Oat milk is one of the hottest trends of the last few years. It’s dairy-free, vegan, and low in fat but has a creamy texture that works perfectly in coffee or cereal.

Rather than spending a lot of money buying packaged oat milk, here’s how to make it at home using simple ingredients without food additives.

Homemade Oat Milk Creamer Benefits

  • Oat milk is naturally nut-free and possibly less allergenic for some people than almond milk or other plant-based milk alternatives made from nuts. It’s one of my favorite dairy-free milk options. See my tips for starting a dairy-free diet.
  • Oats have unique nutritional properties and are high in fiber, B vitamins, and minerals.
  • Oat milk has a neutral and natural flavor; it’s non-offensive and blends in with whatever recipe you’re using it in, including coffee drinks or this delicious Oat Milk Hot Chocolate or Matcha Coffee.
  • The rich oat cream makes a wonderful dairy-free coffee creamer that is free from gellan gum, cane sugar, sunflower oil, pea protein, canola oil, or other additives that are often added to the pre-made milk non-dairy milks and non-dairy creamers. See why Coffee Mate is unhealthy.
  • Best of all, this recipe uses steel cut oats which helps reduce any slimy texture that can come from making homemade oat milk. This is a winner that you’ve got to try.

In short, this easy recipe for oat milk is perfect for a no-dairy diet and as your new favorite coffee creamer or milk alternative. The best part is that it’s easy to make. It’s sure to become your new favorite nondairy creamer.

Ingredients You’ll Need

INGREDIENTS with how to make oat milk creamer

Steel cut oats can be found in the cereal or grain section of most grocery stores (I like using the gluten-free Bob’s Red Mill steel cut oats).

You can also use rolled oats, but I recommend using steel cut oats to help reduce the slime that can come when blending oats and water.

You do need to soak the oats before blending them (see the recipe steps and recipe card below for all the details).

Filtered water gets blended with the oats for this homemade oat milk creamer recipe. I recommend filtered cold water as the best option to help avoid any chlorine flavor to your oat milk.

Maple syrup adds just a touch of sweetness to this creamy dairy-free beverage. You can also use a pitted date for a little sweetness, if you prefer.

Sea salt helps bring together all of the flavors.

Please see the recipe card at the end of this post for the exact ingredients and measurements.

Recipe Steps

Making oat milk is similar to the process of making homemade almond milk where you essentially just blend the ingredients and then squeeze the liquid from the solids.

Let me show you exactly how to do it!

Step One

Soak your steel-cut oats in water for several hours.

Rinse the soaked oats in a strainer or fine-mesh sieve.

Please see the recipe card at the end of this post for the exact ingredients and measurements.

Step Two

Combine the soaked and rinsed oats and three cups of water in a high-speed blender (like a Vitamix) and process for 20-30 seconds.

Step Three

Pour the milk through a fine mesh strainer and use a spatula to gently push it through. You can also use a nut milk bag.

Step Four

Pour the milk back into the blender and add the sea salt and maple syrup.

Blend a second time for just about 5-10 seconds to make sure the mixture is completely combined.

Transfer the oat milk to a container with a lid.

Use immediately in your hot coffee or oat milk latte, or save any leftovers in the refrigerator for up to 5 days

Oat Milk Coffee Creamer Recipe Tips

  • If you don’t have maple syrup, you can use one pitted date instead for a sweetener. If you want to use your oat milk for savoy recipes or you’re on a sugar-free diet, then just leave out any sweetener.
  • You can use your oat milk non-dairy creamer in savory dishes, too! Just stir a few tablespoons into a hot soup for a creamy, dairy-free heavy cream option.
  • Use certified gluten-free oats to make this recipe gluten-free.
  • Filtered water helps prevent any chlorine taste.
  • Don’t overblend the oats and water to help prevent it from getting slimy.

Recipe FAQs

Can I use rolled oats for this recipe?

Yes, but they tend to create more of a slimy texture than steel cut oats. If you use rolled oats, you don’t need to soak them first.

Do I have to use a Vitamix for this recipe?

It is best to use a high-speed blender to ensure that the steel cut oats get fully combined with the water. A regular blender may not get the milk as creamy as it should be.

Are steel cut oats the same as oat groats?

No, they are different. Use steel cut oats for this recipe.

Why does oat milk get slimy?

Oats are very high in soluble fiber which absorbs water. That means that when you blend oats, they have a high surface area to absorb water and create a slimy texture. It’s not actually slime, it’s just water and fiber mixed together. This recipe using steel cut oats can help prevent the slimy texture from occurring as much as the steel cut oats are not as finely cut as rolled oats.
