Put the avocados into a bowl. Combine with the lime juice and 2/3 cup of sweetened condensed milk.

Purée with an immersion blender (or with food processor or blender) until smooth and creamy.

Taste and see if it needs more sweetness. If so, add more sweetened condensed milk as needed and blend to ensure everything is incorporated.

Divide into 3 ramekins and refrigerate for 2-3 hours or until thoroughly chilled.

Just before serving, sprinkle the tops with sugar and brûlée using a blow torch (or broiler if you don’t have one).
