Oat Milk Coffee: The Ingredients
When making a perfect oat milk coffee, the ingredients play a huge role in creating a delicious and creamy drink. Start with your choice of coffee—whether it’s instant coffee, brewed coffee, or even cold brew or concentrate. I personally enjoy using 100ml strong coffee for a strong flavor, but if you’re after something a bit smoother, you can choose decaffeinated or instant espresso. For a real treat, you can go with 1-2 shots of espresso, especially if you have an espresso machine.
Now, the oat milk you choose is just as important. I prefer using 300ml unsweetened oat milk for its smooth texture, but you can go for sweetened oat milk if you like a sweeter taste. For those seeking something extra creamy, a barista blend will give you the thick, creamy consistency that makes a latte feel extra special. If you’re making your own, homemade oat milk works just as well, but store-bought options like vanilla oat milk can also add a nice touch of vanilla-ey flavor.
Next, you’ll need a sweetener to bring out the caramelly, floral, and woody notes. Maple syrup is my go-to, and just 1 tsp does the trick to add the perfect amount of sweetness. If you prefer something else, brown sugar, cane sugar, or even coconut sugar are great substitutes. You can also skip the sweetener entirely or use sugar alternatives if you’re watching your intake.
Finally, if you like your oat milk coffee a bit colder, ice cubes are optional. And for that extra dash of flavor, feel free to add a small amount of 1 tsp vanilla essence or ½ tsp vanilla extract—it really enhances the overall taste and makes the coffee even more delicious. No matter how you mix and match, the possibilities are endless, and the key is to experiment with your favorite ingredients to create the perfect cup.
How to Make Oat Milk Coffee
To begin, grab a gorgeous tall glass and pour in your freshly brewed coffee. If you want a little extra sweetness, add some maple syrup or brown sugar, then give it a good mix. While the coffee is settling, it’s time to focus on the oat milk. If you want it to be extra creamy, you’ll need to froth it. Start by pouring your cold oat milk into a separate mug and use a frother, or you can use a blender or immersion blender if you prefer. Another fun option is to use a mason jar—just pour in your oat milk, seal it tightly, and shake it up for a minute or two until it gets all frothy and foamy. If you like your coffee extra strong and black, you can skip the sweeteners and just enjoy it with the frothy oat milk on top.
Once the froth has settled, carefully pour it over the coffee, and don’t forget to top it with a little extra froth for a nice finishing touch. Stir gently to combine everything, and you’re ready to enjoy your oat milk coffee. If you want to get fancy, you can sprinkle a little cinnamon, cocoa, or even pumpkin pie spice on top for extra flavor. For those who prefer using instant coffee, simply mix the granules with boiled water, add a splash of vanilla, and pour in the frothy oat milk. Whether you’re using a microwave or stove to warm your milk, just make sure it’s steaming before you add it to your drink for that perfect texture. Taste it, adjust the sweetener if needed, and savor the delightful foam on top.

It’s truly become an obsession in my household, and I can’t wait to share it with you.
How to Froth Oat Milk with Coffee
When it comes to adding oat milk to your coffee, the texture is key to creating a smooth, creamy drink. I’ve tried several milk frothing methods to get the perfect foam, and I find that warm milk foams up much better than cold milk. If you don’t have a milk frother, you can still froth your oat milk using just a jar. Simply pour the milk into the jar, secure the lid tightly, and shake it vigorously for about 2 minutes. The shaking action will incorporate air into the milk, creating a light and airy foam that’s perfect for your coffee. If you’re using a blender, start at a low speed and gradually increase to high-speed for about 30 seconds. This method produces a nice, foamy texture as well, and the foam will be thicker compared to just shaking.
For those who prefer more control, I recommend using a handheld frother. This tool is a simple yet effective way to create a smooth, creamy foam. As you froth, tilt the frother to create a whirlpool effect—this helps the air flow evenly into the milk, making the foam richer. If you want to take things up a notch, try using a French press. Just add the oat milk and use the plunger to move the milk up and down until you get a foamy texture.
Another option is an immersion blender, which blends the milk to create a nice, foamy layer on top. Whisking the milk manually with a small whisk is also a great method, but it might take longer to get the foam you want. If you prefer a thicker foam, I suggest warming your milk before frothing, as this helps the texture and consistency. Whichever method you choose, you’ll be able to make the perfect frothy topping for your coffee.
Storage of Oat Milk Coffee
When making lattes with oat milk, it’s best to enjoy it fresh after you’ve made it. However, if you want to store it, I recommend turning it into an iced latte. Follow the instructions for making one, then pour it into an airtight container. You can keep it in the fridge for up to 4 days, but it’s important to note that it doesn’t keep as well for too long. So, make sure to enjoy it within that time frame to get the best taste!
Expert Tips for Making the Best Oat Milk Coffee
When making your oat milk coffee, the key is to ensure that every ingredient works in harmony to create a smooth, creamy drink. Start by selecting the right quality oat milk. Barista blend oat milk is an excellent choice since it froths well and blends perfectly with your coffee. Avoid overly flavored or unsweetened varieties unless you want to adjust the sweetness yourself. Also, remember that the proportions of coffee and milk are important—use a strong coffee brew or an espresso shot for a bold flavor, or choose instant coffee for a faster, milder version.
For the perfect texture, froth your milk properly. Using a milk frother will help you achieve a frothy and cloud-like consistency. You can tilt the glass slightly to help the frother work its magic, creating that smooth, creamy foam. Avoid over-heating the milk, as it can curdle and spoil the texture. If you’re after an iced oat milk latte, make coffee ice cubes by freezing brewed coffee in an ice tray to prevent your drink from becoming watery as the ice melts. For extra flavor, drizzle in maple syrup or a sprinkle of brown sugar for sweetness—just make sure they dissolve well when added to the hot coffee.
Don’t forget that everyone’s taste is different. You can adjust the strength of your coffee—whether it’s a weaker coffee or a stronger coffee for a more intense flavor. Experiment with different flavors, from pumpkin spice to gingerbread or hazelnut syrups, to give your drink a personalized touch. And if you prefer a milkier drink, add more milk to balance out the coffee’s richness. Whether you’re making a quick latte or a fancy iced latte, these tips will help you save time and money compared to going to a coffee shop—plus, you’ll get to enjoy the perfect vegan, dairy-free, and gluten-free coffee at home.
