything from scratch, and I’ve always believed you can make anything better at home.
So I bought matcha, grabbed oat milk, and started whisking. After a few tries, I had it down—a copycat Starbucks Matcha Latte Oat Milk that tasted just as good, without the extra syrup or price tag.
What Makes the Starbucks Matcha Latte Oat Milk So Popular?
The secret is in the simplicity. This drink combines bold matcha green tea powder, creamy oat milk, and a touch of sweetness for a smooth, comforting sip. It works hot or iced, morning or afternoon. And for anyone avoiding dairy or cutting back on sugar, it’s a flexible favorite.
People love this drink not just for its flavor—but because it feels like a healthy indulgence. With oat milk’s natural creaminess and matcha’s earthy flavor and antioxidants, it hits that rare balance of feel-good and taste-great.
That’s why so many are searching for ways to make the Starbucks matcha latte oat milk at home—and why this guide gives you everything you need to do it right.

Calories in a Starbucks Matcha Latte with Oat Milk
If you’re ordering a Starbucks Matcha Latte with oat milk, here’s what you’re sipping nutritionally:

If you’re going iced, you’ll shave off a few calories due to the ice content, while hot versions use more oat milk and run slightly higher in carbs and calories.
Why Oat Milk Makes a Difference
Oat milk plays a big role in the texture and taste of this drink—and in its nutritional profile:
- Offers a naturally sweet, creamy texture that balances matcha’s earthy flavor
- Contains about 120 calories per cup
- Has no cholesterol and less saturated fat than whole milk
- Froths easily, making it ideal for lattes
- Typically fortified with calcium and vitamins
Compared to dairy or almond milk, oat milk adds both richness and fullness to the drink. It’s one reason why the Starbucks matcha latte with oat milk is such a popular go-to for both plant-based and flavor-focused drinkers.

How to Order a Healthier Matcha Latte at Starbucks
Cut the Sugar Without Losing the Flavor
If you’re watching calories or cutting sugar, the default Starbucks Matcha Latte oat milk might not be your best bet—at least not without a few adjustments. Starbucks’ matcha powder comes pre-sweetened, so every scoop adds both flavor and sugar. But there are ways to clean it up without compromising taste.
Here’s how to order smarter:
- Ask for fewer scoops of matcha—try 2 instead of 3 for a grande
- Go light on oat milk or ask for half oat milk, half water
- Skip the classic syrup—it’s often added by default when you customize
- Add cinnamon or a dash of vanilla powder instead of flavored syrups
- Choose the tall size if you want the flavor with fewer carbs
Even with oat milk, a grande can pack 28g of sugar. Cutting just one scoop of matcha and removing syrup can reduce sugar by more than 10 grams.
Use Custom Add-Ins to Boost or Balance
Starbucks lets you personalize almost anything on the menu, and the matcha latte oat milk is no exception. Use that flexibility to your advantage:
- Swap oat milk for almond milk to lower calories even further
- Add a shot of espresso for a matcha “dirty latte” with more caffeine and depth
- Choose iced over hot if you want a lighter drink with less steamed milk
- Ask for less ice to keep more flavor in the cup
- Try seasonal twists like lavender or strawberry—but keep those pumps to one or less
The goal isn’t to give up the flavor—it’s to make your drink fit your lifestyle. Once you understand what goes into the default order, it’s easy to build one that works for you.
