How to Make Oat Milk

Plant milks have been a staple in our pantry. Almond, soy, cashew, coconut, oat milk – you can say that I have tried my fair share of plant-based milks. One of my favourites is definitely oat milk. Sweet, thick and creamy, I love it in cold brew but it is amazing all on its own. It is more neutral-tasting and requires less resources to make compared to nut milks.

This week, we will be making oat milk from scratch. The recipe is adapted from this one from Cookie and Kate. This requires only two simple ingredients and a blender (my 20 year old, hand-me-down Oster blender handled it beautifully). It is so easy to make and keeps amazingly well.

Here’s What You Need:
  • 1 cup of organic, large flake oats
  • 2 to 4 cups of water, depending on your desired level of thickness
  • Filter – I used a French Press but a nut-milk bag or a fine filter sieve would work as well.
  • Blender – any old blender will do!


  1. Soak the oats for about 15 minutes. This help removes some of the sliminess that comes with homemade oat milk. Rinse and drain the oats.
  2. Add rinsed, soaked oats to the blender and then add the corresponding amount of water – 2 cups for thicker oat milk (similar to the texture of Earth’s Own Oat Milk) to 4 cups for thinner oat milk (think, the consistency of skim milk).
  3. Blend for about 1 minute. The oats will be blended extremely fine at this point.
  4. Filter the mixture through a fine mesh sieve. I used a French Press which was an extremely slow process but does the job! You will have to depress the plunger multiple times in order to filter the entire mixture.
  5. Keep refrigerated. I have kept my oat milk in the fridge for up to 5 days with no issue. Some settling will occur, so make sure you shake prior to use.
  6. Don’t know what to do with the leftover oat mixture? Add a bit of maple syrup and cinnamon, heat it up, and you have yourself a warm bowl of oatmeal! 🙂
Note:  Some recipes also ask for a sweetener, such as 1 tablespoon of maple syrup. I wanted to keep my oat milk as simple and natural as possible so I opted out of adding it. If you add the sweetener, I would also add a pinch of salt to balance out flavours.

… And that’s it!

I have to admit, this is nothing like the Earth’s Own version that I love. It is not nearly as sweet (although the Earth’s Own version does not list sugar in the ingredients either). Not the greatest in coffee but it works just as well as store-bought when used in baking or with cereal. So the next time you run out of milk when your cereal craving hits, bust out the oatmeal and blender and have at it!

TL/dr – oats, blender and water  are all that you need to create your own oat milk at home!
