How to Make Oat Milk

Learn how to make oat milk at home! With this easy recipe, it always comes out smooth & creamy - perfect for adding to coffee, baking recipes & more!

Oat milk

Have you tried oat milk yet? Lately, it seems to be popping up everywhere. You can add it to your coffee at Starbucks, buy a carton of it at the store, or even pick up a pint of oat milk ice cream! I had to see what all the fuss was about, so I tried making my own homemade oat milk. I have to say, I’m hooked! It’s super easy to make, it’s smooth and creamy, and it has a yummy oat-y flavor that tastes great in coffee or tea.

Unlike other non-dairy milk recipes, this one doesn’t require any special equipment (looking at you, nut milk bags). And because you don’t need to soak the oats beforehand, it takes minutes to make. All you need is 5 minutes, a handful of whole rolled oats, filtered water, a fine mesh strainer, and a powerful blender! What are you waiting for?

How to Make Oat Milk

Making delicious oat milk is easy! But if you have made other plant-based milks in the past, a word to the wise: it is NOT like making almond milk, where you wring as much liquid as you can out of a nut milk bag. In this recipe, your goal is to squeeze and press the mixture as little as possible. Otherwise, it will end up slimy and grainy. Here’s my method:

  1. Blend. First, I add the oats and filtered water to a powerful blender (I use a Vitamix) and blend for 30 seconds, until the water looks creamy and white. For the best texture, be careful not to over-blend!
  2. Strain. Next, place a fine mesh strainer over a large bowl and pour the oat milk through it. Some liquid may pool at the bottom of the strainer. That’s ok! Discard this liquid and any oat pulp below it. DO NOT try to press the pulp to get more liquid through the strainer, as it will make the milk slimy and gritty.
  3. Strain again (optional). For extra-smooth oat milk, strain the liquid twice, discarding the leftover pulp both times. This step is optional, but it will yield the smoothest final texture.
  4. Chill, and enjoy! I like my oat milk best when it’s cold from the fridge. Unlike other dairy-free milks, don’t shake it when you go to use it. Instead, allow any leftover oat pulp to settle at the bottom of the container, and pour the creamy milk off the top.

How to Use Oat Milk

Once you’ve made oat milk, use it as you would dairy milk, cashew milk, or any other type of milk you like. I like to chill it and drink it with ice, add it to coffee, or use it to make a matcha latte. It would also be great in breakfast/brunch oat-y recipes like oatmeal, baked oatmeal, overnight oats, or no bake cookies. Alternatively, use it in any brunch baking recipe that calls for milk, like my vegan chocolate cake, blueberry muffins, banana bread, or cinnamon rolls.

Because it has a strong oat-y flavor, I don’t recommend using it in savory recipes. You’ll find my favorite way to enjoy it in the recipe below. I like to add a pinch of salt and a splash of vanilla and maple syrup to sweeten it up!

Next, try these plant based basics: tofu, tempeh, quinoa, chickpeas, or lentils.

There's no need to get store bought oat milk when you can make your own at home! Creamy and smooth, it's perfect for adding to coffee, baking recipes, or cereal!

Ingredients

  • 1/2 cup whole rolled oats
  • 3 cups water
  • 2 teaspoons maple syrup
  • ½ teaspoon vanilla extract
  • teaspoon sea salt

Instructions

  • Combine the oats, water, maple syrup, vanilla, and salt in a blender and blend for 30 seconds.
  • Place a fine mesh strainer over a large bowl and strain the milk without pushing any excess pulp through the strainer. This will create a creamier texture that’s not gritty or gummy.
  • Add more maple syrup, to taste, if desired. Chill overnight. If you want to drink your oat milk right away, I recommend adding ice - it's flavor is best when well chilled.

Notes

If you're gluten free, be sure to get oats that are Certified Gluten Free.
As the oat milk sits in the fridge, natural separation will occur. You can shake it, if you like, but I like it's texture best when I leave pulp at the bottom and pour off the top.

    How long does this typically stay good in your fridge?

    • Jeanine Donofrio

      about 5 to 7 days

    Would quick oats work for this?
    I don’t usually buy them but they were on sale and since i have to buy gf oats, i went for it. Thank you 😍

    • Jeanine Donofrio

      I haven’t tried, (I only keep whole rolled oats on hand) but I think it would be fine.

    Just a note for those without a blender, this worked well with an immersion blender stick. Might be a bit more oat bits left over after sieving but I’m using them in my morning oatmeal. Next time will plan on making oat muffins with the leftovers. I like oat milk and find it sweet enough without additional sugars.

    I’ve made oat milk a couple times and find that it is very different (in a bad way) from the store-bought kind. It pretty much tastes like lackluster oat-flavored water. I hope your recipe yields different results, because 1. I’d rather not keep buying it (and creating more packaging waste) and 2. I’ve recently learned how horrible almond mild is for the environment, so oats are the way!

    • Jeanine Donofrio

      Hi Jenna, homemade plant milks are never going to be exactly the same as store bought ones which often have fillers and stabilizers, but we really like this method and I hope you do too!

