Rinse the mung beans thoroughly and soak them for 2 hours until they expand. Drain and place them in a pot with water just above the beans. Cook until the beans are tender and the water has evaporated.

Remove from heat and mash the beans (or use a blender), then add the sugar.

Return to the stove and stir until the sugar dissolves. Let the dessert simmer for a few more minutes, then turn off the heat and add the vanilla extract, stirring once more.

Spoon the dessert into bowls. This sweet dish is suitable for special occasions.
