When it comes to using oat milk, my favorite recipes to make are ice cream, smoothies, and this oat milk latte.

Over the past few months, I’ve had to cut dairy out of my diet. While I love foods that contain dairy, my body is not a fan and I find myself breaking out. To combat this, I’ve had to make a fair few changes to my daily food habits.

Initially, I was a little skeptical about swapping out my standard dairy products for non-dairy counterparts. I’ve often heard that they don’t taste as good as they are often more expensive too. As someone who drinks multiple lattes a day, I had to find an alternative. While I can say that I was not a fan of soy milk or lactose free milk, I found a new obsession with oat milk!

Unlike other plant based milks, oat milk has a natural sweetness and creaminess, something I find lacking in most kinds of milk. It tastes great with cereal or even on it’s own, but I really love it with my coffee! As such, I’ve been meaning to share an oat milk latte recipe for quite some time. It’s been a savior since I’ve cut dairy out of my diet, and honestly, I prefer it to normal lattes! It needs just two ingredients and can be made three ways!

No dairy and no sugar are needed, but you’d never tell. The texture is smooth, creamy, and a light froth on top. It’s naturally sweet and pleasantly bitter, without being overpowering.

I love inviting my friends over for coffee and making them homemade oat milk lattes- They love how easy it is AND it saves them over $5 a pop each time. In fact, they said it was better than Starbucks and Dunkins!

Ingredients to make an oat milk latte

  • Espresso OR brewed coffee: I prefer using espresso, as you can adapt it as to how many servings you will make. However, freshly brewed coffee can also be used. You will need to adjust the strength based on personal preference.
  • Oat milk: Barista blend/edition of oat milk. This gives the lattes an even creamier texture, and easy crema on top (the dark froth on top). If you can’t find any barista blends, standard oat milk will be fine.
  • Sweetener of choice: Optional, but only add it if you prefer a sweet latte.

How do you make an oat milk coffee?

There are three ways to make this latte. While I prefer using the coffee machine, I understand not everyone has one. You can also use the stovetop or even the microwave!

Coffee machine

Start by brewing two shots of espressos in two coffee mugs or glasses. Next, pour your milk into the metallic milk jug and steam the milk until it reaches 55C/130F. Lightly invert the jug at a slight angle to create a thin form.

Now, use a spoon to hold back the foam and pour the warm milk over the espresso shots. Spoon out the froth on top.


Pour your milk into a small saucepan and place over medium heat. Once it begins to simmer, remove it from the heat and whisk vigorously, to create a form.


Place your oat milk into a sealable glass jar. Shake it vigorously, until the milk becomes frothy and it doubles in size. Remove the lid and microwave for a minute, or until a froth appears on top.

What is the difference between standard oat milk and barista oat milk?

Standard oat milk and barista oat milk are both a little bit different. The former is perfect to use as you would with traditional milk (cereal, baking, oatmeal, etc). The barista blend can also be used for all of that but has also been formulated to be able to steam and heat better, and perfect for coffee-based beverages.

Can I make this an iced oat milk latte?

To make an iced oat milk latte, simply pour the espresso over ice, and omit warming up the milk. Instead, pour cold oat milk over the top and enjoy.

Alternatively, you can make a double or triple serving and refrigerate it all in a jug and keep it for when the coffee craving strikes!

Tips to make the best oat milk coffee

  • If you use instant or freshly brewed coffee, be sure it is very strong. 1/2 cup (125 ml) of freshly brewed coffee is enough for 2 oat milk lattes.
  • If you can’t tolerate caffeine, caffeine free espresso and coffee can be used.
  • Use a thermometer to gauge the temperature of the milk when steaming it. The perfect temperature is 55C/130F, however, if you prefer an extra hot latte, you can allow it to reach 62C/144F.
  • Not all oat milk is created equal. Some can be quite flavorless and watery, and lose their natural sweetness once heated up. If your oat milk is sweet and creamy BEFORE in its room temperature/chilled state, it should maintain all the flavor and creaminess once heated.

Oat milk coffee variations

Not a fan of lattes? Oat milk works in every single coffee beverage out there. Here are some ideas to try-

  1. Cappucino: Equal parts steamed milk and froth.
  2. Flat white: Omit the froth and increase the steamed milk.
  3. Macchiato: Omit the steamed oat milk and instead, double the amount of foam on top.
  4. Cafe au lait: Just a few tablespoons of the steamed oat milk.
  5. Mocha: Use chocolate flavored oat milk and make the latte as instructed.
