How To Make Simple Homemade Oat Milk

 How to Make Oat Milk

Making oat milk at home is so simple. This easy-to-make recipe makes a batch of smooth & creamy oat milk.  Perfect for adding to coffee, cereal, and all your dairy-free recipes.

 If you are looking for plant-based milk that is creamy and delicious, then oat milk is an excellent option. What I like about oat milk is it is a perfect dairy-free milk option for those with nut allergies. Oat milk is my go-to option when I am baking treats that my older daughter will be eating. My daughter has a nut allergy and I have a dairy allergy so I have to be careful with my baking when she comes over to visit. 

 What I love about homemade oat milk, is how quickly I can make a batch of oat milk. Unlike other non-dairy milk recipes, oat milk does not require any special equipment like nut milk bags. Making oat milk at home also does not require long soak times like homemade almond milk. The preparation of oat milk takes less than 30 minutes, so you can make oat milk quickly.

The many uses of oat milk

  Have you tried oat milk? Oat milk is creamy and has a great flavor. Oat milk tastes great in coffee, cereal, and even can be used in recipes, making it a great milk substitute for dairy-free recipes. Oat milk is also used in vegan ice cream! My latest use for oat milk is in this Dairy-Free Iced Brown Sugar Oat Milk Coffee Latte that is similar to a popular coffee shop summer drink.

 Oat milk is fairly new to the plant-based beverage line in stores and may be hard to find in some grocery stores. It also may be more pricey than other plant-based milk choices. I am not sure why oat milk costs more to buy when oatmeal is cheaper than nuts. So being that I like saving money, I decided to learn how to make oat milk at home.

Homemade Oat Milk Is

+ Creamy

+ Plant-Based

+ Delicious

+ Smooth

+ Vegan

+ Dairy-Free

+ Easy To Make

+ Gluten-Free

+ Nut-Free

+ Allergy-Friendly

 What's not to love about homemade oat milk if you are looking for non-dairy milk that is allergy-friendly. When you use certified gluten-free oatmeal, nut milk is a good choice for those who have gluten issues and since it is not made with nuts, those allergic to nuts can enjoy DIY oat milk. I know that coconut milk is another nut-free plant-based milk but some people have sensitivities to coconuts.

 Making oat milk at home is super easy and other than needing oatmeal, you don't need to run out and buy any fancy high-speed blender. You can use a regular blender to make homemade oat milk at home. The other items that you need to make this delicious creamy homemade oat milk are ones that you probably have in your kitchen or don't cost that much to buy.

Items Needed To Make Oat Milk

+ Oatmeal ~ Whole rolled oats work best in this oat milk recipe

+ Sweetener ~ If you desire sweet-tasting oat milk. I like using maple syrup as it dissolves quickly

+ Water ~ While filter water is best, you can use tap water

+ Fine Mesh Strainer ~ If you only have a regular strainer, you can line it with a clean thin dish towel

+ Large Coffee Filters ~ To fine strain the oat milk

+ Blender ~ A high-speed blender works best but you can use a regular blender

 Should I Soak The Oatmeal?

 While I was searching for the best oat milk recipe, I discovered some recipes that had you soaking the oatmeal for 15 minutes and then rinsing. Other oat milk recipes did not require soaking of the oats. So I decided to make a couple of batches of oat milk to see if soaking made any difference in the taste or texture of the oat milk. I got the best results when I soaked the oatmeal for 15 minutes without rinsing the water. So soak the oatmeal in the water in the blender before blending.

Can I Use Oat Milk in My Coffee?

 I have found that homemade oat milk works best in cold coffee drinks. Speaking of coffee, have you tried Death Wish Coffee? It is the best coffee for cold coffee drinks as it is so bold in flavor. When I add oat milk to my hot coffee, it tends to curdle and get too thick. Maybe because I microwave my coffee after I make it or I tend to slowly drink my coffee. I am not sure the reason homemade oat milk curdles in hot coffee. So I recommend just using this oat milk in cold coffee drinks. 

Can I Use Instant Oatmeal Or Steel Cut Oats?

 From my research in making oat milk yourself, every recipe that I have seen, recommends using rolled oats for best results. So make sure to buy rolled oats and not instant oatmeal. That way your oat milk will be smooth and creamy.

Can I Use Regular Sugar To Sweeten The Oat Milk?

The reason this oat milk recipe calls for maple syrup is that it dissolves better in the liquid. Since this oat milk recipe uses cold water, regular sugar would not dissolve and your milk would have a grainy texture. You can try honey or agave to sweeten the oat milk but I think that maple syrup adds better flavor and is thinner, so it will dissolve better in the milk.

How to Use Oat Milk

 Once you’ve made oat milk, use it as you would dairy milk, cashew milk, or any other type of milk you like. I don’t recommend using it in savory recipes since it has an oatmeal flavor. I use this oat milk in my cold coffee drinks, cookie recipes, overnight oats, and other sweet recipes. Oat milk is perfect for dairy-free vegan recipes.

How To Make Simple Homemade Oat Milk

Yield: 4
Author: Mom Knows Best
Making oat milk at home is so simple. This easy-to-make recipe makes a batch of smooth & creamy oat milk. Perfect for adding to coffee, cereal, and all your dairy-free recipes.


  • 1/2 cup whole rolled oats
  • 3 cups iced cold water
  • 2 teaspoons maple syrup
  • ½ teaspoon vanilla extract
  • ⅛ teaspoon sea salt


  1. Combine the oats, water, maple syrup, vanilla, and salt in a blender for 30 seconds on high.
  2. Place a fine-mesh strainer over a large bowl. Pour the milk into the strainer.
  3. Let the milk slowly go into the bowl without pushing it any excess oatmeal pulp through. This will help your oat milk not be gritty or slimy.
  4. Strain again:  For extra-smooth oat milk, strain the liquid twice, discarding the leftover pulp both time. To remove the most grit, double layer 2 large coffee filters in your strainer.
  5. Pour the oat milk into a pitcher and store it in the fridge for up to a week.
  6. Tip: Unlike other dairy-free milk, don’t shake it when you go to use it. Instead, lightly stir it and allow any leftover oat pulp to settle at the bottom of the container. Then pour the creamy milk slowly into your cup, so the oat pulp stays out of your glass.

Can you use dates in this oat milk recipe instead of maple syrup? If so, how many would you recommend and what kind of dates?

Mom Knows Best said...

Yes you can. I would add 2 dates to the recipe for sweetness. The dates will make the oatmilk a darker color.

I have a big batch of oats from when I bought them to make oatmeal raisin cookies. They flopped so now I need to find a use for the oats. I think I'll have to make a batch of oat milk.
