Everything You Need to Know About Oat Milk
On the lookout for a great oat milk recipe and find out everything you need to know about this dairy alternative that’s made a huge splash in the coffee world? You’ve come to the right place!

I have never been a big fan of milk. When I was a kid and my mom poured me a glass of milk at dinner, I remember sipping it slowly to avoid having to drink the whole glass. When I had a choice I opted for water. As I grew older I became a vegetarian at fifteen, and then a vegan in my thirties.
Almond milk has been my go-to milk alternative using it mostly in smoothies. When it comes to a dairy free milk alternatives in my hot drinks almond milk doesn’t cut it! It’s not creamy or sweet enough to make a delicious latte, which is one of my most favorite treats!

When I came upon oat milk, I was sold! Creamy, naturally sweet, frothy, it’s delicious. Not to mention it is easy and simple to make in less than five minutes. I’ve never attempted to make almond milk, and instead have gone for the store bought brands which have their drawbacks with additives, preservatives, and emulsifiers. When I discovered oat milk was simple to make at home, without the drawbacks of store bought dairy alternatives, I was ready to give this dairy alternative a chance.
In this post I’ll share everything you need to know about oat milk including:
- Oat Milk Ingredients
- Oat Milk Nutrition Facts
- Dietary Compatibility
- Health Benefits
- Drawbacks
- Comparison to Other Milks
What is oat milk?
Oat milk is a dairy free alternative to milk. It has gained popularity over the last year and can be found in coffee shops around the country. People love oat milk for its creamy and rich consistency, and mildly natural sweet flavor.
Is oat milk tasty?
Yes, homemade oat milk is tasty and delicious. When it comes to store bought oat milk tastiness varies on brand. See below for my recommendations of the best store bought oat milk, and my number one recommended brand.
What are the ingredients in homemade oat milk?
If you’re making your own oat milk there are only two main ingredients, water, and oats. You can choose to add a bit of vanilla extract are medjool dates to give it a bit more natural sweetness. You can add other natural sweeteners, or cocoa powder to make a chocolate oat milk.
What ingredients are in store bought oat milk?
If you’re purchasing store bought oat milk you can expect to get added preservatives, additives, emulsifiers, thickeners, and sugar. Some of those ingredients include: rapeseed oil, dipotassium phosphate, calcium carbonate, tricalcium phosphate, sea salt, dicalcium phosphate, riboflavin, vitamin A, vitamin D2, vitamin B12, and sugar.
What is the best store bought oat milk brands?
The best store bought oat milk depends on a few factors, taste, ingredients, and for many how it froths and tastes in their coffee. One of the big reasons people rave about oat milk is that it froths so well for lattes and other milky coffee drinks. I have to admit I love a good latte! But I also want natural ingredients. The drawback of many of the “barista” brands of oat milk is that they contain dipotassium phosphate which aids in the ability to heat and froth the oat milk. While it tastes good, it’s not the most natural ingredient. Here’s my take on the top brands, taste, ingredients, and ability to blend well in your favorite coffee drinks.
Califia Farms Oat Barista Blend

This brand is gluten free. If you have a gluten intolerance, you have to be careful when it comes to oats. While oats are naturally gluten free, they are often made in facilities that also produce products with gluten and could be cross contaminated. This oat milk is a barista blend because it contains dipotassium phosphate which helps it create a smooth and creamy froth for coffee drinks.
Oatly Oat Milk-Barista Edition

Oatly Oat Milk is not labeled gluten free. Their barista edition is creamy and froths well for coffees due to the added dipotassium phosphate. Oatly Oat Milk also comes in other flavors including Oat Milk Chilled, Low-Fat Oat Milk Chilled, and Chocolate Oat Milk Chilled.
Pacific Food Organic Oat Beverage

Pacific Foods makes an oat milk in original and vanilla. Some like the flavor in coffee because they find that it’s not overwhelming, while others don’t like the color.

Silk has their own take on oat milk in three flavors, Original, Vanilla, and Chocolate. Silk contains more additives than Califia and Oatly. Those who taste tested the Silk brand didn’t love it or hate it. Their biggest complaint about it was that it was creamy and had an aftertaste. The vanilla oat milk is extremely sweet, and not popular with taste testers. While the chocolate edition tastes like chocolate health shake.

Elmhurst Unsweetened Oat Milk is made with only three ingredients, oats, water, and salt. If you’re looking for the most natural store bought oat milk around this is the one. Elmhurst is also gluten free, While this oat milk doesn’t contain any gums or emulsifiers it was also ranked poorly for taste and separates in coffee.
My #1 Recommended Store Bought Oat Milk Brand
With all of the above considerations my number one recommended store bought oat milk brands is…
Califia Farms Barista Blend Oat Milk

This oat milk tastes great! It’s dairy free, nut free, gluten free, sugar free, carrageenan free, contains no gums or stabilizers, non-GMO, vegan and kosher. It also tastes great in coffee and on it’s own. It does contain the minerals dipotassium phosphate, calcium carbonate, and tricalcium phosphate, however these minerals are less worrisome than the gums and stabilizers of other brands.

