DIY Oat Milk Recipe

Why make oat milk at home?

  • No additives – big brand oat milks nearly always contain additives of some sort. These can include unhealthy highly refined oils, preservatives and gums. With DIY oat milk, you are in control!
  • Environment – DIY oat milk eliminates the need for milk cartons which sadly don’t always get recycled. Not only this, but oat milk is 90% water, and so adding the water at home instead reduces transport emissions. Less trucks = less CO2.
  • Delicious – you can add whatever ingredients you like and adjust the recipe to your taste.
  • It’s fun!

DIY oat milk, if you are feeling lazy

If you love DIY oat milk, but don't want to go through all the effort every time.. then give our instant oat milk powder a go. Simply add water, shake, and enjoy! Plus, it has the benefits of homemade = better for environment, customisable, blah blah blah. Anyway, back to the recipe.

DIY oat milk represented by a spoonful of oats


  • 100g Oats
  • 1000ml Cold Water
  • Pinch of salt


  • Blender
  • Strainer cloth / muslin


  1. Fill a blender with 1000ml of cold water, and then add the oats and a pinch of salt.
    • You can use any type of oats, however we found regular rolled oats work best as jumbo oats take longer to blend.
    • Some recipes suggest soaking the oats prior to this stage, but we found regular dry oats work best.
  2. Blend for 30-45 seconds until smooth. Do not blend for too long otherwise your oat milk will heat up which can cause sliminess.
  3. Pour the blended milk through a straining cloth. If the milk doesn’t pass through, you may want to try a less fine strainer cloth.
  4. Give your oat milk a taste. If you like it au naturel then it’s ready to enjoy, but if you prefer sweeter or creamier milk then you can experiment with adding the ingredients below.
  5. Optional: if you like your milk sweeter, try adding some maple syrup or clear honey and blend. 2 or 3 teaspoons will make a big difference.
  6. Optional: if you like your milk creamier, try adding some cashew butter and blend.

If you want all the benefits of homemade oat milk but don’t want to go through the effort of making it every time, try our instant oat milk powder. Only 3 simple ingredients, plus added calcium and vitamin B12. Just add water and shake!


  • Why is my oat milk slimy?
    • You may have over blended the oat milk causing it to heat up. Try blending on a lower power or for less time. If you are still getting sliminess, then you can also try using a finer strainer cloth.
  • What can I do with leftover pulp?
    • This can be used to make porridge, simply add some water and oats.
  • The oat milk is too watery?
    • The strainer cloth may be too fine. If you are still having issues, try using slightly more oats with the same amount of water. In addition, try adding some nut butter and blending which will make it creamier.
  • Why has my oat milk separated?
    • This is natural – simply give it a shake before use.
