Unsweetened oat milk is the perfect non-dairy milk. It has a mild flavor and works well in sweet and savory recipes. 

Plus, it’s so easy to make at home. All you need are oats, water, and a blender to make oat milk.

What’s The Best Type Of Oat To Use To Make Unsweetened Oat Milk

When it comes to making oat milk, the thinner the oat, the better. Old fashioned-rolled oats or quick oats are best for making oat milk. These oats have a thin texture that is easy to break down. 

Do not use steel-cut oats or whole-groat oats to make oat milk. These oats have a thicker texture. It will take longer for the blender to break down these oats, which could give the oat milk a slimy texture. 

Is It Cheaper To Make Your Homemade Oat Milk

It is much cheaper to make your own oat milk at home. I purchased a 42-ounce package of oats at $8.99. 

This recipe only uses 1 cup of oats. So it costs $1.83 to make 3 cups of unsweetened oat milk which is much cheaper than store bought oat milk.

Tips For Making Unsweetened Oat Milk 

Unsweetened oat milk is easy to make. But even the easiest recipe can become complicated. Use these tips to make sure your oat milk comes out perfect every time. 

Do Not Soak The Oats

Oats are absorbent. If you soak them in water first, they will absorb all of it. Your oat milk will have a slimy texture that resembles blended overnight oats. It’s better to blend dry oats. The oat milk will have a creamy texture that is not slimy. 

Use Cold Water

Always use cold water to make oat milk. If you use hot or warm water, the oat milk will have a sticky, slimy texture. 

Do Not Blend Oat Milk Too Long 

Blend the oats for 30 seconds. I know what you’re thinking; 30 seconds does not seem that long. You don’t want to over-blend the oat milk. If you blend it too long, the blender will produce heat, leading to slimy oat milk. 

Strain Your Oat Milk Twice

Once you pour the oat milk into the cheesecloth, let it drip slowly. Do not squeeze the oats in the cheesecloth to try to get the milk to come out faster. Your oat milk may come out slimy. 

Once the oat milk is strained, strain it again. Yes, it is extra work, but straining the oat milk twice is definitely worth it. It will give the oat milk a creamy smooth texture. 

Add A Sweetener

I chose to leave the oat milk unsweetened because I would be using it for smoothies and baked goods. However, you can add 1-2 tablespoons of maple syrup or a pitted date to give the oat milk a sweeter texture.

How To Store Unsweetened Oat Milk 

Store unsweetened oat milk in an airtight container like a mason glass in the refrigerator. The oat milk will last for 5 days. 

Why Did My Oat Milk Separate

If your oat milk separates, it does not mean it is spoiled. Spoiled oat milk will have a funny smell. 

The oat milk separated because it does not contain any gums or thickeners. These ingredients help the oat milk stay together. 

Since this oat milk recipe does not contain these ingredients, it will separate. There’s no need to worry. Shake the oat milk a few times, and it will be ready to drink or use. 

What Can I Use Oat Milk For

You can use oat milk to make so many foods. Use oat milk just like you use dairy or other types of non-dairy milk. You can use oat milk in smoothies, custards, soups, coffee, bread, cakes, tea, and so much more. 

I used oat milk to make a fever grass green oat milk smoothie, and it was delicious. You can also drink oat milk by itself. However, I’d recommend adding a sweetener and a bit of vanilla extract if you want to drink the oat milk straight up.
