Oat Milk Mango Smoothie

This oat milk mango smoothie is made using frozen mango, oat milk, bananas, almond butter and lemon juice. It’s a perfect healthy breakfast or quick filling snack that’s kid-friendly and easy to prepare.

I wanted to share with you guys a super simple smoothie recipe that I’m really in love with. Simple enough that it takes less than 5 minutes between the time I grab a bag of frozen mango and pour myself a fresh tropical glass of smoothie.

And somehow, this smoothie has an amazing effect to get me in a healthy eating mindset. I mean, starting the day with a sunny nourishing smoothie seems to help resist the frosted brownies later. Usually. Unless you run into these black bean brownies, then you are good.

This recipe is also a good one if you are just starting out making smoothies. It only uses a few simple ingredients, the flavors are super smooth and the oat-banana-mango combo makes it naturally sweet.

Why use oat milk when making smoothies

Why is everyone going bananas about oat milk? Isn’t just the same as all the other dairy-free milks? Not quite.

I have expressed my deep love for oat milk before when sharing my review of The Oat Milk Cookbook. Since then, I’ve been using it more and more, especially when making smoothies. But, why?

On top of being nut-free (shout out to all the school kids parents!), gluten-free (make sure you read the label) and soy-free, oat milk creates a thick and super creamy texture to smoothies. Oat milk also has great flavor of its own, slightly nutty and naturally sweet, which is perfect when making fruit smoothies.

But what also makes oat milk valuable in the smoothie department is the fact that it is jam packed with fibers and contains lots of vitamins and minerals (some nutrients are lost from processing the raw oats into oat milk, but most store-boughts are enriched). This article “Oat Milk: Nutrition, Benefits, and How to Make It” will give you more detailed information about the health benefits of oat milk.

There is a measuring cup containing dairy-free milk with some rolled oat on the table.

Which oat milk to use to make this mango smoothie

As much as I love to make my own vegan milks (especially these strawberry almond milk and chocolate cashew milk), I will most of the time grab a container at the store. It’s simply more convenient and I haven’t had any luck at making a homemade oat milk that I love so far (the texture can become quite slimy if you do not make it properly). Check out this homemade oat milk recipe from Love and Lemon if you want to try making it yourself.

The oat milk I use is from Oatly. I love its super smooth and non-viscous texture and the fact that it is fortified with vitamin B12 (important when limiting your animal protein intake).

Showing are the ingredients to make a frozen fruit drink. There are mango chunks, dates, a banana, almond butter, oat milk and half of a lemon.

What you will need to make this oat milk mango smoothie

  • Oat milk. I use oat milk from Oatly. If you follow a gluten-free diet, read the label to make sure the milk is certified gluten-free.
  • Frozen mangos. You can use fresh mangoes, but try to chop them and freeze them first before making this recipe. This will help create a cold and refreshing smoothie.
  • Banana. Amazing to create a creamy texture and bring natural sweetness. Also, just like in this chocolate banana milkshake, you can use frozen ones to make it even creamier.
  • Almond butter. Brings healthy fats and helps create a rich and silky smoothie.
  • Lemon juice. The mango, banana and almond butter can be super rich when combined all together and the lemon juice adds a nice zesty flavor to balance out the richness.
  • Sweetener of your choice. This is optional and will depend on how sweet your fruits are, but I love blending medjool dates when making smoothies. Maple syrup or agave nectar work well too.

How do you make a oat milk mango smoothie

Simply toss all the ingredients in the blender and blend until super smooth.

I recommend to taste before adding any sweetener to your smoothie, since the sweetness will vary a lot on how sweet your fruits are.

Also, if you do not have a high speed blender, then use maple syrup instead of the dates.

Recipe variations

I love how smoothies can be versatile. You can use this recipe as a base and swap away!

  • Make it green: if you want to venture into the world of green smoothies, then add a large handful of raw baby spinach or kale to the blender.
  • Make it more filling: if you want to be sure you won’t be hungry for a while, then add raw oats (1/4 to 1/2 cup) to the mix before blending. If it makes your smoothie too thick, then add extra oat milk.
  • Make it nut-free: swap the almond butter for sunflower or pumpkin seed butter.
  • Make it higher in protein: add a hint of hemp seeds or chia seeds.
  • Make it zesty-er: mango pairs very well with orange juice, feel free to swap a portion of the oat milk for some.
