Steps

Before you start

Use ripe avocados: the skin should be dark and the flesh should yield to gentle pressure. Underripe fruit makes a bitter, grainy shake.
Chill the milk and the serving glasses for 15 minutes if you can, so the shake stays cold and thick longer.
Wet or lightly oil your spoon before measuring condensed milk so it slides off easily.
Serve right away. Avocado browns and the shake thins as the ice melts.

1
Chill the glasses
- Place 2 tall glasses in the freezer or fridge while you prep.
- Measure the milk and keep it cold until needed.

Ready when: Glasses feel cool to the touch.
2
Prep the avocados
- Cut each avocado lengthwise around the pit and twist the halves apart.
- Remove the pit, then scoop the flesh out with a large spoon, scraping close to the skin to get the greenest flesh.
- You should have about 1 cup (230 g).
- Roughly chop it into chunks.

Ready when: Flesh is bright green and creamy with no brown or stringy patches.
Tip: Cut away any brown spots; they taste bitter and dull the color.
3
Load the blender
- Add the milk, 4 tablespoons condensed milk, and the lime juice (if using) to the blender first.
- Add the avocado chunks, then the ice on top.

Ready when: All ingredients are in the jar, ice on top.
Tip: Liquids first helps the blades catch the ice and avocado without stalling.
4
Blend until smooth
- Start on low for 10 seconds, then blend on high for 45–60 seconds.
- Stop and scrape down the sides once if needed.
- The shake should be thick, pale green, and completely smooth with no ice chips or avocado flecks.

Ready when: Thick like soft-serve, pale green, with no visible ice chunks or avocado lumps.
Tip: If the blender stalls, add 2 tablespoons more milk. If too thin, add 3–4 more ice cubes and blend 15 seconds.
5
Taste and adjust
- Taste the shake.
- If you want it sweeter, add 1 more tablespoon condensed milk and blend 10 seconds to combine.
+ Show details− Hide details
Ready when: Tastes lightly sweet and rich, with avocado still the main flavor.
6
Serve immediately
- Drizzle 1 teaspoon condensed milk around the inside of each chilled glass, if using.
- Pour in the shake, dividing evenly, and serve at once with wide straws or long spoons.

Ready when: Shake holds a soft mound at the top of the glass.
Tip: Serve within 10 minutes; it thickens and darkens as it sits.

Tips

Ripe fruit is the biggest factor: pick avocados that give slightly when pressed at the stem end.
Add the ice last so the blades don't dilute the shake before the avocado is smooth.
For a more street-style texture, use less ice (1 cup / 130 g) and serve with a spoon.
Blend in short bursts if your blender is small, so the motor doesn't overheat and warm the shake.

Storage & reheating

Best drunk immediately. Refrigerate leftovers in a sealed jar filled to the top for up to 4 hours; stir or re-blend before drinking. Freeze in an ice cube tray for up to 1 month, then re-blend with a splash of milk. Do not leave at room temperature for more than 30 minutes.

Substitutions

whole milk → unsweetened oat or soy milk. Makes a dairy-free shake; also use coconut condensed milk.
sweetened condensed milk → 3 tablespoons honey or sugar syrup. Less creamy; add an extra splash of milk for body.
ice cubes → 1 cup frozen avocado chunks. Gives a thicker, richer shake with less dilution; reduce milk slightly.
fresh lime juice → lemon juice. Same amount; keeps the color bright.
