“Good coffee is like friendship: rich, warm, and always welcome.” – Anonymous
Whether you’re vegan, lactose-intolerant, or simply love the nutty sweetness of oat milk, mastering this recipe means you’ll never have to leave your house for a quality caffeine fix again. Let’s dive in.
Step-by-Step Guide to Making a Creamy Oat Milk Latte
Learning how to make a creamy oat milk latte at home isn’t just a fun kitchen experiment—it’s a skill that offers flexibility, control over ingredients, and savings over time. Below, you’ll find a comprehensive breakdown to achieve that smooth, frothy, barista-style texture every single time.
Ingredients You’ll Need
To make a proper oat milk latte, quality ingredients are non-negotiable. Here’s your basic list:
1 shot of espresso (or ¼ cup strong brewed coffee)
½ to ¾ cup of oat milk (preferably barista edition)
Optional: vanilla extract, maple syrup, or cinnamon
A pinch of sea salt (to enhance the milk’s natural sweetness)
Tools and Equipment
While a full espresso setup is ideal, you can still make a solid oat milk latte with more common kitchen tools.
| Tool | Why It Matters |
|---|---|
| Espresso machine / Moka pot / French Press | Extracts strong, concentrated coffee |
| Milk frother / Steam wand / French press | Froths oat milk to creamy perfection |
| Thermometer (optional) | Helps hit the ideal frothing temperature (55–65°C) |
| Tall mug / Latte glass | Enhances presentation and temperature retention |

Brewing Your Espresso or Coffee Base
The base of any great latte is its coffee. If you have an espresso machine, pull a shot using fresh, finely ground beans. If not, a moka pot or Aeropress will do the job. You want a strong, rich flavor that can balance out the creaminess of oat milk.
“The best coffee is black as the devil, hot as hell, pure as an angel, sweet as love.” – French Proverb
Tips for a strong base:
Use a dark roast or medium-dark roast for boldness.
Grind your coffee beans just before brewing for maximum aroma.
Maintain a water temperature around 90–96°C to avoid over-extraction.
Frothing Oat Milk the Right Way
This is the moment of truth. Frothing oat milk can be a bit trickier than cow’s milk due to its lower protein content—but barista-grade oat milk is a game changer.
Key Frothing Tips:
Heat your oat milk to around 140–150°F (60–65°C). Too hot? It separates.
Use a hand frother, electric frother, or French press to create foam.
Froth until it reaches a silky, microfoam texture—no large bubbles!
If you’re using a steam wand, keep the tip just below the surface for the first 5 seconds, then submerge slightly to incorporate air. If you’re using a French press, pump the plunger up and down vigorously for 30–40 seconds until it’s frothy.
Putting It All Together: Latte Assembly
Now comes the most satisfying part—bringing your latte to life.
Pour your espresso or strong coffee into a preheated mug.
Gently swirl your frothy oat milk to unify foam and liquid.
Slowly pour the milk over the coffee, holding back the foam with a spoon.
Spoon the foam on top and finish with a sprinkle of cinnamon or cocoa.

Choosing the Best Oat Milk for Lattes
Not all oat milks are created equal—some are too watery, while others may curdle or separate under heat. Here’s how to choose the best oat milk for your latte game.
What Makes Oat Milk Creamy?
Creaminess in oat milk comes from a balance of:
Oats-to-water ratio
Added fats (often sunflower oil)
Starches and beta-glucans that thicken the texture
The ideal oat milk for lattes mimics the body of whole dairy milk without overpowering the espresso’s flavor.
Store-Bought vs. Homemade Oat Milk
| Feature | Store-Bought (Barista) | Homemade |
|---|---|---|
| Texture | Creamy, froths well | Thinner unless fortified |
| Taste | Balanced | May taste more “raw” or bland |
| Stability | Heat and froth stable | Prone to separation |
| Convenience | Ready to use | Requires soaking, straining, blending |
Flavor Variations to Try at Home
Now that you’ve mastered the classic oat milk latte, why stop there? The beauty of homemade lattes lies in creative freedom—you can flavor and adapt them to suit your preferences, moods, or even the season. At Lyoncafe, we’ve experimented with dozens of combinations across our coffee bars in both urban cafés and rural escapes—and here are the crowd favorites.
