Oat milk is the ideal beverage out there for those who prefer a creamier plant-based milk. We’ll give you some tips and tricks for making it yourself using our homemade oat milk recipe! 

This plant-based milk is often touted as the healthiest and most sustainable options among all the milk alternatives, however most store bought oat milk contains emulsifiers and added sugars. It’s also important to keep in mind that though it’s commonly referred to milk, oat milk doesn’t naturally contain any calcium. On the plus side, it also doesn’t contain any lactose, soy, or milk protein and it’s free of cholesterol.

This sustainable recipe for homemade oat milk uses organic rolled oats because rolled oats work best. When purchasing ingredients, be sure to look out for organic products grown in the USA. This not only ensures shorter transport routes, it helps to support local farmers. Using the resources available from your own country is one of the easiest ways to lead a more sustainable lifestyle!

How to Make Homemade Oat Milk

Ingredients

  • 1 cup organic rolled oats 
  • 3 cups water
  • pinch of salt 
  • 1 tbsp maple syrup (optional) 

Instructions

  1. Add oats, water, salt and maple syrup (if using) to a blender, and place the lid on top.
  2. Blend the mixture for approximately 30-45 seconds until it is mostly combined. Be cautious here because over-blending can make the oat milk slimy! 
  3. Do a taste test to make sure that you’re happy with the flavor —  you can always add a touch more maple syrup if you need to! 
  4. Strain the mixture into a large bowl or pitcher using a thin towel (or even a clean t-shirt). You’ll want to double strain it to ensure all the sediment is removed. Tip: Don’t let those oats go to waste — add them to oatmeal cookies, smoothies, or even use them as a soothing face mask.
  5. Transfer to a sealed container and place it in the fridge. On average, it will last between 5-7 days. 

Flavored Oat Milk Ideas

One of the best parts about making your own plant-based milk is the option to customize it. If you want to jazz up your morning routine, consider adding the following ingredients to our homemade oat milk recipe:

  • Chocolate: add 2 tbsp of fair trade cocoa powder
  • Very Berry: add 1 cup of mixed, seasonal berries – bonus points if you grow them yourself!
  • Vanilla: add 1 teaspoon of vanilla extract

How to Avoid Slimy Oat Milk 

One of the biggest complaints against making homemade oat milk is the fact that it can easily turn out to be quite slimy. We have some tricks to help avoid that: 

  • Use ice cold water for blending, as heat makes oats gummy and starchy. 
  • Avoid over blending — the absolute maximum you should blend your oats for is 1 minute.  
  • Strain well, a double strain works best. 
  • Don’t over-squeeze when straining the liquid out. 

Using Oat Milk

For those who have never tried it, oat milk tastes surprisingly similar to cows’ milk — it’s just slightly sweeter and with a bit of an oat-y aftertaste. Because of this, it makes a great alternative to cows’ milk in many recipes. You can pretty much use it as a 1:1 substitution for regular milk. Use it to make extra creamy oatmeal, in your coffee, to make chia pudding, or in your baked goods. Why not try adding it to some of our recipes:
