What is an Iced Matcha Latte with Oat Milk?

An Iced Matcha Latte with Oat Milk is a refreshing and creamy beverage made by combining matcha powder, oat milk, and ice. The matcha powder is whisked with a small amount of hot water to create a smooth paste, then mixed into oat milk and poured over ice.

The result is a vibrant green, chilled, and flavorful drink and is almost as easy to make as an Americano!

This drink offers a balance of earthy matcha flavors, the creaminess of oat milk, and the cooling sensation of the ice. The result is delicious and invigorating. Plus, it’s an excellent alternative to caffeinated Matcha Coffee.

Tons of Health Benefits

The combination of matcha and oat milk is rich in antioxidants, vitamins, and minerals. It’s such a refreshing drink you can almost forget it’s healthy!

Plant-Based and Vegan Friendly

Oat milk is a great option for those looking for a plant-based milk and are on vegan diets. So, this latte is a cruelty-free and sustainable option.

Less Caffeine

The best part about matcha is the actual matcha powder does not have much caffeine, but it still provides a sense of alertness to get you through the mid-day slump.

This is perfect for those fellow coffee drinkers who had to switch to decaf coffee due to the high caffeine content in a regular cup of joe.

Matcha is an excellent choice for those with caffeine sensitivities who still need a boost of focus throughout the day.

Ingredient Notes

  • Matcha Powder – When purchasing matcha powder, look for a vibrant green color, which means it’s a high-quality matcha powder. You could stick to pure powdered Japanese green tea or buy a pre-sweetened latte mix. 
  • Hot Water – It doesn’t need to be boiling, but warm water makes it easier to dissolve the matcha.
  • Oat Milk – Any oat milk will work, but barista-style oat milk will give the beverage a thicker, creamier, more indulgent texture.
  • Sweetener (optional) – If you’re using a pre-sweetened matcha latte mix, you don’t need to add any sweetener. However, if you’re using pure ceremonial matcha, it’s recommended to use a liquid sweetener.  Honey, agave, or date syrup will easily dissolve into your iced drink. 
  • Ice cubes

  • Whisk or Handheld Frother – You’ll need a small whisk or handheld milk frother to dissolve the matcha mixture in the hot water. A small fork will work in a pinch. 
  • Lidded Jar (Optional) – I recommend combining the ingredients in a lidded jar. This way, you can give it a vigorous shake to incorporate the matcha into the thick oat milk fully. 
  • Drinking Glass – Whatever vessel you’d like to sip your new favorite green drink from. If you’re on the hunt for some of the best glasses, we’ve listed a few of our favorite double walled glasses here, which are great for keeping iced drinks nice and cold!

Easy Instructions 

  1. Create the matcha paste. Whisk together the fine powder and hot water in a small bowl until it forms a smooth paste.
  2. Shake it all to combine. Add the oat milk, optional sweetener, and matcha paste to a lidded jar. Screw on the top and shake vigorously until the matcha is well incorporated into the milk.
  3. Assemble. Add ice cubes to your drinking glass. Then, pour the frothy matcha latte mixture over the top.
  4. Tweak and serve. Taste and adjust the sweetness or matcha intensity as necessary.

Tips and Tricks

  • If you don’t have a mason jar or airtight container handy you can always add all ingredients to a drinking glass and stir to combine. However, this method doesn’t result in the same frothy texture. When in doubt, you can always use a milk frother as well to get the similar frothy texture.
  • Get creative and customize your drink with additional flavors is the best way to enjoy this beverage. For example, add vanilla extract to boost sweetness or a sprinkle of cinnamon for a warming effect.

  • If you use a granulated sweetener instead of a liquid one (like agave nectar or simple syrup), incorporate it along with the hot water and matcha powder to dissolve it. This way, you won’t end up with a mouthful of grainy sugar. 
  • Try adding a flavored coffee or cocktail syrup to your cup to create exciting and tasty variations of the classic matcha latte or even opt for a teaspoon of maple syrup. Matcha and pistachio are one of my all-time favorite combinations that really amp up this iced matcha latte recipe.

Is oat milk good for a matcha latte?

Oat milk is a popular non-dairy milk of choice for making matcha lattes and typically yields the best results. It has a creamy texture and a slightly sweet, nutty flavor that compliments the earthy taste of matcha.

Is matcha still healthy with oat milk?

Matcha is packed with antioxidants and amino acids. Pair that with oat milk that’s fortified with nutrients like calcium, vitamin D, and vitamin B12, and you can enjoy a tasty and nutritious beverage – which is on the healthier side than most sweet Starbucks drinks you’ll find these days!

What milk tastes best with an iced matcha latte?

Any matcha lover will tell you the choice of milk for an iced matcha latte ultimately comes down to personal preference. An iced matcha latte benefits from slightly sweeter milk because of the earthy flavor of matcha. Oat milk or cashew milk are excellent options because they have sweet undertones and add body and a nutty creaminess to the drink or if you prefer regular milk, try adding whole milk! Or if you’re looking for a “skinny” version of this drink, try using nonfat milk like what was used in our version of the Starbucks Skinny Vanilla latte recipe.
