I wanted to share with you guys a super easy smoothie recipe that I'm really in love with. It looks pretty straight forward and almost too simple to be that good, but you got to trust me, this smoothie is the creamiest and the most flavorful smoothie you will have in a while.

It is not that thick, though, but so unbelievably rich and dreamy. Almost like a thick cream. There is something magical into blending frozen banana to a liquid!

This recipe also is 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 milk-banana-date combo makes it naturally pretty sweet. It feels like a delicious drinkable dessert! Plus, it can be done within minutes.

Great to enjoy for breakfast as it will give you a nice boost of energy. I would also totally love it after working out to refuel. This smoothie also is a favorite of my kids: apart from the bananas, there are no fruits to bring any sourness, which makes this smoothie taste pretty much like caramel.

Hope you give it a try! ❤️

Why use oat milk when making smoothies

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, gluten-free (make sure you read the label) and soy-free, oat milk creates a thick and super creamy texture to smoothies (swap the almond butter for a seed butter for a nut-free smoothie). I actually find oat milk to be the closest in consistency to regular milk! I use oat milk also when making myself a matcha latte as it froths so well.

Oat milk also has great flavor of its own, slightly nutty and naturally a little sweet, but overall mild in flavor which is perfect when making any kind of smoothies.

But also, oat milk is jam packed with fiber 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 should I use

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). I would highly recommend getting an unsweetened oat milk though as it is already naturally a little sweet!

Ingredient list

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 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.
Medjool date: Can be omitted if you don't want it to be too sweet (the banana might be sweet enough), but I love blending medjool dates when making smoothies! Maple syrup or agave nectar work well too, but I love the fact that dates are unprocessed and also provides extra fiber to the drink. Large and soft medjool dates (found in the produce section at the grocery store) work better than dry dates.
Vanilla extract: totally optional, although it adds an amazing dessert-like flavor. Could also be swapped for a pinch of cinnamon.

Showing are the ingredients needed to make this recipe.

How to make this oat milk mango smoothie

Simply toss all the ingredients in the blender and blend until super smooth. I like to first pour the milk in and then the rest of the ingredients so it blends easier.

I also recommend to taste before adding the date if you don't like smoothies that are super sweet.

Helpful tips

Always shake or stir well the oat milk before using. Solids tend to sink at the bottom while resting in the fridge, whether it is store-bought or homemade!
Although I used a high-speed blender (Vitamix) to make it, this smoothie recipe can easily be made using a regular blender as well. In this case, you might want to soak the date in boiling water for a few minutes before blending to help crushing it. OR, add a little maple syrup as needed.
You can add a handful of ice cubes to help chill and thicken the smoothie if needed.

Recipe variations

I love how this smoothie is simple and so versatile. You can use this recipe as a base and add some more goodness to it. Here are a few ideas for inspiration:

Make it green: add a large handful of raw baby spinach or baby 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 (¼ to ½ cup) to the mix before blending. If it makes your smoothie too thick, then add extra oat milk. I also recommend to first add the oats to the blender, then pour the milk over and wait for 5 minutes before adding the remaining of the ingredients. This will allow the oats to soften and prevent a gritty texture.
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. OR, if you have vegan protein powder, then add some!
Make it zesty: feel free to add a squeeze of lemon juice to brighten up the flavor a bit.
Make it fruity: you can definitely add a handful of frozen fruits such as berries, mangoes, peaches, cherries, etc. If the frozen fruits makes the smoothie too thick and more difficult to blend, then add an extra splash of oat milk.
