Start by adding the 1/2 cup of rolled oats, 3 cups of water, 2 teaspoons of real maple syrup, 1/2 teaspoon of vanilla extract, and 1/8 teaspoon of salt to your blender. Blend the mixture on high for about 30 seconds to 1 minute. You want to break down the oats without over-blending, which can make the oat milk too thick, resulting in slime.
Place two layers of cheesecloth over a large bowl. I find that securing the cloth with a rubber band or clips around the bowl helps to keep things steady. Slowly pour the blended mixture onto the cloth, allowing the liquid to filter through into the bowl below.
Once strained, leave the oat milk to strain, cover the bowl with plastic wrap and refrigerate overnight.
The next day, remove the cheesecloth and discard the oat pulp (or keep it for smoothies). Give the oat milk a stir before using it. Remember to shake or stir well before each use, as oat milk tends to settle when stored.
Keep any leftovers in the refrigerator. It will stay fresh for about 4-5 days.
How to turn Oat Milk Recipe into Creamer
You can use oat milk as is for creamer, but some people prefer a thicker version. Here is my variation for that. Please note that the ingredients change slightly and are noted in the instructions. This recipe makes about 1 to 1½ cups creamer.
In your blender, combine 1/2 cup rolled oats, 1 cup cold water, 2 teaspoons maple syrup, 1 teaspoon vanilla extract, and 1/8 teaspoon pinch of salt. If you want an extra creamy texture, add 1 tablespoon of coconut oil or 1-2 tablespoons of cashews. Blend on high for 30-45 seconds until the mixture is smooth and creamy.
Strain the mixture using a fine mesh sieve, nut milk bag, or cheesecloth to remove any oat pulp. Do not overly press pulp as it can create a slimy texture as starch releases.
Pour your creamer into an air tight jar and store it in the refrigerator. Shake well before each use, as the ingredients may separate over time. Keep for 4-5 days.
Notes
Oat milk is not naturally sweet or full of a particular flavor. Please experiment to find the perfect flavor for your usage.
