What is an oat milk cappuccino?
An oat milk cappuccino is an espresso-based beverage made with oat milk.
It has become increasingly popular in recent years due to its creamy and nutty flavor, which is similar to cow’s milk but without dairy.
Oat milk cappuccinos are typically vegan and lactose-free, and you can often find them on the menu of specialty coffee shops.
But today, you don’t have to go out to get your caffeine fix. This easy-to-make oat milk cappuccino recipe might be even better than the coffee shop equivalent!

What does an oat milk cappuccino taste like?
An oat milk cappuccino has a unique taste that could be described as earthy, creamy, and nutty.
It’s much smoother than other non-dairy milks and has an incredibly thick foam that’s perfect for the traditional cappuccino experience.
The flavor of oats pairs exceptionally well with espresso, providing a truly unique flavor profile that can be either subtle or bold, depending on the type of beans used to make your cappuccino.
Oat milk also naturally adds sweetness to your drink, eliminating the need for extra sugar or flavored syrups; however, you can add a touch of flavor if desired.

Which ingredients are needed for this recipe?
For this delicious recipe, you’ll only need two main ingredients:
- Oat milk
- Espresso coffee
You can customize this cappuccino to your taste by adding various sweeteners and other add-ons. I’ll go into more detail about this later on.
Does oat milk froth well for a cappuccino?
Oat milk is naturally creamy, and many barista-style versions are made to steam smoothly, which helps it trap air and build a thicker foam.
That's why oat milk is a popular choice for cappuccinos and latte art.
Another significant benefit of using oat milk to make a great cappuccino is that oats naturally have sweet notes in their flavor profile.
It also helps bring out some sweetness in espresso shots, making them taste even better than they would otherwise.

With the right steaming (or frothing) technique, oat milk can give you that fluffy microfoam that makes a cappuccino feel like a real coffee-shop drink.

Which coffee is best used for this cappuccino?
For this cappuccino, it’s best to use espresso coffee. You can make espresso using an espresso machine, a Moka pot, an AeroPress, or even your Nespresso or Keurig machine.
In this article, you can check out the best Nespresso coffee pods for cappuccinos! If you prefer using coffee beans, you can select your favorite roast.
For their intense flavor, espresso is typically made with medium or dark-roasted coffee beans.

But because oat milk is naturally sweeter than dairy milk, a lighter roast can also be used.
Blonde espresso tastes delicious in this recipe, depending on the desired strength.

How do you sweeten this cappuccino?
When it comes to sweetening an oat milk cappuccino, there are several approaches you can take.
First, you could add a natural sweetener, such as honey or maple syrup, directly to the cappuccino. Not only will this bring some sweetness, but also a unique flavor as well.
You can also experiment with adding flavored syrups, such as vanilla or brown sugar, for even more flavor and sweetness options.

If you want to keep it classic, you can add some cocoa powder or cinnamon powder to the top:

Or try adding some dark chocolate shavings on top. They will melt into the cappuccino as you drink it!
Now that you know about the various ways you can customize this drink, you can put it to the test by following the oat milk cappuccino recipe below:
