This Vietnamese avocado smoothie, known as sinh tố bơ, is a creamy drink that also works as a spoonable dessert. Avocado provides the body, while milk, sweetened condensed milk, and ice create a cool, gently sweet blend. The key is balancing the liquid and ice so the smoothie stays rich without becoming difficult to blend.
This avocado smoothie recipe is a proposed home version, not a claim of a historically authentic formula. It makes two servings and starts with a modest amount of sweetener, leaving room to adjust for your avocados and your preferred sweetness.
Recipe Overview
- Yield: 2 servings
- Preparation time: About 10 minutes, including cutting, measuring, blending, and adjusting

Ingredients
Use these quantities as a starting point. Avocados vary in size and texture, so the final splash of milk is best added after checking the first blend.
- 2 medium ripe avocados, enough for approximately 1 1/2 cups of flesh
- 1/2 cup cold whole milk, plus 1–4 tablespoons more as needed
- 3 tablespoons sweetened condensed milk, plus up to 1 tablespoon more to taste
- 1 cup ice cubes, preferably small cubes or crushed ice
Choosing the Avocados
Look for avocados that yield slightly to gentle pressure. Very firm flesh can be difficult to blend smooth, while fruit with a sour smell or extensive dark, mushy areas should not be used. Cut each avocado open before adding it to the blender so you can check the flesh.
Milk and Sweetener
Whole milk is the starting choice here for a creamy result, but a different milk can be used. Sweetened condensed milk contributes both sweetness and body; it is not interchangeable with unsweetened evaporated milk without changing the result. Begin with the listed amount, then taste before adding more.
How to Make the Avocado Smoothie
- Prepare the avocados. Wash the avocados, cut them lengthwise around the pits, and separate the halves. Carefully remove the pits and scoop the flesh into a measuring cup or bowl. Aim for approximately 1 1/2 cups. Cutting and measuring should take about 4 minutes.
- Load the blender. Add 1/2 cup cold milk and 3 tablespoons sweetened condensed milk to the blender, followed by the avocado flesh and 1 cup ice. Putting the liquid in first can help the blades move the mixture. Allow about 1 minute for measuring and loading.
- Blend until smooth. Start on low, then increase the speed as the ingredients begin moving. Blend for about 30–60 seconds, or until no visible avocado pieces remain. If the mixture stops circulating, turn the blender off before scraping down the sides. Never put a utensil into a running blender.
- Adjust the consistency and sweetness. Check the texture. If it is too thick, add extra milk 1 tablespoon at a time, using up to 4 tablespoons, and blend briefly after each addition. Taste and add up to 1 tablespoon more condensed milk if desired. Blending, checking, and adjusting should take about 3 minutes altogether.
- Serve immediately. Divide between two glasses or small dessert bowls. Use a spoon for a thick smoothie or a wide straw for a thinner one. Allow about 2 minutes for portioning and serving.
Tips for a Smooth, Creamy Blend
Add Liquid Gradually
It is easier to thin a thick smoothie than to rescue a watery one. Start with the measured milk rather than pouring in enough to cover the avocado. If your blender struggles, stop it and add a small splash of milk before restarting.
Keep the Ice Manageable
Small cubes or crushed ice are easier for many blenders to process than large, solid cubes. Follow your blender manufacturer’s guidance on crushing ice. If the motor sounds strained or the blades are not moving the ingredients, stop rather than letting it continue.
Taste After Blending
Do not judge sweetness from the condensed milk alone. Taste the fully blended smoothie so you can assess the avocado, milk, and ice together. Add more condensed milk in small amounts; a little adjustment can change the balance noticeably.
Make Only What You Plan to Serve
The texture is best suited to immediate serving. As the ice melts, the smoothie becomes thinner, and the surface may darken during storage. Preparing the glasses and measuring the ingredients before cutting the avocados helps keep the process moving.
Serving Suggestions
Serve sinh tố bơ in short glasses for a drink or in small bowls for a dessert-style presentation. There is no need for a topping: the plain blend keeps the focus on the avocado and makes it easy to judge the texture.
For a spoonable serving, stay close to the starting quantity of milk. For a smoothie that flows more easily through a wide straw, use the extra milk gradually. Avoid adding a large handful of ice at the end, which changes both the texture and the balance of sweetness.
Suitable Variations
- Less sweet: Start with 2 tablespoons of sweetened condensed milk instead of 3. Blend and taste before deciding whether to add more.
- Dairy-free adaptation: Replace the whole milk with an unsweetened plant-based milk and use sweetened condensed coconut milk in place of dairy condensed milk. Check product labels if avoiding dairy. The flavor and thickness will differ from the base recipe.
- Light vanilla flavor: Add 1/4 teaspoon vanilla extract with the milk. Keep the amount small so it does not overwhelm the avocado.
- Smaller batch: Halve every starting ingredient to make one serving. Use a small blender jar if available so the blades can catch the mixture.
Frequently Asked Questions
Can I make this without sweetened condensed milk?
Yes, but the result will have a different sweetness and body. For a proposed alternative, replace the 3 tablespoons of condensed milk with 2 tablespoons of additional milk and 1–2 teaspoons of sugar. Blend thoroughly, then taste and adjust.
Why is my avocado smoothie too thick?
The amount of avocado flesh, size of the ice cubes, and blender performance can all affect consistency. Stop the blender and add milk 1 tablespoon at a time. Restart briefly after each addition until the mixture circulates and reaches your preferred thickness.
Can I use frozen avocado?
Plain frozen avocado pieces can work, though the smoothie may need more liquid. Measure approximately 1 1/2 cups, start with 1/2 cup ice instead of 1 cup, and add more ice only after checking the blend. Follow any preparation directions on the package.
Can I prepare it ahead?
Immediate serving gives the most predictable texture. If you need to hold it briefly, cover it and refrigerate it promptly. Stir before serving and expect some thinning or surface darkening. For easier advance preparation, measure the milk and condensed milk ahead and leave cutting and blending until serving time.
