How to make Oat Milk (that’s NOT slimy! Finally!)
How to make oat milk in under 3 minutes for a creamy and smooth dairy free milk! This oat milk is NOT slimy and is a perfect dairy free nut free milk option!
I won’t lie. I absolutely love buying oat milk. It’s my absolute favorite dairy free milk on the market, and word on the street is that it’s actually one of the most sustainable options for dairy free creamer options.
But sometimes, I’m in the middle of a recipe, and I run out, or I just don’t feel like spending the money.
What’s more, many non-organic oat milks can be filled with glyphosate (which is why using your own favorite glyphosate free oats ensures that your oat milk isn’t filled with this!).
Enter in the best method for how to make oat milk.
Seriously, I have some secret tips for how to make non-slimy oat milk. Because if you’ve ever tried to make this before, you’ve probably ended up like me and made some odd and bizarre gooey form that I imagine feels like eating that green slime on Nickelodeon.
So first, let’s go over what you’re doing that’s creating the slimy oat milk recipe, then I’ll walk you through how to make it non-slimy.
Oat milk is fabulous in smoothies, drinking as is, as a coffee “creamer,” and even wonderful in baking vegan cakes.
Is it cheaper to make or buy oat milk?
I’ve done the math for you: purchasing oat milk can range from $3 to even $7 per gallon. Making your own oat milk can cost as little as $0.70 for the same amount.
Of course, this is dependent upon which oats you’re using, and which brands you’d typically buy. But it can be much cheaper to make your own oat milk, if you’re interested in saving some money!
Why is my oat milk slimy?
So if you’re like me and have tried to make oat milk before to no avail, you’ve probably encountered: the slimy oat milk.
This happens for a few reasons that I’ve noticed others don’t really mention.
First off, many say to soak your oats. Do not do this. This activates the enzyme in oats that usually makes them bind together (like in overnight oats).
If you’re concerned about this enzyme (a few people are because it can sometimes irritate people’s digestive tracks), you can always purchase sprouted oats, like I do!
The second reason why your oats turn out slimy is because the water you’re using is not ice cold. Think about it. You cook your oats in warm water, right? If you’re using anything but cold water, you’ll start to activate the oats to form that slimy texture we all know as oatmeal!
And the third reason why your oat milk recipe is coming out slimy is that you’re squeezing the oat milk out of the nut bag. But I’ll go into how to actually strain the oat milk from the pulp in the next section!
Oat milk ingredients:
Making oat milk is truly my favorite of all dairy free milks to make because it literally takes all of 3 minutes, and doesn’t require any prep beforehand (who remembers to soak the nuts before you actually make the nut milk?! Not me ha!).
And what I love about this specific recipe is that it only uses mainly 2 ingredients, with 2 optional ingredients (though I highly recommend!):
- Rolled oats: You can actually even use sprouted rolled oats, such as One Degree Organics (what I used here). If you’re gluten-free, please ensure that you’re using gluten-free oats that are certified gluten-free.
- Optional: dates, vanilla extract, a pinch of salt, (or even maple syrup!)
How cool is that? Each of the optional add-ins add their own flavors to the oat milk. I do recommend adding in the date and the vanilla extract just for a touch of sweetness. Then it’s perfect in sweet baking recipes, or in coffee or smoothies. One single date does the trick, and just a teaspoon of vanilla. However, if you’ll be using this non slimy dairy free milk for savory recipes, then omit the date and vanilla and use the sea salt.🙂

How to make oat milk (that’s actually creamy, not slimy)
For the full written instructions and ingredient measurements, see the bottom of this post in the recipe card. You can also hit the “jump to recipe” button at the top of this post! Here, we’ll go over a brief overview of the steps, along with providing visuals for a better understanding of the recipe.
Now let’s go over how easy it is to make oat milk:
- Place all ingredients into a blender and blend for only 30-40 seconds.
- Place a cheesecloth, nut milk bag, or thin towel over a large bowl, and strain the oat milk into the bowl, catching the oat pulp in the cheesecloth or bag. If you don’t have any of these options, you can use a super fine-mesh sieve; just be sure to really double strain this oat milk!
- Remove the oat pulp.
- Once all of the liquid and the leftover oat pulp is into the cheesecloth and bowl, lift the cloth or bag up and gently let the remaining liquid drip into the bowl. You can lightly squeeze but don’t squeeze as you would nut milk, or you’ll get slimy oat milk.
