Iced Oat Milk Latte (No Store-Bought Milk)

Ever since I learned that you can make almond milk from almond butter and water, I’ve wondered what else we can blend to make creamy dairy-free drinks in just seconds. I feel like a mad scientist in my kitchen, seeing what I can toss into the blender next.

That’s how this iced oat milk latte recipe was born.

Instead of buying store-bought milk (which doesn’t always taste the best) you can blend rolled oats directly into your coffee. This means you won’t wind up with a diluted coffee flavor, and there are no added preservatives… but you still get to enjoy a creamy coffee drink!

This recipe is very easy to cutomize. I’ve included maple syrup, to help create a “shaken espresso” flavor similar to the one you’d get from Starbucks. But, you can create a pumpkin spice or chai flavor at home, too. Be sure to read the comments and recipe notes for tips!

Oat Milk Latte Ingredients

• Rolled Oats. I use regular rolled oats for this recipe, but quick oats should work, too. (Don’t use steel-cut oats.) If you need a gluten-free drink, make sure you buy certified gluten-free oats to avoid any cross-contamination.
• Maple Syrup. This natural sweetener helps the drink taste like a brown sugar shaken espresso from Starbucks, without having to worry about a granulated sugar dissolving.
• Black Coffee. All you need is regular black coffee for this recipe. No espresso machine required!
• Water. Since oat milk is made from oats + water, this is added to help dilute the coffee flavor, like regular milk would. If you prefer a stronger coffee flavor, you can use more coffee, instead.

How to Make an Oat Milk Latte at Home

Step 1:

Add the coffee, water, oats, and maple syrup to a high-speed blender. Secure the lid and blend until the mixture looks creamy, about 60 seconds.

Once the mixture looks smooth, taste it and adjust the flavor, if needed. You can add more coffee for a more bitter flavor, or a little extra sweetness, if desired.

Step 2:

Pour the blended mixture over ice and enjoy it right away. If your blender didn’t perfectly blend the oats, you can pour this through a fine mesh strainer on the way to your glass, so it will catch any sediment left behind.

Storage Tip: Oats tend to get slimier as they sit in liquid, so I don’t recommend making a big batch of this oat milk latte ahead of time. You can brew the coffee in advance, though! Then it will be ready to pour into the blender, and you’ll have a latte in 60 seconds or less.

Flavor Variations

• Iced Pumpkin Oatmilk Latte. For a pumpkin spice latte, try adding in 1 tablespoon of pumpkin puree and a 1/4 teaspoon of pumpkin pie spice to the blender with the rest of these latte ingredients. (You can make your own pumpkin pie spice blend at home, if you need to.)
• Iced Chai Latte. Replace the coffee with black tea or water. You might want to increase the pumpkin pie spice or sweetener slightly, so it tastes like the sweet and spicy chai latte from a coffee shop.
• Iced Mocha. Add a tablespoon of cacao powder and a little extra sweetener, to taste.
