I've always been a fan of experimenting with my morning coffee, and let me tell you, discovering the iced oat milk latte was a game-changer. It's creamy, delicious, and surprisingly easy to make at home. Gone are the days of queuing at coffee shops for that perfect cup.

With just a few ingredients and a couple of minutes, you can whip up this refreshing beverage right in your kitchen. Trust me, once you've tried making your own iced oat milk latte, you'll wonder why you ever settled for anything less. Let's dive into how you can create this delightful drink at home, shall we?

Benefits of Making Your Own Iced Oat Milk Latte

When I first ventured into making my own iced oat milk latte, the benefits were immediately clear. Not only did it become my morning ritual, but it also offered a handful of perks that made me question why I haven't started sooner. Here's why crafting this delightful beverage at home has become an integral part of my day.

First off, customisation is key. I get to control the sweetness and strength of my coffee precisely how I like it. Whether it's adding an extra shot of espresso for those particularly drowsy mornings or tweaking the amount of oat milk for the perfect creaminess, the power is in my hands.

Secondly, there's the undeniable aspect of cost savings. Coffee shop visits can quickly add up. By buying my ingredients in bulk, I’ve noticed significant savings. It’s quite satisfying to enjoy a cafe-quality latte without the cafe price tag.

Another major benefit is the health aspect. Making my own iced oat milk latte means I’m aware of every ingredient that goes into my cup. I can opt for organic coffee, sustainably sourced oat milk, and even skip on the preservatives and sugar that are often found in coffee shop versions. Plus, oat milk is a great dairy-free alternative that's low in fat and high in fiber, making it a healthier choice overall.

Last but by no means least, the environmental impact cannot be overlooked. By making my iced latte at home, I'm cutting down on disposable cup use and supporting sustainable dairy alternatives like oat milk. It’s a small step towards a more eco-friendly lifestyle that aligns with my values.

So, while the act of making my own iced oat milk latte might seem simple, the benefits it brings are both personal and impactful. It’s about more than just a beverage; it’s a choice that contributes to my well-being, wallet, and the planet.

Ingredients You'll Need

When I started experimenting with my iced oat milk latte at home, I quickly realised that simplicity is key. You don't need a plethora of ingredients to whip up this refreshing beverage. Here’s exactly what you’ll need to make your very own iced oat milk latte:

  • Espresso or strong brewed coffee: The foundation of any good latte. I usually go for a double shot of espresso for that rich, intense flavour. If you're using coffee, aim for a robust brew to mimic the espresso's boldness.
  • Oat milk: It’s creamy, it’s sweet, and it pairs beautifully with coffee. Oat milk is also a fantastic choice for those looking for dairy-free alternatives. Barista editions are my go-to since they’re formulated to froth and blend smoothly with hot beverages, but any oat milk will do the trick.
  • Ice cubes: To bring that refreshing coolness that’s perfect for warmer days or when you just need a chilled beverage.
  • Sweetener (Optional): Whether you're into classic sugar, honey, or perhaps a dash of maple syrup, this is completely up to your personal taste. I often find that the natural sweetness of the oat milk is enough for me.

Once you’ve gathered your ingredients, the assembly process is pretty straightforward:

  1. Brew your espresso or coffee: If opting for coffee, make sure it’s strong to ensure your latte doesn’t taste watered down once the ice and oat milk are added.
  2. Fill a glass with ice cubes: Use as many as you like. I usually fill the glass about halfway.
  3. Pour the espresso or coffee over the ice: Watching that coffee cascade over the ice cubes is one of those small pleasures in life.
  4. Top with oat milk: The amount is up to you, but I generally like a ratio of 2:1, coffee to oat milk.
  5. Add sweetener if using: Give it a good stir to make sure everything’s well combined.

And there you have it. With these simple steps and a handful of ingredients, you're well on your way to enjoying a delicious iced oat milk latte that's tailored just to your liking. Whether it’s the start of your day or a mid-afternoon pick-me-up, this latte is sure to hit the spot.

Step-by-Step Instructions

After gathering all the necessary ingredients for our iced oat milk latte, it's time to dive into the fun part - making it. I've broken down the steps below to ensure it's as straightforward as possible. Trust me, you'll whip up this refreshing drink in no time.

