Start by measuring out all your ingredients.

In a high-speed blender, combine the rolled oats and water. Blend on high for about 30 seconds, just until the mixture is smooth.

Add the brown sugar, vanilla extract, and a pinch of salt to the blender. Blend for another 10 seconds to combine well.

Using a fine mesh strainer or a nut milk bag, strain the blended mixture into a large bowl.

If using a nut milk bag, gently squeeze to extract as much liquid as possible.

Pour the strained oat milk into a clean container. Seal it tightly and store it in the refrigerator for up to a week.

Before using, give the oat milk a good shake.

Use your homemade oat milk in coffee, smoothies, or simply pour it over cereal.
