I love oat milk because it’s smooth, creamy, blends well, and is rich in essential nutrients. Most oat milk is fortified with essential B vitamins, iron, calcium, and a host of other vitamins and minerals. Oat milk is also great because it contains soluble fiber which can help to lower cholesterol.
Curious about how to make your own oat milk? I got you covered. Scroll down a bit and I’ll break it down in case you want to get bonus points for creativity!
How to Make Oat Milk
While I love the convenience of being able to buy pre-made oat milk at the grocery store, sometimes I want to branch out of my comfort zone and make my own.
When making your own oat milk, you only need 3 ingredients:
- 1 cup whole rolled oats
- 4 cups water
- 2 teaspoons maple syrup or agave
Additionally, you can add a pinch of sea salt and 1 teaspoon vanilla extract, but these ingredients are optional.
To make your own oat milk, blend all ingredients on a blender on high for 30 seconds. Then, strain your oat milk through cheesecloth or a specially made nut milk bag.
Your freshly made oat milk will keep in an airtight container in your fridge for up to 5 days, or in the freezer for up to 3 months.
What You Need to Make an Oat Milk Smoothie
This oat milk smoothie could not be simpler. For this base recipe, I have chosen to add bananas and nut butter. When shopping for bananas, ripe is best! Just avoid any mushy or moldy ones.
For the nut butter, I chose peanut butter for my oat milk smoothie, but any nut butter would work great.
- Oat milk
- Nut butter
- Maple syrup
Now, as I said before, there are countless ways to mix up this smoothie and make it the most decadent, satisfying smoothie. Here are just a couple of my favorite add-ons:
- ½ cup of frozen berries: I prefer a combo of strawberries and blueberries
- 2 tablespoons cacao
- 1 tablespoon matcha
- 2 tablespoons Nutella (in place of nut butter, or alongside!)
- 1 scoop of vanilla protein powder
- Use almond butter and add ½ teaspoon almond extract
- 2 teaspoons cinnamon,1 tablespoon cacao, and ½ teaspoon cayenne for a spicy chocolate treat
How To Make an Oat Milk Smoothie
Combine all the ingredients in a blender. Reserve ½ cup of your oat milk and add it if necessary.
Then, pour your smoothie into your desired container, drink and enjoy!
Pretty simple right? In less than 5 minutes you’ll have a healthy serving of this creamy, smooth smoothie. This recipe reminds me of a milkshake—it’s that decadent!
Can I put oat milk in my smoothie?
You sure can! Oat milk can substitute liquid in any smoothie. I prefer it because it adds a pleasant richness and creaminess without imparting too much flavor.
What does oat milk taste like in a smoothie?
I think oat milk adds a smooth creaminess compared to most types of non-dairy milk. Its slightly earthy taste doesn’t impart too much flavor to the smoothie, making it an easy swap for other types of milk.
Is it OK to put uncooked oats in a smoothie?
Yes! Uncooked oats are safe to consume in your smoothie—in fact, they may fill you up faster and add in soluble fiber that’s good for your healthy gut bacteria. If adding in raw oats to a smoothie, consider blending them first before adding them, as this can help make the texture less noticeable.
I recommend adding ¼ cup of blended oats to your smoothie if you’re looking to add in more fiber or thicken your smoothie into more of a smoothie bowl consistency.
