Homemade Vegan Milk – under 1$ per bottle!

There was a period in which I avoided vegan milk altogether because it was so expensive here in Copenhagen (3$ for 1). I guess, if I used all of it, it would be alright, but I often found myself being unable to use up all of it when I was living alone and ended up having to throw it out.

You can make a wide variety of plant milks at home but if you are looking to save up, oat milk might be the most budget friendly alternative out there. It is oats and water, blended together and strained! It really is that simple and it gets better. You can make different variations based on your taste!!

If you have a Nutribullet or another high speed blender

This process is so simple that I really wish I knew it earlier – can only imagine how much I would have saved up!


  • 1 cup rolled oats
  • 4 cups water (I use sometimes 5 to avoid it becoming thick)
  • a pinch of salt

For different varieties of oat milk

  • 2 tablespoons cacao powder (chocolate milk) – you can add 1 tablespoon of sugar to make it sweeter or any kind of syrup you like.

  • any kind of fruit for fruit milk
  • any other flavor you want to try.
ingredients for homemade oat milk

How to make plant oat milk:

  1. Add all ingredients you want to use for your milk to a blender.
  2. Blend on high speed for around 5-10 seconds. * I have seen people recommending blending it for 30 seconds to one minute but I find that if you have a high speed blender, 30 seconds will make your milk slimy!
  3. Strain your milk through an old t-shirt, unused thin sock (my favorite), some cloth that can strain, strainer or anything else you can use to strain it with. *Double strain for best result.
  4. Keep in the fridge for up to 4-6 days.

What can I use this vegan oat milk for?

You can use it for your oatmeal, cereal, coffee or anything else that you enjoy cold. I don’t recommend heating it, as it might become very slimy and gooey. This milk is to be enjoyed cold.
