What is oat milk?

Oat milk is the newest “trendy” plant-based milk that is growing in popularity. You may have even seen some cafes serving up oat milk lattes, or see oat milk on the shelves now at your local grocery store.

This milk is simply oats, either regular or steel cut, soaked in water, blended and strained. The left over fluid is the “milk”. While the majority of the fiber, protein and nutrients remain in the oats even after being strained, oats absorb water better than nuts so when blended very well, more of the oat itself passes into the milk making it creamier than most milk alternatives.

Why oat milk instead of almond, coconut and others?

Oat milk is gaining popularity for good reason! While almond, cashew, coconut, hemp…the list goes on, are good for you, oat milk has some winning characteristics.

First it is not made from nuts, so anyone with a nut allergy can enjoy this milk alternative. Second, oats are high in fiber. Compared to all other milks, even dairy, oat milk provides far more fiber. Third, oats contains B vitamins thiamin and folate, and minerals such as magnesium. These nutrients are typically deficient in adults, especially women, so any way to add these into our diets the better! Lastly, oats are cheap. While oat milk may only be a few cents cheaper in grocery stores, making this simple homemade oat milk at home will sure save you money!

How to make homemade vanilla oat milk

All you need to create oat milk is essentially a cup of oats, water, and then whatever add-ins you like to flavour it. I’m serious, THAT’S IT.

I flavour my oat milk the same way I enjoy to flavour my almond milk: with Medjool dates and vanilla. This gives the milk a slightly sweet taste to it with a hint of vanilla flavour. Though if you prefer, you can simply stick to the oats and water and leave it unflavoured if you prefer to use the oat milk in some savoury recipes.

Now, a few handy tips…

Oat milk can have a slight slimy film to it, so make sure to rinse your oats very well before blending this up to avoid this. I also recommend using large flake oats or whole oats as opposed to quick oats in this recipe.

This homemade vanilla oat milk is:

  • A great dairy-free milk alternative
  • Quick & easy to make
  • budget friendly
  • Has calcium magnesium and iron

From my experience oat milk doesn’t store as long as almond milk does and will hold up well for 2-3 days in the fridge. I also recommend to ALWAYS keep your plant-based milk stored inside your fridge, as opposed to in the door of your fridge. The temperature of the fridge door is warmer than inside the fridge and you’re milk won’t last as well if stored there.

A healthy plant-based milk made from oats




  1. Place the oats in a bowl and cover with some water. Let sit for 15 minutes.
  2. Drain and rinse the oats thoroughly. (Make sure to rinse well to remove any slimy film!)
  3. Add the oats, 3 cups of water, dates, vanilla and salt to a high-speed blender and blend for 30 seconds.
  4. Pour the mixture into your nut milk bag with a large bowl underneath to catch the milk. Push the liquid gently through the bag.
  5. Pour into a large jar or container and store in the fridge for 2-3 days.


Use gluten-free certified oats if needed

Strain your oat milk 2-3 types for extra smooth and creamy milk

Store your oat milk INSIDE the fridge instead of in the fridge door. This will help the milk keep longer.
