Easy Three-Ingredient Oat Milk Recipe | How to Make Your Own Oat Milk at Home

Homemade oat milk is not only super easy, quick, and delicious, it’s also free from the preservatives and fillers you can find in most store-bought oat milk. With just three ingredients, a blender, and some cheesecloth, you can have your own homemade oat milk ready in minutes!

Homemade vs. Store-bought Oat Milk

I started making oat milk at home as an alternative to dairy milk because of my daughter’s eczema. Switching to plant-based milk was a successful move for us and cleared her eczema right up! However, not all oat milk are made equal. Many store-bought brands are filled with thickeners, fillers, artificial sweeteners, or preservatives that can be just as bad for you.

So I fell in love with making my own oat milk at home. It’s fresher, tastes better, and you can choose the quality of ingredients that go into it (I prefer organic rolled oats and organic honey!). All you have to do is try out this easy recipe to taste the difference. As a bonus, it’s much cheaper to make at home too.

Oat Milk in the Blender / Food Processor / Immersion Blender

The quickest and easiest way to make oat milk is in a blender. I like to use a high-speed blender to get this done in minutes but you can also do this with a food processor or immersion blender – though the blending time might vary.

When using the high-speed blender, I blend the oats for 50 seconds to 1 minute. For me, this is the ideal amount of time because any longer and your oat milk will come out with a slightly slimy texture. Ideally, you just want to blend until the mixture is opaque.

Best Way to Strain Oat Milk

I let the blended liquid sit for a minute or two so the larger sediments can float to the top. I remove them from the mixture before straining it through the cheesecloth and I find it just makes the process so much faster and easier.

Another trick I like to do is to turn the cheesecloth bag inside out. Oats tend to get stuck along the inner seam and make it a lot harder to clean when you’re done.

Also, make sure to be patient when squeezing the oat milk through the cloth. If you use too much pressure, some of the oats might break through the seams of the bag!

Why Soak Oats before Making Oat Milk

You might be wondering why I like to soak the oats overnight or at least for a few hours before making the oat milk. While you can also blend the oats immediately, I find that soaking them gives a much silkier texture to the finished product that makes it delightful to drink and add to other recipes. Though this step is somewhat optional, I highly recommend it!

How Long Does Homemade Oat Milk Last?

You can store your homemade oat milk in the refrigerator for up to 5 days. But in my experience, this recipe is so delicious that the oat milk is almost always gone before then.