Can I drink oat milk on my diet?
Oat milk is suitable for vegetarians, vegans, plant-based diets and those on a gluten free diet if you purchase or make your own oat milk using certified gluten free oats. If you are Keto, or Paleo oat milk is not compatible as oats are a grain and contain carbs. Oat milk does not contain dairy, eggs, soy, or nuts. It is a great alternative to nut milks for those with nut allergies. Be careful to read the label of the oat milk to be sure it was not made in a facility that also makes products with peanuts or tree nuts if you have an allergy.
What are the benefits of oat milk?
Oat milk has numerous health benefits. The health benefits listed are for store bought oat milk that have added vitamins. I recommend making your own oat milk at home to reduce your intake of processed added ingredients and have more control on the added sugar your oat milk contains. However, there are some health benefits to the added vitamins of oat milk.
Helps Prevent Anemia
If you’re a vegan or vegetarian you could be at risk for anemia if you’re not getting enough B12 or iron in your diet. These micronutrients are not found in most plant foods. Oat milk contains iron which can help reduce risk of anemia for vegetarians and vegans.
Strengthens Bones
Store bought oat milk often has added vitamin D and calcium. These micronutrients are essential for bone health. While calcium helps with bone maintenance and vitamin D helps with absorption of calcium.
Boosts Immunity
As mentioned above store bought oat milk is enriched with vitamin D, it’s also often enriched with vitamin A, two micronutrients that help with immunity.
Lowers Cholesterol
Oats are high in fiber and oat milk contains more fiber than other dairy alternatives. While eating a bowl of oatmeal will contain more fiber than oat milk, the added fiber in oat milk into your diet can help with lowering your cholesterol. Oats contain a soluble fiber called beta-glucan.
What are the drawbacks of oat milk?
While commercial brands of oat milk add vitamins that have health benefits to their beverage, there are also some drawbacks to drinking the store bought brands.
Additives, Preservatives, Sugar, and More
With the added vitamins also often come preservatives and sugar. We all know we don’t need any added sugar in our diets, and that preservatives in our food have an effect on our health. In order to make oat milk creamy, thick, and froth well in your coffee oat milk brands often add thickeners, and emulsifiers which can impact your digestive health and microbiome. Unless a brand is specifically labeled gluten free, you have to watch out if you have a gluten sensitivity. Many brands are also not labeled as Non-GMO or organic. That’s why my top pick
How does oat milk compare to regular milk and other dairy free milk alternatives such as almond milk?
Taste
Oat milk is naturally sweet like almond milk and thin like skim milk.
Nutrition
It’s higher in calories than almond milk and skim milk. Unsweetened almond milk typically has 30 calories per one cup. Skim milk typically has 98 calories per one mike. Oat milk has 110 calories per one cup. Oat milk is also higher in carbohydrates. It also contains more protein and fiber than almond milk, while skim milk contains more protein, oat milk contains more fiber as skim milk has zero fiber. For those on a low saturated fat diet who are also looking to lower cholesterol oat milk is a great alternative to regular milk.
How can you use oat milk?

Coffee/Lattes
Oat milk has made a big splash in local coffee shops. Starbucks has not yet gotten around to introducing this milk substitute as an option, but many small coffee shops do offer oat milk. It is enjoyed by coffee lovers because it froths well and has a creamy sweet taste that makes for an excellent latte or other milky coffee drinks. Try these 5 Homemade Oat Milk Lattes!
Smoothies
Almond milk is popular for smoothies. It adds some creamy and sweetness to those powdered protein shakes you can purchase. Oat milk makes a great add in for smoothies with it’s creamy sweet nature. It also adds a bit more protein and fiber to your favorite shake or smoothie recipe.
Soups
Use oat milk as a base for vegan creamy soups. I often use coconut milk for a cream base in soups, oat milk has less fat and calories than coconut milk, and is a nice substitue if you’re looking to cut back in calories in your favorite cream based vegan soup.
Cereal
Pour oat milk over your favorite cold or hot cereal or granola.
Pancakes Waffles
Use oat milk as a substitute for milk to make it vegan in pancake and waffle mixes. If you’re making vegan pancakes and waffles also check for eggs substitutes as necessary.
Baking
Need milk for a baking recipe, try oat milk instead. When making substitutions in baking it can be a bit trickier than other meals, as there’s quite a science to way the ingredients work together. Look for recipes that call for oat milk, before you start subbing oat milk in for milk in your personal favorite recipes. The recipe might not turn out as expected.

