How to Make a Matcha Latte with Oat Milk at Home. A matcha latte has become a favorite drink among many due to its smooth, earthy taste and numeroushealth benefits. When paired with oat milk, it becomes creamy, dairy-free, and naturally sweet. The best part? You don’t need to head to a café to enjoy it—you can easily prepare a matcha latte with oat milk at home in just a few minutes.
This guide will walk you through everything you need to know: from the ingredients you’ll need to the step-by-step process of making the perfect cup.

Why Choose Matcha and Oat Milk?
Matcha is finely ground green tea powder that is packed with antioxidants, especially catechins, which support metabolism, energy, and overall wellness. Unlike regular green tea, you consume the entire leaf when drinking matcha, which means you get even more nutrients.
Oat milk, on the other hand, is a plant-based alternative that adds a creamy texture and subtle sweetness without overpowering the delicate flavor of matcha. It’s also a great choice for those who are lactose-intolerant or simply want a vegan-friendly option.
Ingredients You’ll Need
To make a delicious oat milk matcha latte at home, gather the following:
- 1 teaspoon high-quality matcha powder
- 2–3 ounces hot water (not boiling, about 175°F / 80°C)
- 1 cup oat milk (barista-style oat milk works best for frothing)
- Sweetener of choice (optional): honey, maple syrup, or agave
Step-by-Step Instructions
1. Sift the Matcha Powder
Matcha tends to clump, so it’s best to sift it into a small bowl before whisking. This ensures a smoother, lump-free drink.
2. Add Hot Water
Pour 2–3 ounces of hot (not boiling) water over the matcha powder. Water that’s too hot can make matcha taste bitter.
3. Whisk Until Frothy
Using a bamboo whisk (chasen) or a handheld frother, whisk the mixture in a zigzag motion until small bubbles form and the matcha is smooth and frothy.
4. Heat and Froth the Oat Milk
Warm your oat milk on the stove or in a microwave until hot, but not boiling. If you have a frother, use it to create a creamy foam that mimics a café-style latte.
5. Combine and Sweeten
Pour the frothy oat milk into the matcha mixture. Stir gently and add sweetener if desired. Taste and adjust according to your preference.
Benefits of Matcha latte with oat milk.
A matcha latte with oat milk is a powerhouse of wellness benefits, combining the antioxidant-rich properties of matcha with the creamy, nutrient-dense qualities of oat milk. Matcha provides a sustained energy boost without jitters thanks to its natural caffeine paired with L-theanine, which promotes calm focus and mental clarity. It’s also packed with catechins, particularly EGCG, known for supporting metabolism, detoxification, and heart health. Oat milk, on the other hand, is naturally lactose-free, rich in beta-glucans that help lower cholesterol, and provides essential nutrients like fiber, B vitamins, and iron. Together, they create a gut-friendly, heart-healthy, and dairy-free drink that supports energy, focus, and overall wellness in a smooth, delicious way.
Tips for the Perfect Matcha Oat Milk Latte
- Choose high-quality matcha: Bright green, ceremonial-grade matcha gives the best flavor and health benefits.
- Use barista-style oat milk: It’s designed to froth better and makes your latte creamier.
- Experiment with flavors: Add a pinch of cinnamon, vanilla extract, or even a drop of almond extract for a twist.
- Serve hot or iced: For iced matcha oat milk latte, simply whisk the matcha with water, then pour over ice before adding cold oat milk.
