In a microwave-safe baking pan, add mango puree, desiccated coconut, sugar, milk powder, and cardamom powder. Mix everything and place the pan in a microwave for about 5 minutes.  After 5 minutes, take out the pan, stir the mixture and place the pan in the microwave again for another 5 minutes. Keep microwaving the burfi in 2 minutes intervals until the mixture is thickened. Remove the pan from the microwave and flatten the burfi using a silicon spatula. Garnish with the dry fruits or silver foil and let the burfi set. When it is almost set, cut into squares and serve.
