Ingredients for Iced Matcha Latte with Oat Milk

To prepare this invigorating Iced Matcha Latte, quickly gather the following ingredients:

  • Matcha powder: Matcha powder is the star ingredient of this latte, providing vibrant green color and a unique flavor profile. Select a ceremonial-grade matcha for the best flavor.
  • Hot water: Hot water helps to dissolve the matcha powder better than cool or cold water, ensuring a smooth base for the latte.
  • Sugar: A touch of sweetness from sugar helps to balance the earthy and slightly bitter notes of matcha, creating a harmonious flavor profile. You can adjust the amount of sugar according to your taste preferences or use alternative sweeteners if preferred. If you have flavored syrups on hand, vanilla syrup would also taste great (just skip the optional vanilla extract if using).
  • Ice cubes: Ice cubes rapidly cool down the matcha mixture and create a refreshing and chilled base for the latte. If you have either matcha/ green tea ice cubes or plant-based milk ice cubes, feel free to use those. There’s enough flavor from the matcha and oat milk that you don’t need to worry about the ice watering down this drink.
  • Oat milk: Oat milk adds a creamy and velvety texture to the latte while maintaining a neutral flavor that complements the matcha. Other plant-based milk options can work as well, but this recipe was designed specifically for using oat milk.
  • Vanilla extract (optional): Offering a subtle hint of warmth and sweetness to the latte, vanilla extract enhances the overall flavor profile and adds a delightful aromatic element. While optional, vanilla extract can really elevate the taste of your iced matcha latte.

How to Make an Iced Matcha Latte with Oat Milk

In just a few minutes you’ll make and enjoy this iced oat milk matcha latte. Follow the steps below and you can create the perfect drink every time!

Step 1: Whisk Matcha and Sugar

Start by boiling water. As your water heats up, add your matcha powder to a very large glass.

Once the water has boiled, remove it from heat and let it cool for a few seconds until the bubbles subside. Pour ⅓ cup of hot water over your matcha powder.

Using a handheld frother or whisk, vigorously mix your matcha and water until the powder is completely dissolved, leaving behind no clumps.

Next, add the sugar to the mixture and mix until fully dissolved.

Step 2: Add Other Ingredients and Serve

If you desire a subtle hint of vanilla (like I always do), incorporate ¼ to ½ teaspoon of vanilla extract into the glass and give it a gentle stir.

Next, add ice cubes to the glass and stir to combine. This will rapidly cool down the hot matcha mixture and create a refreshing base for your latte.

Finally, pour oat milk into the glass, letting it cascade over the ice and swirl through with the matcha. Give a final stir to ensure all the flavors are beautifully integrated and your latte has a consistent soft green color.

Your iced matcha latte with oat milk is now ready to enjoy! Sip it slowly, relishing the invigorating flavors and the soothing creaminess.

Iced Matcha Latte Variations

There are a few easy ways to modify this recipe to make it uniquely your own. If you’re interested in experimenting, I suggest trying a:

  • Sweetener Swap: Substitute the sugar with alternative sweeteners such as maple syrup, agave syrup, or stevia. Just note that these will all create different flavor profiles and I recommend starting with granulated sugar the first time you make it.
  • Creamy Twist: Experiment with different plant-based milks like almond milk, coconut milk, or soy milk. I typically make iced vanilla matcha lattes with soy milk.
  • Matcha Modification: Adjust the matcha powder quantity according to your taste preferences. Increase or decrease the amount to achieve your desired matcha flavor intensity.

How to Store Leftover Oat Milk Iced Matcha Latte

This recipe makes a single serving but, if you find yourself with leftover iced matcha latte, place your glass into the fridge for up to 24 hours. Keep in mind that the drink's texture may change slightly upon refrigeration. To restore the original consistency, give it a gentle stir before consuming.
