Add all of the ingredients to a high-speed blender and blend until smooth for about 30 seconds. Pour the mixture through a sieve to remove any residue or unblended coconut milk.
Transfer to airtight sterilized storage jars or bottles and refrigerate immediately.
Storage: It will keep in a sealed container in the fridge for up to 5 days. Shake the jar/bottle well before serving as it will naturally separate in the fridge.
Notes
You can substitute the coconut milk for extra soy cream, which will give a slightly less creamy result.
This recipe will thicken in the fridge, which is perfect for serving over ice as that will water it down. But if you find it too thick/strong for your liking, simply water the mixture down with a little more oat milk.
