What Makes This Recipe Different

While testing my oat milk recipe, I couldn't resist making a creamer version, too. Oat-based creamers are just so YUM. They're naturally sweet, creamy, and perfect in coffee or tea.

But when it comes to homemade, we have a problem to address-that pesky oat starch! It's why other oat milk recipes you've tried were nothing like store-bought.

Commercial oat milks and coffee creamers (like Oatly or Califia) get their sweetness and smooth texture from a process called enzymatic hydrolysis. But don't let the science-y bit scare you away!

I figured out an easy way to replicate it at home, and I'll walk you through it step by step. 👍

How to Make Oat Creamer That's Not Slimy

Alright, fellow coffee geeks-let's talk enzyme action.

First, an enzyme (amylase) helps thin out the oat-and-water mixture by breaking down starches, which makes it smoother and less gummy. Let's call this the "liquefy it" stage (liquefaction if you want to be proper).

Then in the second stage, those broken-down bits get converted into natural sugars. This step is called saccharification, and it's why your oat creamer tastes subtly sweet, even with zero added sugar. Ahhh, mystery solved, right?!

So yeah, it's science, but it's totally doable at home! ☕✨ You just need a digestive enzyme blend that contains amylase and glucoamylase. Plenty of vegan options are available online (I've linked two below).

Ingredients

rolled oats: According to this article, some oat beverage manufacturers use oat flour. Originally, I used whole rolled oats, and it worked great until only thick-cut rolled oats were available. Last year I noticed that the oats available at our local grocery stores, whether pre-packaged or from the bulk bins, were much thicker than the oats we used to buy. I realized they are TOO thick for the enzymes to work properly. So after more testing, I now recommend blending the oats into oat flour as step 1.
digestive enzymes: As mentioned above, to break down the starch and prevent our creamer from getting slimy in hot coffee, we're going to soak the oats with enzymes.
The most cost effective way to accomplish this is to use a digestive enzyme supplement that has both amylase and glucoamylase, like the two linked below. If you're shopping other brands, just make sure the product is vegan, has a similar amount of these two enzymes, and comes in capsules.

- NOW Supplements Gluten Digest
vanilla extract: For a flavor more similar to store-bought milks, I like to clear vanilla instead of pure vanilla extract, but either is fine.
fat: To make this oat creamer more like store-bought options (and dairy half-and-half) we need to add fat.
- For a nut-free option, go with a flavorless oil like avocado or grapeseed.
- For oil-free, raw cashews are the best option.
optional sunflower lecithin: If you decide to include oil, adding a teaspoon of lecithin helps with emulsification and keeps the oil and water from separating during storage. Did you know you can also use lecithin as a replacement for egg yolks in ice cream? Try it in this coconut ice cream recipe.

How to Make Oatmilk Creamer

Rolled oats blended into flour and put in large bowl.

First, blend the rolled oats for a few seconds on high speed until they are the texture of coarse flour. Pour into a large bowl, open one capsule of digestive enzymes, and dump the powder into the bowl.

Oats, enzymes, and hot water soaking in a large mixing bowl.

Heat the water to about 150 degrees. A thermometer is really helpful here, but not required. Pour over the oat flour and enzymes, and stir well. Let soak for 30 minutes. During this time the water will develop a sweet flavor as the enzymes do their work.

Pouring oat cream from a blender into a nut milk bag.

Rinse out the blender, and blend the oat/water mixture for another 10-15 seconds. You don't need to blend long since the oats were already broken down into flour. Use a nut milk bag to strain the oat milk directly into a large pot. I recommend placing one bag inside another for a double layer.

Using a thermometer to check the temperature of the oat creamer mixture.

Over medium heat and whisking occasionally, bring the oat creamer just to a simmer, about 190 degrees F. Remove from heat, and stir in the salt and vanilla.

Let cool for about 20 minutes, then return the creamer to the blender and add your choice of cashews or oil.

oil - while blending the oat creamer on high, remove the cap from the pour spout, and slowly drizzle in the oil. Stop and add the sunflower lecithin, and blend again to incorporate.
cashews - if you don't own a high-speed blender, getting the cashews completely smooth and creamy may be challenging.

