This homemade oat milk is super creamy, healthy and nutritious. You only need 4 ingredients, it’s ready in 15 minutes and tastes so good!


  • 1 cup oats (100 g)
  • 34 cups water (750 ml-1 l), I make my oat milk using 4 cups or 1 liter
  • 1 tsp vanilla extract (optional)
  • 12 tbsp maple syrup or 12 Medjool dates (optional)
  • A pinch of salt (optional)


  1. Soak the oats in water for at least 30 minutes. I usually soak them overnight, but that’s not necessary.
  2. Drain the oats and rinse them. Discard the soaking water.
  3. Add the oats, 3 to 4 cups of clean water (750 ml-1 liter) and all the remaining ingredients to a blender and blend until smooth. Add more or less water depending on how thick you like your oat milk.
  4. Strain the milk using a cheesecloth, a strainer, a napkin or a nut milk bag.
  5. Store in an airtight container in the fridge for up to 5 days.


  • You can use 1-2 Medjool dates (double the quantity if they are Deglet Nour) or any other sweetener if you like your milk sweet.
  • I usually make unsweetened oat milk so I can use it to make savory and sweet recipes.
  • Salt is optional, but it enhances the flavour.
  • To make the milk, use 3 cups of water (750 ml), try it and then add more water until you get the taste and thickness you’re looking for.