    That is some awesome photography! I too enjoy making milk at home. I often make Almond milk..but I need to try this Oat milk soon. Love that it’s so easy to make milk at home.

    sounds interesting as a non-dairy option, guess I’d missed the trend on oat milk so appreciate your sharing it here

    What are your thoughts on soaking the oats? I always soak oats to ease digestion but wondering if it would be different when making oat milk?

    • Jeanine Donofrio
      01.14.2020

      Hi Kim, it’s not a necessary step and I think it might make the texture more slimy. But I haven’t tried it, so I’m not sure.

    Any clever ideas out there on how to use, not toss the resulting oat pulp?
    Thanks!

    • Jeanine Donofrio
      01.14.2020

      There’s barely any oat pulp – I wouldn’t even really call it pulp, it’s maybe a tablespoon of foamy slime around the strainer. One of the nice things about oat milk vs. almond milk is that it all nearly gets incorporated.

    • Lisa

      I dry the pulp out in my oven, I then use my stick blender to make oat flour to make my dogs treats, works well with coconut n almond pulp to!

    • Sara Eberlin

      My grandma always shaped leftover oatmeal into patties and fried them on the stove like a pancake. I did that with my leftover pulp and it made a nice quick breakfast 🙂

  10. This is healthy for body and yummy taste.

    Hello! Do you think this would heat well in a milk frother?

    • Jeanine Donofrio

      Hi Charlotte, I don’t have a frother, so I’m not sure.

      I put it in my frother mostly so I can have it warm instead of cold when adding to my coffee. It doesn’t give you that latte foam but it heats up nicely and works just fine.

    Thank you Jeanine. Such a great recipe as not a big fan of buying packaged/cartons of oats or almond milk. Love the fact this milk is home made and non dairy, You know exactly what’s in it, is super easy peasy to make, low cost and without packaging. Am amazed just how quick and easy it was/ is to make. Took less than 3 mins! 2 mins washing up! Brilliant!

    Hi there, I followed the recipe exactly, including the 30 seconds, I have a ninja blender. And mine was pretty watery and had like a quarter cup of pulp. Do you think it needs more blending?

    • Jeanine Donofrio
      01.18.2020

      Hi Hope, if it’s not as thick as you like, you could blend a little longer and/or add more oats. Every blender will be a bit different.

    Really love this recipe! I have been making oat milk before and can tell you that if you get watery or slimy oat milk, you should follow a few recommendations:

    1. blend well for no more than 45-50 seconds
    2. strain twice for avoiding slimy oat milk and excess starch
    3. skip soaking the oats, just blend them and strain with fine cloth.

    Overall, what Jeanine recommends in the recipe is the way to go.

    For cold oat milk, fill last cup of water with ice and then fill with water. This will chill the oat milk.

    Fantastic – first try at making oat milk. Trying to get away from almond milk and this is absolutely delicious!

    Do you think that steel cut oats would be good for this? I have a bunch on hand and would be interested to try it.

  19. Kala

    Is the milk supposed to be like a weird off- white translucent watery substance when the pulp settles?

    • Jeanine Donofrio
      03.25.2020

      You can shake it before you use it, if you’d like.

    can you tell me what speed on vitamix you use? no one seems to say that but obv. low vs. high for :30 will differ greatly. I also think straining 3-4x is key. I’ve made about 5 batches so far, I’d also add that i like cinnamon and salt in it as well. my 2yr old loves it. thank you

    Roughly how much oat milk does this recipe make? I have never made this before. ☺

    • Jeanine Donofrio

      Hi Deb, about 3-ish cups

    Thanks for sharing! Does it keep long?

    • Jeanine Donofrio
      04.14.2020

      Hi Vanessa, I keep it about 5-7 days (since there are no preservatives in it compared to store-bought milks).

  25. Judy
    05.05.2020

    Do you discard the oat pulp or can it be used and eaten

    • Jeanine Donofrio
      05.05.2020

      I discard it, it’s pretty foamy (unlike almond milk pulp) and there’s not a lot of it. I suppose it could be dried and re-used but I haven’t tried yet.

  26. Meghan
    05.21.2020

    Any ideas on what could be done (if anything) with the left over pulp after straining? I’m all about reducing waste….will likely put it out with the compost but any cool ideas for further consumption? Thanks!

    Where did you get those beautiful glass milk bottles? <3

    Can you use the discarded oat pulp for anything (e.g. porridge)?

    • Jeanine Donofrio
      06.24.2020

      You could mix it into your porridge, that would be a great use. It wont be enough to make a whole bowl on it’s own.

    Hi!

    I’m new to oak milk and I’m interested in making mine own. Could I use honey instead of maple sugar?
    Also I love your first book (I borrowed it from the library and still have it do to the virus & the library is still closed- ☺️ Lucky me) and I look forward to ordering your newest one. I’m a new pescatarian trying to avoid carbs/sugars. Wish I changed my diet years ago (65lbs gone in 6 months) ☺️

    • Jeanine Donofrio
      06.24.2020

      Hi Sophie, yep, you can use honey! I’m so glad you’ve been enjoying the book 🙂

    Loved it! So yummy. I just moved and didn’t have a blender yet so used a food processor. It was messy but worked fine.