- Discard or save the pulp for another recipe, and pour the oat milk back into the blender.
- Strain again.
- Cover the bowl again with your cheesecloth or nut milk bag, and repeat the process once more, catching any oat pulp in the cheesecloth.
And that’s it! Simply pour your double strained oat milk into a clean glass bottle or container and store in the fridge! Seriously this process takes all of 3 minutes and is great for when you’re in a pinch for something creamy to put in your coffee or a sweet recipe 😉
Tips for getting the perfect oat milk every time
I just want to make sure that when learning how to make oat milk, you get all of the best tips so that we can avoid any oobleck messes, like I created while figuring out the best methods for making oat milk!
- Make sure your water is ice cold. Again, we’re making oat milk, not oatmeal haha!
- Do NOT squeeze the oat milk through the cheesecloth or nut milk bag. Oats are not like nuts! They act a bit different, so when you’re squeezing the oat milk, you’re also squeezing through the phytic acid that creates the gooey slimytexture.
- Do NOT soak your oats. Again, this will yield in a slimy oat milk, which is not what we want!
- Double strain the oat milk to yield the creamiest and smoothest texture. Just a bit of extra work, but the whole process start to finish really does only take 3 minutes!
- Do NOT over blend!! Only blend for maximum 40 seconds, less is even better! Aim for 30-40 seconds, as any more will yield a slimytexture.
- Make sure to store your oat milk in a sealed container: I recommend a Weck or Mason jar that seals airtight. This will help keep your oat milk very fresh!
- If after a day, you notice some oat sediment on the bottom of your glass, don’t worry: This is natural, since we don’t have any gums or thickeners in this non-dairy milk. Simply shake the glass a few times to get your oat milk creamy again.
What can I use oat milk for?
So many things! Really, anything that you would use regular dairy milk or another dairy free milk for. Smoothies, creamy soups, vegan custards, coffee.. the list goes on! I love using oat milk in herbal coffee because I find it creamier without the coconut milk taste.
It’s also wonderful in baked goods, like this vegan vanilla cake, or raw desserts, like this easy chocolate cheesecake.
You can even just drink this oat milk straight up! It’s that good, especially if you’re adding in the date and vanilla.
How do I know when my oat milk is bad?
Usually, homemade oat milk lasts for about 5 days in the fridge. However, you’ll notice that it starts to smell a little funky when it goes bad if it’s left there too long.
Yes, this is shorter than store bought dairy-free milks, such as almond milk, but it’s also not filled with preservatives that make their shelf life last longer. And, if you’re like me, you go through oat milk pretty fast so no need to worry about your homemade oat milk going bad!
Can I make oat milk without a blender?
Yes, you definitely can still make homemade oat milk without a blender! If you have access to a food processor, then that’s all you need.
How do I make chocolate oat milk?
If you’d like to transform this classic oat milk into a chocolate oat milk, simply add in 2 tablespoons of melted vegan chocolate into the blender after you’ve blended and strained your oat milk. Pour your oat milk back into the blender and blend again until smooth!

This is so helpful!! Thank you!! Also love the casual oobleck reference hahaha
Aw that’s so awesome to hear, thank you so much!! Hope your oat milk making went well!
I normally make a hot latte as my morning cup. so 1/4 strong espresso and the rest milk. The theme seems to be heat -> slimy oat milk.Is there a way to do a hot latte with the homemade oat milk, without it turning slimy?
So far, I’ve reheated this and haven’t had a problem with it turning slimy, and some of the other readers have had the same success (comments on YouTube!) so it should work! Just make sure to double strain- that’s what really helps this oat milk stay not slimy, despite heat!
Favourite thing to do with the leftover oats? Maybe a face mask or something? 🤗
Oh I LOVE that idea!! I’m going to try that!!
I give the leftover oats to my teen for face masks and back masks to help with her acne, or I put them in lactation cookies for my breastfeeding daughter. Either way they definitely don’t go to waste!
Agreed on not letting them go to waste!! These are GREAT ideas!!
I make granola bars..cranberry, Choc. chips maple syrup chia flax cinnamon vanilla stir with strained oats Dehydrate or oven
LOVE this idea!! Going to try it myself!
hi! im going to try it soon. one question I have is: what do you do with the leftover pulp? any ideas?:)
Hi Jaye!! Yay! Can’t wait to hear what you think 🙂 Here’s a great list of ideas: https://sarahbassett.co/oat-pulp-ideas/ I’ve also just stirred some into oatmeal before I cook it and it works great!
hello!! i just made this and I’m obsessed. one thing though – mine tastes pretty watery and I assume that might just be normal. or is it possible to reduce the amount of water? thanks so much for your info!
