How to Make Oat Milk Matcha Horchata

In a small pot over medium heat, combine oat milk, a cinnamon stick, cane sugar, and vanilla paste. Stir occasionally and bring to a gentle boil. Once boiling, turn off the heat and let the mixture sit to cool slightly.

While the horchata base is cooling, add the sifted matcha powder to a small mixing bowl or cup. Pour in the hot water and whisk vigorously using a matcha whisk or frother until the matcha is smooth and fully dissolved.

Grab a tall glass and fill it with ice cubes. Pour the matcha mixture over the ice. Then, slowly pour about 1½ cups of the room temperature oat horchata mixture over the matcha. Stir gently to combine.

Sip and enjoy your creamy, earthy, cinnamon-kissed creation!

Commonly Asked Questions

Can I use a different plant milk?

Do I have to use a cinnamon stick?

Nope. You can sub ¼ teaspoon of ground cinnamon if that’s what you have.

What kind of matcha should I use?

Ceremonial-grade matcha gives the best color and flavor, but culinary grade works for an everyday version.

Can I make this in advance?

Yes! Store the oat milk horchata and matcha mix separately in the fridge for up to 2 days. Combine just before serving for best results.