Tip! Most oat milk recipes tell you not to squeeze the bag because they're trying to avoid making the milk/creamer slimy. But since the enzymes have already fixed this issue, it's fine to give it a squeeze.

Helpful Equipment

A few key items make preparing the recipe much easier. The great news is that once you have everything, you'll be able to make endless batches of creamer, reduce waste, and save money!

large mixing bowl - to soak the oats with the enzymes
blender - I use a Vitamix, but a standard blender is fine since the oats are very soft. It is a large volume, though, so you may want to blend it in two batches.
nut milk bag(s) - any type of fine mesh nut milk bag should be fine. I like to double-strain the milk by placing one bag inside another.
thermometer - this is helpful for measuring the temperature of the water for the initial soak and while simmering the creamer during the final step.
large saucepan - During recipe testing, I found that heating the creamer in this final step improves the mouthfeel and helps prevent separation during storage. It's possible it also helps deactivate the enzymes, though I'm not positive. I do suspect this step helps the creamer last longer in the fridge.

Flavor Variations

Do you have a favorite flavor of coffee creamer? Pretty much any flavor you can imagine, you can create with this oat milk base!

Add spices, extracts, and sweeteners, or simply use vegan-friendly syrups. Check out Mel's vegan coffee syrup recipes over at A Virtual Vegan for more ideas.

After preparing the basic oat creamer, I like to divide it among two or three small jars. I usually leave one plain and make one or two flavored creamers.

Here are a few flavors we've tried so far. Cinnamon roll is my favorite!

Per 1 cup (8 oz) of oat creamer, add:

cinnamon roll: ½ teaspoon ground cinnamon + 2 to 4 teaspoon sweetener
mocha mint: 2 teaspoon cocoa powder + ⅛ teaspoon peppermint extract + sweetener
toasted almond: scant ½ teaspoon almond extract + a few extra drops vanilla extract + sweetener
pumpkin spice: 1 teaspoon pumpkin spice + 1 tablespoon maple syrup or sweetener of choice

For a lightly sweet cup of coffee, start with 2 teaspoons of sugar per 8 ounces of creamer.

If you prefer a sweet coffee creamer, you might like as much as 2 Tablespoons of sugar/sweetener per 8 ounces of creamer.

One cool thing about making your own flavored coffee creamer is that you can choose the type of sweetener AND decide how much to use!

If you're anything like me, the sweetened non-dairy creamers at the store are often too sweet. So it's really nice to be able to balance the flavors to suit your own palate.

FAQ

How long does it keep?

Store homemade oatmilk creamer in a covered jar in the refrigerator for up to 6 days.

Can I use oat flour instead of rolled oats?

Yes, I've also tested the recipe with oat flour I purchased online (Anthony's brand), and it worked great! You may need to take a bit more care when straining, since commercial oat flour may be a finer grind that what you would create yourself in the blender.

Is it cheaper to make your own coffee creamer?

Yes! By my calculations, homemade oat milk creamer costs about 75% less than most specialty non-dairy coffee creamers.
Taking into account the cost of organic oats (approximately $0.70), one capsule of digestive enzymes ($0.17), water, vanilla, and oil, it costs a little over $1 to make this recipe. At 2.25 cups per batch, that's $0.11 per 4 Tbsp.
For comparison, Califia Farms Unsweetened Oat Creamer was around $5.80 for 25 fluid ounces the last time I checked. That comes out to $0.47 per 4 Tbsp.

Equipment

Ingredients

▢ 1¼ cups rolled oats - certified gluten-free, if needed
▢ 3 cups water
▢ 1 capsule vegan digestive enzyme - tap for example product; should contain amylase and glucoamylase
▢ pinch of sea salt
▢ ½ teaspoon vanilla extract - regular or clear imitation vanilla
▢ ½ cup raw cashews - or 2½ tablespoon flavorless oil
▢ 1 teaspoon sunflower lecithin, optional - an emulsifier

Instructions

Soak, blend & strain:

Put the rolled oats in a blender. Blend for about 5 seconds or until they're the consistency of coarse flour. Pour into a large bowl.
Open one digestive enzyme capsule and dump the powder into the bowl (discard the capsule).
Heat the water to approximately 150°F (66°C). I find it easiest to use a microwave. At this temp the water will feel very hot but won't immediately scald you.
Pour the hot water into the bowl with the oat flour and enzymes, and stir well. For reference, use a spoon to taste the oat water (it will be very bland). Set aside for 30-45 minutes. I like to stir occasionally during this time. After 30 minutes, taste the water again. It should now taste slightly sweet compared to the first taste. If it doesn't, either the enzymes aren't effective or the water wasn't the correct temperature. If you think the water was too cool, microwave the bowl for about 30 seconds to raise the temperature, and check again in 15 minutes.
Rinse out the blender to remove any oat flour remnants, and pour the oat-water mixture into the blender. Starting on low, quickly increase to high speed, and blend for about 10 seconds. You don't need to blend long since the oats were already broken down to flour.
Use a nut milk bag to strain the oat milk into a large saucepan. I like to place one nut milk bag inside another, for a double layer. Or you can strain it twice using the same bag (rinse it between uses). Since the starch has been broken down into sugars, it's fine to squeeze the bag. Note that if it feels slimy, this means the enzymes didn't work. Review the tips in the Notes section below before proceeding.
Save the oat pulp for baking or smoothies.

Simmer:

Over medium heat and whisking frequently, slowly bring the oatmilk creamer to a simmer. Aim for 195°F (90°C). If you don't have a thermometer, look for these visual clues: tiny bubbles around the edges and slight movement in the center, like it's just about to reach a full simmer. Whisking, maintain this low simmer for another 20 seconds, then remove from heat. Whisk in the salt and vanilla.

Add a fat for richness:

Let cool for about 20 minutes or until barely warm (for safety since hot liquids expand in the blender). Rinse out the blender jar, and return the creamer to the blender.
For the cashew option, add cashews to the blender, and blend on high until completely smooth. Don't worry about over-blending! It's better to blend too much than too little in this case.
For the oil option, while blending the creamer on high, remove the cap from the lid and slowly drizzle the oil through the spout.
Add the sunflower lecithin and blend for a few more seconds.
Pour into a clean jar and place in the refrigerator uncovered. Cover once cool. Keep refrigerated and use within 5 to 6 days.

Notes

Enzymes: Look for a digestive enzyme blend similar to this 365 product or this one by NOW Supplements. These are the only two I've tested. Based on my experience, you'll get the best results if it contains both amylase and glucoamylase.

Oat Creamer Flavors:

For a lightly sweet cup of coffee, start with 2 teaspoons of sugar per 8 ounces of creamer.
If you prefer a sweeter coffee creamer, you may want to use as much as 2 tablespoon sugar/sweetener per 8 ounces of creamer.

Per 1 cup (8oz) of homemade creamer, add:

cinnamon roll: ½ teaspoon ground cinnamon + 2 to 4 teaspoon sweetener
mocha mint: 2 teaspoon cocoa powder + ⅛ teaspoon peppermint extract + sweetener
toasted almond: scant ½ teaspoon almond extract + a few extra drops vanilla extract + sweetener
pumpkin spice: 1 teaspoon pumpkin spice + 1 tablespoon maple syrup or sweetener of choice

Tips & Troubleshooting:

RECIPE UPDATE: Since I first shared the recipe, I've heard from a few people who said their oat milk still thickened when heated. Initially, I thought the most likely issue was the type of enzymes used (which is still a possibility). But now I'm more convinced it's due to differences in rolled oats (thick cut). This is why I've changed the instructions to include blending the oats into flour. This solves the problem by giving the enzymes full access the starches.
When you first stir the hot water and oat flour together, taste the water for reference. After soaking for 30 minutes, the water should taste lightly sweet. The difference should be obvious. If it doesn't taste sweeter than before, either the enzymes aren't working properly or the water wasn't the correct temperature. If you think the water was too cool, microwave the bowl for 20 to 30 seconds to raise the temperature, and check again in 15 minutes.
That said, if you notice that the oat milk feels slimy while straining it, this means the enzymes did not work. There's no point in heating it in the next step, unless you want to turn it into oat "pudding." You can always salvage the batch by adding vanilla and a sweetener and enjoying it for dessert! Then review all of the steps to identify possible reasons why the enzymes didn't work.