Hi Ally! Aw I’m so glad to hear it!! Yes, I’m wondering if it was the type of oats you used- but you can totally reduce the amount of water, and it would be creamier! Enjoy!
My first try at oat milk was a slimy disaster, but I’ve just made a perfect batch thanks to your recipe tips!!
I have discovered the solution for slimy oat milk that requires no extra ingredients. Oat milk is slimy because there is starch in the oats. Starch is not soluble in water, it absorbs the water and makes the slimy texture. Starch is a chain of sugar molecules, but if you break those chains into smaller chains they are soluble in water. This is called dextrin. So if you can convert the starch into dextrin you will not have slimy oat milk. The way you do this is to bake the oats at 275 for 60 minutes. I first ground the oats to flour which makes smoother and creamer oat milk, and then bake them. The resulting milk has a tan color, as that is the color of dextrin, but it is not at all slimy.
You blend the baked oat flour with water afterwards? If so, for how long?
If it’s flour then I assume you can’t strain it?
You’ll be able to strain it through a cheesecloth because it’s not as fine as store bought flour 🙂
The first time I made oat milk, I followed instructions I saw on a youtube video that involved squeezing the bag. mistake. The results were definitely slimy. Following your instructions, i made perfect, non-slimy oat milk. Yay! Thank you so much for the tips as we love oat milk and making our own will save us a lot of money!
I’m so so happy to hear that you’ve had success with these tips 🙂 Yes, many people think making oat milk is like making a nut milk, where you have to squeeze the water out of the bag, but it’s the opposite!! Thank YOU so much for this review!! Definitely try using the homemade oat milk in one of these recipes, it truly makes it so special!! 🙂
Oobleck! Equal parts water and cornstarch, add some food coloring for extra fun! My boys and I love it. Haha
Also, I just got what seems like the same bracelet you’re wearing for Mother’s Day today! (Red Jasper?)
Lastly, THANK YOU for the best oat milk recipe ever!!! Never buying it again!!
SO HAPPY you loved it!! And yes!! It’s red jasper!! How awesome 🙂 Happy belated Mother’s Day to you, and enjoy!! Thanks for being here! 🙂
I’ve got a 5kg bag of ultra fine oats… Will these work the same??
Hi there! By ultra fine, do you mean they’ve already been processed into almost a flour? If so, then I would advise against this! The blender would end up not doing enough work, so your oat milk might end up gritty!
I’d like to try this soon. Can the oat milk be frozen into cubes to use later in shakes. Thank you
Yes, absolutely!! Genius idea 🙂
It sure is! So why on all the oat milk cartons i read does it say not to freeze it??
Do you have any recipes for the oats after making the oatmilk with them? Hate to just throw them out.
Hi Sarah! I don’t have an official post, but I typically just stir them into my oatmeal or add them to a smoothie 🙂 Here’s a great article, though, I’ve heard of a few people that use them for face masks, etc! https://sarahbassett.co/oat-pulp-ideas/
Thanks for sharing and I have managed to make my favourite oat milk with no more slimy.
Great simple way, I made the mistake of doubling my cheesecloth when straining first time, much better to strain twice. I like being able to make it so quickly and adjust the sweetness. It was very watery compared to the commercial products but smells and tastes much better.
How do people thicken oat milk in cheesy sauces? I was thinking of trying cornflour…
Exactly what I was looking for. I was sure it was less expensive than buying milk.
I’m also a vegan. Thanks!
So happy to hear it!! Enjoy 🙂
What can I use instead of cheesecloth?? I want to make this now for my daughter leaving for college tomorrow. We have been looking for a good reliable recipe.
Hi Elissa! Oh yes, you can also substitute in a thin cloth napkin or very thin dish towel if you have them. Just make sure that it’s clean! 🙂 Enjoy!
When you say “pour the oatmilk back into the blender…” is this just to use as a vessel to pour it back out to strain it again or am i supposed to blend it again before the second straining? Sorry, I wasn’t clear about that. I’m excited to try this recipe, so I didn’t want to mess it up :))) Thanks!!
Yes, exactly, you’ll just pour it back in as a vessel to then strain it once more! I just figured it was easiest that way 🙂 Less hassle! Enjoy!
works awesome! thanks!
