In a mixing bowl, combine mango pulp and condensed milk. Stir until smooth and evenly mixed.
Add milk powder gradually, mixing continuously to avoid lumps and form a thick, creamy mixture.
Add desiccated coconut and cardamom powder. Mix until a soft dough forms that holds shape.
Cover and refrigerate the mixture for 20 to 30 minutes to firm up.
Scoop small portions and roll into bite-sized balls using your hands.
Roll each ball in desiccated coconut, pressing lightly so the coating sticks well.
Place the truffles on a tray and refrigerate again for 15 to 20 minutes before serving.
