Over a year ago, I was ordering a matcha latte when I requested nut milk. The barista gave me an option of a few dairy-free alternatives, including oat.
It was so delicious and I loved how much creamier my matcha latte tasted. Since then, I’ve been making my own.
What is oat milk?
Dairy-free milk made with oats is great for people who have allergies to soy or nuts. It’s a great alternative for those looking to cut down on their dairy-intake or follow a vegetarian or vegan diet.
You can use it just like you’d use other types of milk, in coffee, smoothies, lattes, or baking. It has a creaminess that froths beautifully for coffees and lattes. In recent years, it’s become increasingly popular in coffee shops.
Making your own oat milk at home is quick, easy, and affordable. You know exactly what’s going in your milk and get to adjust the level of sweetness.
Ingredients you’ll need
You’ll need the following two ingredients to get started:
- Old-fashioned rolled oats: Be sure to use old-fashioned rolled oats, not quick-cooking oats. These are found in the bulk or packaged section of most grocery stores these days.
- Salt: Just a pinch.
- Water: For both soaking and blending
How to make oat milk
1. Soak the oats: This will make it easier for the oats to blend, especially if you don’t have a high-speed blender. Once they’ve soaked, the oats will plump up. Drain.
2. Blend the oats: Combine the oats with 3-4 cups of water in your blender. Blend for no more than 1 minute if using a standard blender. However, if you’re using a high-speed blender, you only need to process them for 30 seconds.
3. Strain: With a fine sieve, a double layer of cheesecloth, or a nut milk bag, strain the milk. Note it will separate so be sure to give it a swirl. If you’d like to add more sweetener, feel free to add a sweetener of your choice.
Pro tip: Avoid slimy oat milk by limiting the amount of time you blend it.
Storing for later
Store your homemade milk in a glass bottle with a lid. To avoid making a mess when pouring the milk into the glass bottle, either use a funnel or pour it back into the blender first.
Store the milk in the refrigerator for 3-5 days. Be sure to shake well before using it has the tendency to separate.
Top tips and flavor variations
Here are some fun ways of adding flavor to your homemade oat milk:
- Vanilla extract: Add vanilla extract to add a versatile vanilla flavor. You can do this when blending up the oats with the water and salt.
- Add fruit: Blend with fresh or frozen strawberries to make strawberry milk or a strawberry smoothie.
- Chocolate milk: Make chocolate milk by adding cacao powder or unsweetened cocoa powder. Blend and voila.
- Turmeric: Add turmeric and a few other ingredients to make a turmeric latte.
- Matcha: Add matcha to make a delicious matcha latte.
