How to Make Homemade Oat Milk [Nut Free]

For anyone looking for a nut free plant milk option, homemade oat milk is for you. We use a lot of almond and cashew milk in our house, but I finally decided to expand our horizons and try something new. Oat milk is really simple to make, like most plant milks, and it’s a great way to ensure there are no added preservatives or fillers when compared to store bought options.

How to make homemade oat milk?

Well, it’s simple really. Only two ingredients required, plus an optional third. First soak your oats for about 30 minutes before draining and adding them to a high speed blender. Then add your fresh water and maple syrup if using, and process until smooth. Do not over process! Very important not to over process your milk, as it tends to get “slimy” if you blend for too long. So only until smooth.

Once smooth, you’ll need to strain your milk at least twice through a fine metal strainer, or use a cheesecloth. Store your milk in a lidded pitcher or container for up to 5 days.

How to use homemade oat milk?

You can use your homemade oat milk in almost any way you’d use any other milk. However, you don’t want to use oat milk to make hot chocolate or other beverages that would require the milk to be heated up excessively. This will change the texture of the oat milk, and also make it quite slimy. So any cold application works best, like in cereal or smoothies. I also enjoy this milk in my morning coffee!

    I love oat milk and can’t purchase it in stores where I live. Making it at home is easy and cost efficient. I do suggest running the milk through cheesecloth though, I find it a bit gritty without that step.
