Want to make creamy oat milk at home with just 2 ingredients, 1 blender, and in 5 minutes! Let us show you how!
What is Oat Milk?
Oat milk is simply rolled oats and water blended together then strained to leave the pulp behind. The result is easy, creamy, DIY oat milk!
How to Make Oat Milk
To make oat milk simply add 1 cup rolled oats + 4 cups water to a high-speed blender and blend on high for 30-45 seconds. Then strain through a clean t-shirt or towel for best results.
We found nut milk bags let too much pulp through. Fine mesh strainers also let too much pulp through, so we don’t recommend using them.
This method yields creamy oat milk every time that’s perfect for adding to coffee, matcha, cereal, oats, baked goods, granola, and more!
How to make Flavored Oat Milk
You can also optionally add sea salt, a date, vanilla extract, cacao powder, or berries when blending for added flavor!
Oat Milk FAQs
How do you make oat milk not slimy?
- Over-blending can make the oat milk slimy in texture, which is why we recommend blending for about 30-45 seconds.
- Soaking your oats can also make the oats more prone to sliminess. Just add to the blender with water and blend!
- Sometimes heating your oat milk can make it become slimy, so we don’t recommend it. Good news: We have an oat milk recipe coming soon that’s inspired by Oatly Barista milk and is perfect for heating / frothing!
- We recommend straining twice to remove any of that excess starch which can also lend to a slimy texture.
- We recommend straining with a towel or clean t-shirt as nut milk bags and fine mesh strainers let too much pulp through.
Can you use steel cut or quick oats to make oat milk?
In our experience, rolled oats are the way to go. Steel cut oats are too unprocessed and make less creamy milk. Rolled oats are just right and make nice and creamy oat milk. And quick cooking oats are too finely processed and tend to create slimier oat milk.
Is oat milk gluten-free?
This can be controversial as some consider even gluten-free oats to be problematic for those with gluten sensitivity and celiac disease. But in our experience, certified gluten-free oats make oat milk gluten-free
How long does oat milk last?
Well sealed in the refrigerator, oat milk should last about 5 days. You’ll know it’s gone bad when it smells funny.
Why did my oat milk separate?
Separation is totally normal with oat milk and many other dairy-free milks. Simply shake well before use!

How to Make Oat Milk
- 1 cup rolled oats (gluten-free if GF // or sub steel-cut oats*)
- 3-4 cups water (use less water for thicker, creamier milk!)
- 1 pinch salt
- 1 whole date, pitted (optional // for sweetness // or 1 Tbsp (15 ml) maple syrup)
- 1/2 tsp vanilla extract (optional)
- 2 Tbsp cocoa or cacao powder for “chocolate milk” (optional)
- 1/4 cup fresh berries for “berry milk” (optional)
- Add oats, water (the lesser range will yield thicker, creamier milk, the higher range will yield thinner milk), salt, and any additional add-ins (optional) to a high-speed blender. Top with lid and cover with a towel to ensure it doesn't splash. Blend for about 30 seconds – 1 minute or until the mixture seems well combined. It doesn't have to be 100% pulverized. In fact, over-blending can make the oat milk slimy in texture.
- Scoop out a small sample with a spoon to test flavor/sweetness. If it’s not sweet enough, add more dates.
- Pour the mixture over a large mixing bowl or pitcher covered with a very thin towel or a clean T-shirt. In my experience, it benefits from a double strain through a very fine towel to remove any oat remnants. A nut milk bag seemed to let too much residue through.
- Transfer to a sealed container and refrigerate. Will keep in the refrigerator up to 5 days (sometimes more). Shake well and enjoy cold. DO NOT HEAT or it will thicken and become gelatinous in texture. It's delicious as is or added to granolas, smoothies, and baked goods!
*Nutrition information is a rough estimate calculated with no additional add-ins, and the oat “pulp” nutritional content removed.
