Blend together the oats and cold water for about a minute.
Using a super fine mesh strainer, cheesecloth or nut milk bag, strain out the milk from the oats into a bowl. Pour into a jar or pitcher.
Drink straight, pour over cereal, add into your smoothies, etc!
Oat milk can sometimes become thick and a different texture if heated up - I recommend testing your oat milk and heating a little up in the microwave or on the stove to see if you mind the texture. I actually don't mind it in my coffee but have heard that some people are not a fan.