Are you ready to give oat milk a try?
There is a lot of information out there about oat milk. Various brands have come on the scene with their own version of this creamy, sweet, frothy dairy substitute. When choosing a store bought oat milk, look at the label. What’s in it? Be sure to buy an oat milk that is labeled gluten free if you have a gluten intolerance. Also, check to see how much added sugar is in your oat milk. With all the added sugar this healthy milk substitute isn’t so healthy anymore. You also want to stay away from emulsifiers and stabilizers. Making your own oat milk at home is easy, quick, and inexpensive. That’s what turned me onto oat milk in the first place.
This recipe is delicious, however I usually just use the oats and water. I used to make almond milk and got tired of all the soaking and cleaning. Making oat milk is so easy and quick, you can make it every day with very little effort.
Thank you for this awesome-looking easy recipe. I am curious how the foam of your homemade milk compares to the brands you recommend with the added dipotassium phosphate? I have tried the Barista + Oatly brands and both are not as foamy/creamy as regular milk (to be expected). So, I am curious if the homemade milk from your recipe is even less creamy? If yes, have you found any tricks to up the creamy foam texture? Thanks!
Yes, homemade versions are less creamy because they lack all added thickening agents and are made with simple ingredients. This recipe is just made with oats and water. If you want a creamy milk that is warm and foamy for lattes I suggest adding a tsp of coconut oil and using a milk frother to gently warm and foam the milk.
Still trying to make sense of the nutrition re: carbs. One brand claims people tell them their unsweetened is sweet, the label says it contains oats, water, salt and a gum, but also has 17gr added sugars which they say is derived from the processing, another says same ingredients,but only 3 gr total sugar.
If I am making my own – 1 cup oats, 1 1/2 cup macadamias to 4 cups water, no added sugars, fully strained, what is the carb count?
Hi Emma, I agree, food labels are difficult to understand. That is quite strange that one brand lists the sugars at 17 grams, while another lists it at 3 grams. I would not recommend using an oat milk with 17 grams of added sugar per serving. As far as the amount of carbs in the recipe you mentioned above, I’m really not sure. I sometimes use the recipe nutrition calculator from Very Well Fit to try to figure out nutrition information for recipes, but it won’t take into consideration that the milk is fully strained.
The nutrition facts, are those the numbers for the recipe with or without the dates?
The nutrition facts include the dates.
Hi Alison,
I’ve been looking to sub Califia barista blend, which I also found to be the best. However, it isn’t organic and apparently oats are sprayed with a Roundup-like chemical. Out of 61 food samples tested, 48 had some glyphosate in them. The most heavily contaminated were made with conventionally grown — as opposed to organically grown — oats. You can read the full results here: https://www.ewg.org/childrenshealth/glyphosateincereal/#.W3XNdnwnYd4. I found a recipe using oats, cashews and coconut flakes that I’ll try also. Thanks for your site!
Hi Maggie,
Thank you for the information about the Califia Barista blend. This is great information! I will keep note of it, and continue doing some research into the best store bought oat milks that are free of pesticides.
Easy and delicious
How long does the oat milk last? Not really worried, between my wife’s coffee, my iced coffee and cereal, I’m sure we’ll go through 3 cups fast
I recommend 3 days.
Hi Alison,
thank you for your recipes and suggestions. I’ve got one question, though, about the home made oat milk – in fact, when I warm it up for my coffee, it just turns into a very thick mass, not fluid at all anymore, thus unusable for latte. Is it something, I’m doing wrong? Before warming it up, it really is nicely fluid. I’ve read somewhere else, that that’s just what happens with home made oat milk and it could be fixed by adding oil to it, but I’m still hesitating to try.
Do you have any idea or suggestion?
Thank you in advance!
Hello Dusan!
Thank you for your response! I hear you with regard to the oat milk thickening when you heat it. Unfortunately, It’s unavoidable as oatmeal thickens when warmed too. In order to prevent it from thickening you do need to add oil. I suggest 1 tsp of coconut oil. This will help prevent it from clumping. I also suggest using a milk frother to gently heat the milk.
I am a dairy freak, love it, but I love to try different kinds of milk too. Have you tried hemp milk? I have made almond milk, same concept with water but takes a bit more time. I will totally try this.
I almost bought oat milk today at the grocery store but I wanted to know before I bought it so I thoroughly enjoyed reading your post. I’m excited to make my own and try the recommended brand too.
Wow, I had no idea about Oat milk until reading this informative post. I actually would love to taste it at this point. Thank you for all the info.
I’ve been getting tired of almond milk. Ready to try this as an alternative.
I will definitely try making my own Oat milk. I actually love oat milk and so excited to give this recipe a try!
I’ve never tried oat milk, but am definitely looking for other alternatives to dairy. I will be giving this a try for sure! Thank you! 🙂
I’ve never had oat milk. I am excited to try this out! Thank you for all of the great information!
Thanks, Kat! I hope you enjoy the recipe!
Recently fell in love w/ oat milk and haven’t yet tried making it, but I love the simplicity of this recipe—very similar to making nut milk! (And I hear it beats other milk alternatives for foaming in coffee!) Any up or down side to soaking oats ahead of time?
Hi Liza! There’s no need to soak the oat ahead of time. However, if you have the extra time you could soak them for 30 minutes. This would help them blend better when combining them with the water in the blender. If you go this route, you would want to drain the oats, discard the soaking water, and use fresh filtered water when blending.
