Mango Avocado Banana Smoothie with Oats and Peanut Butter

This mango, avocado, and banana smoothie comes together in one blender with oats, chocolate peanut butter, and a little honey. 

It’s filling enough to drink before a run or a workout, and the whole thing takes about five minutes once you have your fruit cut. 

I made this at the end of mango season, and I’ll be honest with you: the smoothie was good but not exactly what I wanted. The mangoes were sour, and I couldn’t achieve the sweetness from the honey as I wanted. 

So, I’ll also tell you what I’d change next time.

Ingredients

• One-quarter of a medium mango, cut into small pieces (fibrous parts removed)
• Half a banana, roughly sliced
• 1.5 tsp avocado
• 1 tsp oats
• 1 glass of milk (around 250 to 300ml)
• 1 scoop chocolate high-protein peanut butter
• Honey to taste (I used one small sachet, around 1 tsp)

Add Everything to the Blender in Stages

Put all the fruit, oats, and peanut butter into the blender with just enough milk to let the blades work, around three to four tablespoons. 

Blend until you have a thick paste; you won’t have a smoothie yet, just a dense mixture that smells strongly of mango and peanut butter.

Now drizzle in the honey and add a small second pour of milk; blend again. 

When adding the honey at this stage, it will distribute through the whole mixture instead of sitting on top of a dense paste. 

Then pour in the rest of the milk and blend one final time until smooth.

The reason for blending in stages is to avoid adding too much milk early and ending up with a thin and watery smoothie. 

Also, when the peanut butter and oats break down into a paste first, they mix through the final drink much better than if everything goes in together from the start.

What Each Ingredient Is Doing

• Mango and banana are both the base, but they do different things. I used mango for the main flavor, and banana to make a smoothie thick and give it a smooth texture.
• So, without the banana, the smoothie will be much thinner and more juice-like, even with everything else the same.
• The avocado at 1.5 teaspoons is a small quantity (you won’t taste it as avocado), but it adds a roundness to the texture. 
• Oats are the filling element; they have fiber and the slow carbs that make this smoothie hold you through a workout. 
• Peanut butter adds protein and fat on top of that, so the two together give sustained energy that plain fruit smoothies don’t have. 
• Honey is doing less work than you might expect if your mango is already sour, which it was in my case.

What I’d Do Differently Next Time

The mangoes I used had less sugar and more acid than I expected.

I could taste the sourness from the first sip. But didn’t, thinking they’d be fine. 

Halfway through the glass, I added more honey and stirred it in, but it only improved the last few sips.

So I recommend you taste the mango before adding. If it’s sour, either find a ripe piece, use a smaller quantity, or add proper sugar from the start. 

Sugar dissolves well into the milk and spreads through everything; honey is good when the fruit is already sweet, but it won’t correct sourness the way sugar does.

You can also reduce the oats quantity. I should have done it, but I’ll do it next time, because this time I had more oats taste than other ingredients I used.

Try half a teaspoon next time.

Variations I recommend you try

A few things that would shift how this tastes:

• Cocoa powder: Add one teaspoon in the first blend alongside the peanut butter. It will lean into the chocolate peanut butter flavor and make the combination feel intentional.
• Dates instead of honey: Soak two or three dates for ten minutes and blend them in with the first stage. They will break down completely smooth and add a caramel sweetness that works better against a sour mango than honey does.
• Plain or almond butter instead of chocolate peanut butter: If you want the mango and banana to come through more cleanly, use plain peanut butter or almond butter. The fruit flavor is less competed with, and the smoothie tastes more fruity.
• More avocado: Going up from 1.5 teaspoons to two tablespoons will make the texture creamier and add more body. The avocado flavor becomes slightly detectable at that quantity, which is a different version of the smoothie but still a good one.

What to Have With This

If you’re having this drink before a workout, running, or any other physical activity, I’d recommend not eating much else with it. 

This is because it will already give you quite a lot of energy, and it will be sustained energy, meaning you won’t get a huge burst of energy all at once and then suddenly crash. 

It will keep you going for quite some time.

But if you want to have this after physical activity, if I were you, I’d eat boiled eggs with it. 

However, when I made it, I simply drank it. Apart from that, you can also try bread or an omelette.

If you’re making it during lunch, then also make yellow rice with potato; cold smoothies and drinks taste great with it.

Frequently Asked Questions

Does avocado work with mango in a smoothie?

It does, and the reason it works is that avocado doesn’t really taste like anything in this quantity; you won’t get avocado flavor with mango flavor. 

But you’ll get a creamier, thicker base that makes the mango taste richer instead of thin and juice-like.

My smoothie came out too sour, Did I do something wrong?

If your mango are sour, skip the honey and add a small amount of regular sugar instead. 

Sugar dissolves well in the milk and fixes the sweetness across the whole drink. 

Honey works when the mango is already sweet.

Can I add protein powder to this?

Yes, and it fits the drink well since you’re already using oats and peanut butter for sustained energy. 

Add one scoop with the first blend at the paste stage so it mixes in before you add milk.

If you use a flavored protein powder, go for vanilla or chocolate and pull back on the chocolate peanut butter so the drink doesn’t get too heavy on one flavor. 

Why chocolate peanut butter and not plain?

Mostly because that’s what I had at home; also, the chocolate peanut butter makes the whole drink feel more like a proper pre-workout drink.

If you use plain peanut butter, you’ll more easily taste mango and banana flavor, so both are okay.
