Grab A Glass—How to Make Homemade Oat Milk

If it suddenly seems like oat milk is everywhere you look, you’re not alone in this observation—oat milk is one of the most popular beverages on store shelves these days. And that’s saying a lot, considering the truly epic rise of plant-based milk options within the last several years.

But oat milk’s stand-out popularity is actually pretty understandable: it’s a seriously delicious way to do dairy-free. And even better, you don’t even need to buy it to enjoy its unique creamy benefits: Oat milk happens to be an exceptionally easy “milk” to whip up in your own kitchen.

What’s more, there are so many advantages to making fresh oat milk at home. For starters, it’s less expensive, and it allows you to use better ingredients, too. The DIY route even enables you to put a personal spin on the drink if you want, such as making your batch sweeter, totally unsweetened, chocolate-flavored … you name it!

But in the meantime, our recipe for basic oat milk is pretty fantastic all on its own. It uses extra clean ingredients (as in, have you ever looked at the ingredients of store-bought varieties? Some funky stuff is going on in there for sure!). Plus our recipe includes the tricks to making sure your homemade oat milk has the best taste and texture, as this type of milk is a little more than just throwing some oats in with some water. So don’t wait on this staple recipe: Give this awesome plant-based milk alternative a whirl.

Here are the tricks to whipping up your very own best-ever oat milk.

  • Don’t add too many oats. A common mistake amongst oat milk newbies is unintentionally turning their oat milk into more of an oatmeal by adding too many oats. That’s because dry rolled oats swell up dramatically with time, despite how watery they might appear when first blended with water. It may not seem like much oats go into our recipe, but trust us: It’s more than enough!

  • Fat boosts taste and texture. Since oats have a negligible amount of fat, a little bit of oil is needed to boost the creaminess of the milk. Learn more about the oil we use in our cooking video.

  • Sweeten as desired. Our recipe mimics an “unsweetened” oat milk—it includes a little sweetener (sugar-free monkfruit) for flavor, but has a more neutral flavor profile. If you normally choose sweetened plant-based milk varieties, add an extra tablespoon (or more) of monkfruit or your sweetener of choice to taste.

  • A soak is key. As oats sit in their blended water, they will separate, releasing a flavorful oat-y “milk,” and leaving behind a starchy sediment that you can think of like whey. This sediment is not enjoyable to drink and should be discarded, but it takes a full 24 hours to obtain the best separation.

  • The deal on separation. Once you’re ready to separate the milk from its “whey” sediment, give it a slight swirl, but don’t shake the container else the slimy sediment will combine again with the milk. Even in the finished milk, a little separation is normal (as this natural recipe does not use any gums or other emulsifiers), but the final mixture may be shaken prior to serving.

  • Adjust flavor as desired. Ready to get creative? Add a personal spin on this oat milk by adding flavorings like cinnamon, vanilla, chai, or cacao. There’s all kinds of ways to make your oat milk extra special!

Prep Time: 5 mins | Refrigeration Time: 24 hrs | Total Time: 24 hrs (mostly inactive)
Servings: 4
Author: Julie Morris 



4 cups water

1/4 cup rolled oats

1 tablespoon MCT oil, or other healthy neutral-tasting oil (like algae oil)

1 tablepoon monkfruit (or other sweetener), plus more as needed to taste

1/8 teaspoon sea salt



1. In a blender, combine the water, oats, MCT oil, monkfruit sweetener, and salt. Blend into a smooth, white mixture.

2. Pour the milk through a fine mesh sieve, into a sealable jar. Cover, and refrigerate the milk for 24 hours.

3. Give the jar a light swirl, and transfer the milk to another jar or pitcher, taking care not to transfer any of the thick sediment on the bottom.

Keep the milk refrigerated, and enjoy the finished milk within 7 days. A little separation is normal—shake prior to use for the richest texture.