Vanilla, Cinnamon, and Maple Touches
Adding a subtle sweetness or spice can completely transform your oat milk latte. Try these variations:
Vanilla Oat Milk Latte: Add ¼ tsp of pure vanilla extract or use vanilla oat milk.
Maple Cinnamon Latte: Stir in 1 tsp of real maple syrup and a dash of ground cinnamon.
Salted Caramel Oat Latte: Add ½ tbsp caramel sauce and a tiny pinch of sea salt for depth.
At Lyoncafe, our “Golden Autumn Latte” combines oat milk, maple, cinnamon, and a splash of vanilla—offered every fall since 2019, it remains a customer favorite and a signature of our warm, welcoming culture.
Iced Oat Milk Latte Version
Hot days? No problem. Iced oat milk lattes are refreshingly smooth and perfect for summer sipping. Here’s how:
Brew a double shot of espresso or ½ cup strong coffee.
Chill it or pour it directly over ice.
Froth cold oat milk using a handheld frother or shake vigorously in a mason jar.
Pour oat milk over the coffee and stir.
Mocha or Matcha Oat Milk Lattes
Why stick to plain when you can go bold? Oat milk is versatile enough to handle deeper flavors like chocolate and matcha.
Mocha Oat Milk Latte: Add 1 tbsp of unsweetened cocoa powder or a shot of chocolate syrup.
Matcha Oat Milk Latte: Whisk 1 tsp of ceremonial-grade matcha with a bit of hot water, then blend with steamed oat milk.
Both are antioxidant-rich and full of flavor. Matcha also adds calm energy thanks to L-theanine, making it a favorite for mindful mornings.
Why Choose Oat Milk? (Nutrition and Sustainability)
With so many plant-based options—almond, soy, coconut, and cashew—why is oat milk standing out?
The answer lies in its balance between taste, texture, health benefits, and environmental responsibility.
Health Benefits of Oat Milk
| Benefit | Explanation |
|---|---|
| Lactose-free | Safe for those with lactose intolerance |
| High in beta-glucans | Helps lower cholesterol and supports heart health |
| Naturally sweet | Requires less added sugar |
| Vegan and nut-free | Ideal for people with multiple dietary restrictions |
A cup of fortified oat milk typically provides:
2–3g of protein
120 calories
Calcium and Vitamin D (if store-bought)
Environmental Impact Compared to Dairy
Oat milk isn’t just good for you—it’s better for the planet.
According to a 2022 report by the University of Oxford:
Oat milk produces 80% fewer greenhouse gases than cow’s milk.
Requires 60% less land and 70% less water than almond milk.
As a brand, Lyoncafe sources its oat milk from certified sustainable producers and encourages customers to use reusable cups through incentive programs—a part of our Zero Waste 2030 initiative.
Frequently Asked Questions About Oat Milk Lattes
We’ve served over 2 million oat milk lattes across our Lyoncafe branches—and here are some of the most asked questions from curious drinkers like you.
Can I use instant coffee instead of espresso?
Yes. While espresso delivers a stronger, more complex flavor, high-quality instant coffee can work well. Choose one labeled as freeze-dried Arabica and brew it strong for the best results.
Can I froth oat milk without a frother?
Absolutely. Here are three methods:
French Press: Pour heated oat milk and pump the plunger vigorously.
Whisk: Use a wire whisk and some elbow grease.
Jar Shake: Shake heated milk in a tightly sealed mason jar (use a towel to avoid burns).
Is oat milk better than almond or soy for lattes?
In terms of texture and flavor, yes. Oat milk has a neutral, slightly sweet taste that blends beautifully with coffee. Almond milk tends to be watery and separates easily, while soy milk may have a more beany aftertaste.
