I love any type of plant-based milk. Almond milk, hazelnut milk, oat milk…. However, lately I’m drinking a little bit more oat milk so I switched up my routine of making only almond milk to also making my own oat milk. I’m going to show you how I make my own creamy oat milk with only two ingredients: oats and water.

There are a few moments in the day I like to add a splash of ”milk”. When I’m making a porridge I love to add some milk to make it extra creamy. But also smoothies with a bit of milk are very delicious. And let’s not forget my daily power drink (I’m showing the recipe often on my Instagram stories) that always starts with heating up some almond- or oat milk.

How To Make Oat Milk

The more oats you use the creamier the milk will be and the better you will need to shake the milk before using it

A nut milk bag is a way to strain your milk after blending it and it will make your oat milk smooth

You don’t need a nut milk bag. You can skip this step. Only blend the oats and serve/store for later.

The more water you add the more the milk will be like the store-bought versions since these contain a good amount of water

There is no need to waste the left over oats/pulp after using a nut milk bag. You can add it to your smoothies to get in that extra fiber, but you can also use it to make for example cookies (it also freezes very well)

This recipe is a basic recipe for a oat milk. For this recipe you will need 3 cups of water (750 ml to 1000 ml), but I would suggest you to try it and add more water until you get the taste and thickness you’re looking for. I noticed this can be very personal.

 Homemade plant-based milks are easy, fast and fun to make and you’ll safe a bit of money too. Only 2 ingredients needed!

I usually like to make my oat milk unsweetened since I use it in other recipes so I prefer the taste to be neutral for either savory or sweet recipes. However, if you like your milk sweet feel free to add any sweet ingredient that you like. You could add for example a date when the oats are blending. I sometimes like to add to the milk (once all done) a dash of cinnamon, vanilla and/or a dash of ground cloves.

  1. It turned out amazing! Thank you so much for this recipe! I was wondering if you hace a recipe to make the cookies with the leftover oats. Thanks again!

    • Hi Paola,

      I’m so glad you liked it! The most simple recipe I like is to mix it with some date syrup, flatten it like a cookie and bake it in the oven 🙂