Preparing Your Coffee

  1. Brew the Espresso or Strong Brewed Coffee
  • Either use an espresso machine for a more authentic latte experience or a regular coffee maker for strong brewed coffee. You'll need about 60ml (2 ounces) of espresso or double that for coffee. Aim for a robust flavour to stand up against the oat milk.
  1. Let It Cool
  • Set the coffee aside to cool slightly. This prevents the ice from melting too quickly when you pour the coffee over it.
  1. Fill a Glass with Ice
  • Grab a tall glass and fill it to the brim with ice cubes. For something extra, try coffee ice cubes made in advance to keep your latte from getting watered down.
  1. Pour in the Coffee
  • Gently pour the cooled espresso or coffee over the ice. I find tilting the glass slightly helps distribute the coffee evenly without displacing too much of the ice.
  1. Top with Oat Milk
  • Pour oat milk over the coffee to your liking. I usually go for about 120ml (4 ounces), but feel free to adjust according to your taste preference.
  1. Optional Sweetener
  • If you're like me and enjoy a hint of sweetness, now’s the time to add your favourite sweetener. Stir well to combine everything beautifully.
  1. Give It a Final Stir
  • With a long spoon or straw, stir your iced latte to mix the coffee, oat milk, and sweetener together. This ensures every sip is perfectly balanced.

Remember, this iced oat milk latte is versatile. Whether it's a morning pick-me-up or an afternoon treat, it's always a delight. Feel free to tweak the recipe to suit your taste and enjoy the process of making your perfect cup.

Tips for the Perfect Iced Oat Milk Latte

Crafting the perfect iced oat milk latte isn't just about mixing coffee and oat milk. It's an art that combines the right technique with quality ingredients. I've gathered some top-notch tips that'll elevate your homemade latte to rival any cafe creation. Trust me, with a little attention to detail, you'll be sipping on a delightfully refreshing beverage that effortlessly blends rich coffee with the creamy texture of oat milk.

First off, the quality of your coffee matters. For a truly profound base, opt for freshly ground coffee beans for your espresso or strong coffee. The freshness adds a vibrancy to your latte that pre-ground coffee can't match. If you're brewing espresso, aim for a rich and bold shot. For those using strong coffee, a French press or Aeropress works wonders in extracting those deep, complex flavors you want as a foundation.

When it comes to oat milk, not all brands are created equal. Some are creamier and blend more seamlessly with coffee, while others can separate or offer a less desirable taste. Experiment with a few to find your favorite. Bear in mind, barista editions are formulated specifically for coffee, providing that silky texture and stability when mixed with acidic components like coffee.

Ice is more important than you might think. Always use plenty of ice to ensure your latte stays cold and refreshing without watering down too quickly. The trick is to fill your glass to the brim with ice before adding your coffee and oat milk. This way, your latte maintains its integrity from the first sip to the last.

Sweeteners and flavors can transform your latte. Whether you swear by simple syrup, have a penchant for vanilla extract, or lean towards a touch of caramel, adding sweeteners or flavors should be done with a light hand. You want to enhance, not overpower, the delicate balance of your latte. Start with a small amount and adjust according to your taste.

By keeping these tips in mind, you're well on your way to mastering the art of the iced oat milk latte. It's all about experimenting and finding what works best for you. Whether you're adjusting the coffee strength, trying different oat milk brands, or playing with sweeteners, each variation brings you closer to your ideal version of this contemporary classic.

Enjoy Your Homemade Iced Oat Milk Latte

After mastering the art of selecting the right ingredients and understanding the essence of a flawless brew, I'm ready to guide you through the actual process of making your own iced oat milk latte. Trust me, it's simpler than you might think, and the end result is utterly rewarding.


  • Freshly ground coffee beans
  • Cold water
  • Oat milk
  • Ice cubes
  • Optional: Sweetener or syrup of choice


  1. Brew Your Coffee: Start by brewing your coffee. I prefer to use a French press for its rich flavour, but any method you're comfortable with will do. Use about 2 tablespoons of coffee per cup of cold water. Once brewed, allow the coffee to cool slightly.
  2. Prepare the Glass: Fill your serving glass to the brim with ice cubes. This not only cools the drink but also preserves its texture and integrity.
  3. Mix: Pour the cooled coffee over the ice. I usually aim for about 200ml of coffee, leaving room for the oat milk.
  4. Add the Oat Milk: Slowly pour oat milk into the glass. The beauty of oat milk is its creamy texture, which beautifully complements the coffee. Adjust the amount according to your taste; I recommend starting with about 80ml and adjusting from there.
  5. Customise: Here’s where you can get creative. If you prefer your latte sweetened, add a dash of your favourite syrup or sweetener. Vanilla syrup or a pinch of cinnamon works wonders for me.
  6. Stir and Enjoy: Give your latte a gentle stir to mix all the ingredients. And there you have it, your perfect iced oat milk latte, ready to be savoured.

Remember, the key to an exceptional homemade iced oat milk latte lies in patience and willingness to experiment. The more you tweak and fine-tune your recipe, the closer you'll get to crafting a drink that’s uniquely yours. Whether it’s adjusting the coffee-to-milk ratio or exploring different sweeteners, each variation opens the door to new flavours and experiences.
