Why This Recipe is So Good
The great thing about making drinks at home is that you have complete control over the ingredients as well as the sweetness. This iced brown sugar matcha latte is less sweet than Starbucks. But the brown sugar syrup recipe makes enough for 3 drinks, so you can add as much or as little sweetener as you desire.
Adding a little bit of this homemade brown sugar syrup to your daily matcha latte is such an easy way to upgrade your morning ritual. It’s made with water, brown sugar and vanilla bean paste, then simmered so all those wonderful, rich, molasses-y brown sugar and vanilla flavors become one. Even without the vanilla cold foam – a brown sugar oatmilk matcha latte is my number 1 go-to drink.
Recipe Ingredients
- Matcha powder – Ceremonial grade matcha powder is the best to use for matcha lattes and other drinks. This high-quality matcha powder has a bright green color and a smooth, grassy flavor. Culinary matcha powder can have a bitter flavor to it and because of that, it’s best reserved for baking and cooking.
- Brown sugar syrup – This simple syrup is made with brown sugar, vanilla bean paste and water. It’s sweet, molasses-y, and quick to make. It’s used to sweeten the matcha latte and the vanilla cold foam.
- Vanilla cold foam – Oat milk, heavy cream, and a little bit of the vanilla brown sugar syrup is whisked until foamy and delicious then poured over the matcha latte.
- Oat milk – Oat milk is very creamy, delicious, and similar to dairy milk. This one from Califa Farms is my favorite. However, you can swap it out for almond milk, soy milk or even coconut milk if you prefer.
How to Make an Iced Brown Sugar Matcha Latte with Vanilla Cold Foam
All ingredients, measurements, and instructions are in the recipe card at the bottom of this post.



Make brown sugar syrup
Add brown sugar, water and vanilla bean paste to a small sauce pot. Heat on medium-low until the brown sugar is melted, about 10 minutes. Remove from the heat then allow it to cool.
Make vanilla brown sugar matcha latte
In a matcha bowl, add matcha powder and warm water. Use a bamboo matcha whisk to stir the matcha until combined and frothy. If using a bamboo whisk, stir in a “M” pattern until frothy. Don’t overly whisk the matcha; we don’t want too much foam.
Stir in 2 teaspoons of the brown sugar syrup then set aside. Add oat milk to the glass along with the prepared matcha and ice cubes.
Make vanilla bean cold foam
In a small cup, add heavy cream, milk and 1 teaspoon of brown sugar syrup. Use an electric milk frother to whisk until combined and foamy. Pour vanilla cold foam slowly over your matcha latte and enjoy.


Tips and Tricks
- How do you get the foam to stay on top? Don’t whisk the matcha too much, just whisk until the matcha is combined with the water; otherwise, the matcha foam will swallow up the cold foam and everything will just blend together. Add matcha to the cup, ice, then slowly pour over the cold foam.
- Cold foam not whipping up right? Make sure you are using heavy whipping cream; its high fat content is vital for whipping up a nice and thick cream. Or it could be your batteries. My milk frother was struggling to whip the cold foam into a stable foam but once I replaced the batteries, it worked perfectly and the foam was chef’s kiss.
