Earlier this year we made the switch from cow’s milk to a plant based milk, and oat milk is our favourite dairy alternative. I have wanted to make my own oat milk for months – during the first lockdown! I finally started to make it a few weeks ago and I can’t believe how easy and cheap it is! Here is how to make oat milk.

Directions for making oat milk

You can make this oat milk without soaking your oats, however I found that when I don’t soak the oats the milk tastes a lot weaker. I like to strain my oats for at least 2 hours, but I sometimes leave them overnight.

You will need 1 part oats to 4 parts water. You can measure that however you want. Here I did 1 cup of oats into each bottle, and then 4 cups of water. It doesn’t quite look like that due to the oats expanding though.

The following morning I just used the Ninja to blend up the mixture. I did this for about a minute for each bottle.

This is where I get very high-tech and stick some straining cloth to my jug using cellotape. Just make sure it stays on, whether that is with an elastic band, tape or magic.

Then strain your mixture. This can take ages if you don’t poke it with a spoon.

Then pour the strained mixture into your bottle or bottles, and bam, you have oat milk!

Storing your homemade oat milk

Store your oat milk in the fridge, and it will last for up to 5-6 days.

You will know when it is off because it will smell!

Will this oat milk separate?


Most milk alternatives do separate, but al you need to do is shake it up afterwards. 

Is oat milk vegan?

You would think that oat milk would be vegan, but just watch out for the oats you buy. Some are fortified with vitamin B12.

Does this work in tea and coffee?

It does!
