Chill your tools. Place your loaf pan or freezer-safe container in the freezer. If using an ice cream maker, chill the bowl according to the manufacturer’s instructions.
Prep the avocados. Slice, pit, and scoop the flesh into a blender or food processor. Make sure they’re ripe and green inside.
Blend the base. Add coconut milk or heavy cream, sweetener, vanilla, citrus juice, and salt.
Blend until completely smooth and airy, about 45–60 seconds. Taste and adjust sweetness.
Churn option. If using an ice cream maker, pour in the mixture and churn until thick and soft-serve consistency, 15–25 minutes. Stir in any mix-ins at the end.
No-churn option. Pour the blended mixture into the chilled pan.
If you want extra lightness, whip the heavy cream separately to soft peaks and fold it into the avocado blend before freezing. Cover tightly.
Freeze. Freeze 3–4 hours for scoopable texture. For firmer ice cream, freeze longer; let it sit at room temp 8–10 minutes before scooping.
Serve. Scoop with a warm spoon or scoop.
Finish with a sprinkle of sea salt, shaved dark chocolate, or a few berries if your carbs allow.
