❤️ Why you will love this recipe
- Easy: This delicious latte couldn’t be easier. All you have to do is make espresso or strong coffee, mix it with your sweetener of choice if desired, pour it over ice, add oat milk, stir, and enjoy!
- Quick: It’s ready in 5 minutes, including making the coffee.
- Simple ingredients: The base ingredients for this recipe are coffee, ice, and oat milk. You can also add a sweetener like a maple syrup, or flavorings, but they’re not really necessary.
- Cheap: Homemade oat milk coffee recipes cost less than a dollar or pound to make. It’s so much cheaper than ordering at a local coffee shop.
- Healthier coffee: Because you can control things like sugar when making it yourself, this oat milk latte recipe is a great addition to a healthy diet! It’s also low-carb, gluten-free (check the oat milk brand first!), and has a little extra fiber compared to whole milk: 0.8g per 100ml as opposed to 0g.
🗝️ Key Ingredients & Substitutions
- Coffee: Medium-roast coffee beans have the best flavor for this cold coffee drink. I made my French Press Espresso recipe to make a couple of espresso shots. This recipe is the easiest way to make espresso without a machine and is so handy for making fancy coffee drinks at home. If you have an espresso machine that would be another great option, or even a stovetop espresso maker (moka pot). In a pinch, you can add a teaspoon of instant coffee to 1/3 cup of boiled water to make strong coffee. It works well as an espresso replacement. Cold brew coffee would also work really well as it’s already quite strong.
- Oat Milk: Oat milk is plant-based milk made of oats with a slightly nutty flavor. It’s super creamy in flavor and texture, and a great substitute for regular milk. For best results, use a “barista” version of this milky drink. It is creamier than regular and froths really well too, similar to dairy milk. Oatly is my favorite brand of oat milk, especially their grey barista carton. No affiliate links here, it’s just the oat milk that I love the most. If you make your own oat milk at home, that should be good in this recipe as well.
- Ice cubes: I used regular water ice cubes, however, it’s so fun to get creative here! Try making coffee ice cubes or oat milk ice cubes by freezing coffee or oat milk in an ice cube tray. This stops the iced latte from becoming diluted and watery as it does with regular ice.
✨ Optional ingredients
- Sweetener: If you like a sweet taste in your coffee, add your favorite sweetener. I love maple syrup or honey in this to make an iced honey oat milk latte, or for a low-carb version, I will use either keto simple syrup or brown sugar erythritol. If you’re adding a granulated sugar or sweetener, mix it well with the hot coffee before pouring it over ice so that it dissolves.
- Vanilla: Vanilla extract adds warmth and a depth of flavor. It is amazing with oat milk!
- Spice: A great way to add more flavor is with spices! My favorites are a pinch of cinnamon or pumpkin spice for a pumpkin spice latte.
- Coffee syrups: The sky is the limit here! Caramel syrup, chocolate syrup, vanilla syrup, Honey Strawberry Syrup, and sugar-free strawberry syrup are a few of my favorites.
- Flavor extracts: Extracts (other than vanilla) can add a boost of flavor with fewer calories than syrup. I always have salted caramel and hazelnut in my cupboard for coffee and other desserts.
🥣 How to make a perfect iced oat milk latte (step-by-step guide)
1. Make coffee: Begin by making strong coffee or espresso. I made my French Press Espresso which is the best way to make espresso without a machine.
2. Optional: add sweetener: If you want to add sweetener, now is the time to do it. I mix the coffee with syrup, sweetener, or sugar before the next step.
3. Add ice and coffee: Next, fill a tall glass with ice cubes and pour one shot, a double espresso shot, or coffee over the ice.
4. Froth the milk: this step is optional, but it makes a silky, creamy texture which really elevates the drink. I used a handheld milk frother that I found on amazon for around £10.
5. Pour the milk over the iced coffee.
6. If you frothed the oat milk and the cold foam gets stuck, scoop it out with a spoon.
7. Stir with a straw or a long spoon and enjoy!
🫙 Storage Instructions
Store this refreshing drink in an airtight container like a mason jar in the fridge for up to 3 days. If you added plain ice, remove it before storing it so it doesn’t become watery.
🪄 Recipe Notes & Tips
- Gluten-free: Not all oat milk brands are certified gluten-free. Check the label if in doubt!
- Hot oat milk latte: Make it hot by skipping the ice and heating up cold oat milk on the stove over medium heat or in the microwave. Don’t let the milk boil. You can then froth it with a handheld frother to get that delicious foamy topping. Oat milk is great for latte art. It’s almost like using whole milk.
- Other non-dairy milk: This recipe works with most plant-based milk. My favorite non-dairy options are unsweetened almond milk, vanilla soy milk, coconut milk, hemp milk, and macadamia milk.
🌈 More flavor options to make your iced latte taste amazing
For each of these flavors, mix the additional ingredients with the coffee before pouring it over the ice. You can swap out the sweeteners as desired, other than for honey or strawberry.
- Mocha: To make a mocha, mix 1 teaspoon of cocoa powder with the coffee. Be sure to add 1-2 teaspoons of your preferred sweetener as well, as the cocoa powder is quite bitter. If it becomes quite thick, mix it with a little oat milk before pouring it over ice.
- Chocolate orange: Mix 1 teaspoon of cocoa powder and 1/4 teaspoon of orange extract with the coffee, plus 2 teaspoons of honey. If it becomes quite thick, mix it with a little oat milk before pouring it over ice.
- Cinnamon dulce: Add 1/4 teaspoon of cinnamon powder and 2 teaspoons of maple syrup to the coffee.
- Skinny vanilla: Mix 1/4 teaspoon of vanilla extract with 1 tablespoon of keto simple syrup.
- Honey: Add up to 1 tbsp of honey. (My favorite way to make this!)
- Strawberry: Follow my Iced Strawberry Latte recipe and use oat milk.
