A glass of Vietnamese avocado smoothie tastes like a rich milkshake, thanks to ripe avocado and sweetened condensed milk.
This creamy drink is so delicious that it might become your new favourite way to enjoy avocados. With only 4 ingredients, you can whip it up in just 5 minutes.

An avocado smoothie might sound unusual if you're used to thinking of avocados as a strictly savoury ingredient, but this creamy, sweet treat is about to blow your mind.
When I first heard about sinh to bo from my mom's co-worker, I was skeptical. But then she mentioned the secret ingredient: sweetened condensed milk.
As someone who believes that condensed milk is a pantry staple (I eat it on toast!), I knew I had to try it. Now, it's on permanent rotation at my house.

Why This Recipe Works
- It has just a few steps
- The ingredients are easy to find
- You can easily make it dairy-free
- You can adjust the sweetness to your preference
"This is literally the best milkshake I’ve ever had! It is sweet, creamy and delicious. Thank you so much!" - Kristina
Don't let the word "smoothie" fool you - this Vietnamese avocado drink is much more like an avocado shake than the smoothies you might be used to.
In Vietnam, an avocado smoothie is enjoyed as a sweet treat or light dessert, not as a healthy breakfast drink.
It's thick enough that you could eat it with a spoon, or drink it through a wide straw, and it can be sweet enough to satisfy your dessert cravings (depending on how much sweetener you add).
Think of it as the Vietnamese cousin of a classic diner shake - only naturally green and buttery.
The cool, custardy texture is refreshing on a hot summer day (and that's when I tend to crave this recipe).
Ingredients and Substitutions

- Ice cubes: Chill and thicken the smoothie. Substitute with frozen avocado slices for an even better texture and flavour.
- Ripe avocado: Choose a ripe Hass avocado, or a similar variety, for the creamiest texture. Store-bought frozen avocado chunks may work if fresh avocados are hard to find.
- Sweetened condensed milk: Adds richness and sweetness. Condensed coconut milk is a great dairy-free alternative. Otherwise, try agave syrup or honey. Maple syrup also works but drastically changes the flavour.
- Whole milk: Keeps the drink silky. Feel free to replace with low-fat milk, or use coconut milk, almond milk or oat milk for a dairy-free version.
Variations
- Breakfast Avocado Smoothie: Replace the condensed milk with 1 or 2 teaspoons of honey, and about ½ cup of low-fat vanilla Greek yogurt (makes 2-3 portions).
- Tropical Twist: Avocado and coconut are a delicious combination! Substitute dairy milk for coconut milk, and the condensed milk with condensed coconut milk. Garnish with coconut flakes.
- Caffeinated: add a shot of cold espresso into the drink and stir.
- Chocolately: drizzle the finished drink with chocolate syrup (the kind used on ice cream)
How to Make a Vietnamese Avocado Smoothie

Step 1: Add ice and avocado into a blender jug.

Step 2: Add the milk.

Step 3: Add 2 tablespoons of condensed milk. You can add more later.

Step 4: Blend on high speed. If your blender has an ice-crushing mode, start with that and then switch to a high speed.
Once the mixture is blended, taste it. If it's not sweet enough for you, add more condensed milk (1 tablespoon at a time) until you reach your desired sweetness.
Enjoy this drink cold or at room temperature.

Tips for Success
- For an even thicker avocado shake, use frozen avocado pieces.
- A high-speed blender will give you the best texture.
- Sweeten the drink with just a couple of tablespoons of condensed milk, then slowly add more until you reach your preferred sweetness.
- If the smoothie is too thick, add milk, one tablespoon at a time, until you reach your desired texture.
- If the smoothie is too thin, add more avocado, one piece at a time, and check the consistency.
- Serve immediately in tall glasses with a wide straw or spoon for the best texture. Be cautious when using a metal spoon in a glass, as it can easily break. I prefer using a wooden spoon instead.

Freeze ripe avocados that you can't use up and save them for making this drink - it's a great way to reduce food waste.
Frequently Asked Questions
Yes, you can use condensed coconut milk, agave or honey to taste.
Yes! Mash very ripe avocados with a fork, then stir in the other ingredients. You won't get a super smooth texture but it will still taste great. If you don't have a regular blender, but do have an immersion blender, you could try that as an alternative.
This avocado shake is best served fresh, but it can be stored in the refrigerator for about 12 hours. After a while, the drink may start to discolour. If the ingredients have separated while in the fridge, give the mixture a good stir before drinking it.

Try to add 1/2-1 really ripe banana, and use soy-vanilla milk. Then you do not add the condensed milk.
Really good!
Shareba says
That sounds like a nice, healthy alternative. Thanks for sharing Dora!
Drago says
+1 for the banana. My banana wasn't very sweet so I added honey instead of condensed milk. It was really yummy! The avo makes it so creamy!
The problem with bananas is smoothies is that they sort of stain it. You can't get rid of the taste, NOT that it tastes bad.
Shareba says
Yeah the avocado gives it a really nice creaminess, which I love! I know what you mean about the bananas overpowering the taste though.

Love, love, love the Vietnamese Avocado Shake (Sinh to bo) recipe! The first recipe is perfect. Thank you for sharing.
Chloe says
When I went to Vietnam to visit my family there, one of the smoothies tasted almost exactly like this recipe! It's good to know that some people still honor the local people of Vietnam's recipe!
Shareba Abdul says
Thanks Chloe!

I first had avocado smoothies in Thailand. Had some amazing flavor combinations with fresh local fruit, but I can't remember what they were 🙁
I like coconut milk in smoothies instead of milk.
Here's one that I made: blackberry, mint, avocado

Interesting, I thought only brazilians used to consume avocado this way. The main way we used to consume avocado is in a simple smoothie made with avocado, milk and suggar, some people use to put lemon skin, mint leaves or condensed milk too. Thank you for the information!
Shareba Abdul says
Lemon would be really interesting in there, I'll have to try that!
Paul says
I love the last one it's super tasty. Thanks for sharing.
T says
The one I had at a little v. Place was milk condensed milk, honey, or raw sugar.
Coconut milk is a good substitute milk. Of course the avacado. It was soo good.
Shareba says
I'm glad you liked it 🙂
Sarah says
I've heard of this being done before, but could never find a good recipe. I might experiment with using almond milk too. Thanks!
Christina C. says
