What is Oat Milk?

Oat milk is simply rolled oats and water blended together then strained to leave the pulp behind. The result is easy, creamy, DIY oat milk!

How to Make Oat Milk

To make oat milk simply add 1 cup rolled oats + 4 cups water to a high-speed blender and blend on high for 30-45 seconds. Then strain through a clean t-shirt or towel for best results.

We found nut milk bags let too much pulp through. Fine mesh strainers also let too much pulp through, so we don’t recommend using them.

This method yields creamy oat milk every time that’s perfect for adding to coffee, matcha, cereal, oats, baked goods, granola, and more!

Oat Milk FAQs

How do you make oat milk not slimy?

  • Over-blending can make the oat milk slimy in texture, which is why we recommend blending for about 30-45 seconds.
  • Soaking your oats can also make the oats more prone to sliminess. Just add to the blender with water and blend!
  • Sometimes heating your oat milk can make it become slimy, so we don’t recommend it. Good news: We have an oat milk recipe coming soon that’s inspired by Oatly Barista milk and is perfect for heating / frothing!
  • We recommend straining twice to remove any of that excess starch which can also lend to a slimy texture.
  • We recommend straining with a towel or clean t-shirt as nut milk bags and fine mesh strainers let too much pulp through.

Can you use steel cut or quick oats to make oat milk?

  • In our experience, rolled oats are the way to go. Steel cut oats are too unprocessed and make less creamy milk. Rolled oats are just right and make nice and creamy oat milk. And quick cooking oats are too finely processed and tend to create slimier oat milk.

How long does oat milk last?

  • Well sealed in the refrigerator, oat milk should last about 5 days. You’ll know it’s gone bad when it smells funny.

Why did my oat milk separate?

  • Separation is totally normal with oat milk and many other dairy-free milks. Simply shake well before use!

How do you get oat milk to froth?

  • Plain oat milk is less creamy, can often get slimy when heated, and tends not to froth well.
  • Barista blends are creamy and froth well largely because they contain a considerable amount of fat in the form of rapeseed [canola] oil.
  • If you’re looking to make frothy oat milk for adding to your favorite warm beverages, with healthier oils,  check out Cashew Coconut Oat Milk – Minimalist’ Baker’s Oil-Free Take Barista Milk! 2
  • This quick, 5-ingredient recipe is a blend of ingredients. Cashews create a creamy, rich base, a perfect complement to the flavor of oats. Coconut flakes round out the creamy texture while also adding a bit of natural sweetness.
  • Once blended, simply strain and watch the glorious stream of rich, dairy-free milk pour into your bowl.

Flavour Variations – simply add when blending to give your creamer a flavour boost.

  • pinch of sea salt as well as a pitted date for a bit of natural sweetness
  • vanilla extract
  • handful of fresh berries
  • cacao or cocoa powder

Oats themselves do not contain gluten, a protein specific to the wheat family of cereal grains, but oat crops often become cross-contaminated with wheat both in the field and during processing.

That means that the end products can contain traces of gluten. Cooks who are highly sensitive to gluten or have celiac disease should opt for oat products that are processed in wheat-free plants and labeled as certified gluten-free.

Oats also contain avenin, a protein similar to gluten that has been shown to exacerbate symptoms in a small percentage of people with celiac disease.
