Pouring oat milk into a cup

Oat milk is trending. And when that happens, prices tend to go up. One box of it sells for $6 online. Not necessary. I’m showing you the super simple way to make it at home.

Oat milk is becoming popular for a good reason. It’s really creamy and works well in hot drinks. To make this creamy, dreamy plant milk, you just need cool water, a cup of oats and a good blender. I added a little maple syrup and vanilla for extra flavor.

Ingredients to make oat milk

  • Rolled Oats. Use traditional, old-fashioned oats not instant or steel cut.
  • Filtered water. I didn’t bother soaking the oats. I’m not convinced it’s necessary if you have a good blender.
  • Maple syrup, or something sweet. This part is optional but I like the hint of sweet from dates or maple syrup.

Oat Milk Ingredients

Blend the oats with cool, filtered water for 30 seconds – not much longer. Because of the natural fiber in the oats, if you blend longer, the milk will start to get a little goopy. I used the Vitamix on 5. Some blenders may need a little more or less time. So, blend for 30 seconds and add more time if your blender leaves large pieces of oats.

Once blended, you’ll be left with creamy, froth-worthy milk.

Best way to strain plant-based milk

Use a nut milk bag, cheesecloth, or fine sieve if that’s all you have. The sieve will take longer – and be messy if you are like me and try to hold it over a jar. You can, of course, use something more logical – like a bowl. If you’re going to make more of these kinds of non-dairy milk… invest in a nut milk bag. It’s reusable and you can pour a lot more through at once. I do have one but couldn’t find it!

Best ways to use oat milk

Once the milk is strained, add your flavors. In my case, it’s maple syrup and vanilla extract with a pinch of salt. Shake to distribute and refrigerate the oat milk for at least 3 days. Use it like you would any other milk in coffee, tea, or over oats or other cereal.

      It's the new old is new thing in non-dairy milk. It's creamier than any of the nut milks I've tried. And so easy to make! Reply

    How long will it last in the refrigerator? Your instructions said, "Shake to distribute and refrigerate the oat milk for at least 3 days." Do you have to wait 3 days to use it? Reply

      Hi Rita. It's ready to drink and use as soon as it comes out of the blender. But I've made it many times since this post and find that it will last 4-5 days easily. Enjoy! Reply