That was an EXCELLENT question!!!
I noticed some recipes use a dash of sunflower oil. What is the reason for that?
I’m thinking that was probably to help make the oat milk creamier, but if you don’t squeeze too hard and you do the double strain, you’ll still get really creamy oat milk!
Easy Peasy Perfect. Thanks so much!
So glad you loved it!! Thanks for the review! Enjoy!
Can you make it using a French press coffee maker?
Hi Pam! I wouldn’t recommend that, as I would imagine it squeeze the oats too much, which will result in slimy oat milk. I hope that helps!
Hi! I can’t wait to try this recipe. Can I use quick 1-minute oats?
Hi Krysten! I would stick to rolled oats- you’ll get a creamier milk!
Thanks so much. loved all the information you provided. My first attempt turned out well. I will use chilled water next time. I had some difficulty steaming it for use in a latte. Do you have any recommendations to make the homemade oat milk better for steaming?
Hi Dennis! So glad to hear it! So I actually have a trick- to create foam, I pour the unheated oat milk into a blender and blitz it for 30 seconds- that will create the foam. Then you can pour the milk into a tea pot or saucepan, being mindful of the foam, and heat it that way. Or microwave, whichever is preferred!
Thank you for sharing.
can i heat this oat milk? its not gonna be slimmy ?
Hi Isabel! Correct, you can heat the oat milk, and it won’t be slimy! 🙂
I quarted the recipe to make enough for a single glass of oat milk. It turned out pretty decent! I didn’t have dates and I used a sieve and the texture wasn’t slimy at all. I think when I make this again I will cut down the amount of water down so it is less watery. I prefer a creamier oat milk.
It worked! Homemade oat milk with NO SLIME! Thank you for the money saving recipe and most of all the great tips.
Woo!! I’m so happy to hear it!! Enjoy 🙂
I can’t wait to try this and I am wondering how you would make pumpkin oat milk like the one they have at trader joes? Thanks
Omgsh that sounds so good, I’ve yet to try that! Hmm, without trying it and just looking at the ingredients, I would imagine that you would make the oat milk, then with the finished oat milk, you’ll blend it with pumpkin puree, pumpkin spice, a pinch of sea salt, and maple syrup (my preferred sweetener since it’s easier to mix into cold liquid!). My guess is that they probably heat the mixture together, which is why it’s easier to use cane sugar then, but you shouldn’t have to if you blend it all really nicely together!
I want to make oat milk ice cream. Do you think it being slimy would be a good /bad thing for this purpose?
Hi Melissa! You absolutely can use this as a base for ice cream! Here’s my recipe 🙂 https://thebananadiaries.com/vegan-vanilla-ice-cream-recipe/
I actually use oat milk in one of my soap recipes! I love it and this will probably be even better for me to use. thank you!!!
You said in the beginning strain first then back in the blender add vanilla dates and salt
Later you said all ingredients and strain
I don’t want to lose the thickness from the dates. Yes I like a few of them in there.so I add after straining and blend again. I like it frothy using only in coffee w cacao
nut bag. cracks me up 😆
Love this oatmilk! I did use half the quantity of vanilla (taste preference). It turned out really smooth and was so easy!
So so happy to hear this! Enjoy 🙂
Thanks Britt! This is a great tutorial on how to make oat milk! I love the fact that it only takes around 3 minutes and it’s not slimy like other oat milk recipes out there. The instructions are really clear and easy to follow, and the optional ingredients give you some flexibility when making the recipe. Thanks for sharing!
thanks alot of information keren banget
Love this recipe. Been making it for months. One question – do you rinse the blender and/or bowl between the first and second pour?
So happy to hear it!! And no I don’t I just do one big clean after I make the oat milk 🙂
Awesome thanks. Also wanted to share I take the oat pulp and mix it into a bowl with half a can of pumpkin purée, pour into molds and freeze for treats my dogs love. Takes like 2 minutes to just mix and pour.
**only do this if you’re making the recipe without vanilla**
LOVE this idea!!!
Great recipe and so much cheaper than store bought!!! I made mine with some almond extract and vanilla and then put in ice cube trays for my coffee!!! So Delish!!!
This is wonderful!! So happy to hear it 🙂 Enjoy!!
Hi! I couldn’t seem to find the ratios or measurements for oats and water to use for this recipe. Can you advise? Thank you!
