This healthy chocolate mango smoothie is ultra rich and creamy, super flavorful and packed with nutrients, such as antioxidants, vitamins and fiber. It is vegan and dairy-free, plus made without refined sugar. Makes for a nutritious breakfast, snack or even dessert!

My favorite kinds of smoothies are the decadent, silky and scrumptious ones that also qualify as dessert.
This peach pineapple smoothie and this chocolate strawberry smoothie are great examples of healthy drinks that find their way into the dessert territory in our house.
And this is how this healthy chocolate mango smoothie came to life: I was looking for a sweet treat to complement my meal while still being wholesome, full of flavor and fun.
This is a 4-ingredient simple smoothie recipe made 100% vegan and without dairy products. Plus the optional addition of a sweetener, depending on how sweet your mangoes are.
I also included a sneaky ingredient to make it even more substantial: rolled oats. The whole grain makes the smoothie packed with fiber and healthy fats, plus more filling and thicker.
As seen in my banana chai smoothie recipe, blending oats in smoothies creates the most creamy and rich texture while adding more natural sweetness to your drink. It also can help you stay full longer, which is great if you enjoy it for breakfast.

Ingredients you will need
- Rolled oats: you can use both old-fashioned oats and quick-cooking oats for this recipe. Rolled oats add extra fiber and help thicken this smoothie.
- Frozen mango: frozen mango is better for making this smoothie compared to fresh mango to keep the drink frosty and thick. It is also more convenient and budget-friendly than using fresh fruit.
- Plant-based milk: I used oat milk from Oatly, but you can use any kind of dairy-free milk you like, such as almond milk (delicious nutty flavor), coconut milk (for a super creamy smoothie and higher in calories, great for growing kids), soy milk (higher in protein) or cashew milk.
- Unsweetened raw cacao powder: I prefer cacao powder (more antioxidants, less processed) compared to cocoa powder, but both will work. I used 2 heaping tablespoons, which gave this smoothie just the right amount of chocolate flavor for me, but fell-free to add more.
- Optional: sweetener. I do not include extra sweeteners in most of my smoothies since the fruits normally add enough sweetness. But in this case, since we are adding some raw cacao powder, you may want to add a sweetener to compensate for the natural bitterness from cacao.

How to make a chocolate mango smoothie
This smoothie comes together within 10 minutes. There is an extra step to soak the oats for the best results, which can be as quick as 5 minutes.
If you have a high-speed blender like me, then you may skip that step, although I still prefer to soak them briefly to help tenderize the grain and blend them to a smoother consistency.
Soak the oats
To your blender, add the rolled oats and the plant-based milk. Make sure the grain is all well covered by the milk and then, let it soak for 5-10 minutes.
Blend
Once the oats are done soaking, then blend on high for 20-30 seconds. This will also help create a super smooth texture.
Then, add the raw cacao powder and the frozen mango chunks, then blend on high until smooth.
Adjust flavors
Taste the smoothie right in the blender before serving. You may want to add sweetener and also, if your smoothie looks too thick for you, you can add an extra splash of milk, then blend again. Repeat until desired consistency.
Pour in your serving glass and enjoy!




Helpful tips
- I wouldn’t recommend skipping on soaking the oats. Even 5 minutes will make a difference in pulverizing the grain completely. I have a high-speed blender and I still do that extra step, it is worth it. If you do not have a high-speed blender, then you could use quick-cooking oats and even soak for 15 minutes.
- As mentioned above, cacao powder is a little bitter, so taste your mango chocolate smoothie mixture to see if it needs a sweetener or not. You could add a splash of maple syrup or even a banana to balance the bitterness, if needed.

Serving suggestions
Enjoy the smoothie right away and garnish with more chopped fruit and a dust of raw cacao powder. You can try to chop the fruit super small so they can go through the straw.
If you have some dark chocolate, you can also shave some over the smoothie for more flavor.
More topping ideas include:
- Desiccated coconut
- Chia seeds
- Cacao nibs
- Hemp seeds
- Vegan chocolate syrup
- Mini chocolate chips
You can also easily make a smoothie bowl! In that case, make sure to keep your smoothie on the thicker side (using frozen fruit and not adding too much milk) and then scoop into a bowl. Garnish with more fruits, seeds/nuts, granola, nut butter, etc. Enjoy with a spoon!
Healthy smoothie boosters
You can also add extra ingredients to your smoothie to boost it with more nutrients or flavors depending on what you are looking for. Here are a few of my favorite boosters:
- Nut butter: add a spoonful of peanut butter or almond butter to make your smoothie richer in flavor and texture, but also, to add extra plant-based protein.
- Greens: a handful of baby spinach or kale would add a whole lot of nutrients to your smoothie without interfering with the flavor or color that much. Or add arugula for a mild peppery flavor!
- Seeds: I often add some chia seeds, flax seeds or hemp seeds to the blender when making a smoothie. This adds a generous amount of healthy omega-3 fats, but also some more fiber and protein. This is a great addition if you enjoy this drink as your breakfast.
- More fruit: feel free to add some strawberries, bananas or pineapple as well. Extra fruit can make your smoothie sweeter naturally.
- Protein powder: you can add a scoop of vegan protein powder to make a mango chocolate protein smoothie! I like the plant-based pea protein kind and use a vanilla or chocolate flavor for the best result.
- Extra flavoring ingredients: a small amount of vanilla extract or cinnamon can also enhance the overall flavor of your smoothie.

FAQs
I recommend using frozen mango to give your smoothie a thick and chill effect. If you only have fresh ripe mangoes, then you might want to freeze chopped mango the night before. If you want to make it right away using fresh mangoes, then you might want to also include a few ice cubes or a frozen banana in the blender.
This smoothie is best when enjoyed right away. Over time, the flavor won't be as fresh and the smoothie will lose its frosty delicious consistency.
