  8. Let it cool down for 5 minutes and then take it out on a plate.
  9. Serve the cake with vanilla ice cream or chocolate sauce.


  1. Milk should be at room temperature.
  2. To avoid lamps try to stir all the ingredients in one direction.
  3. Don’t play much with the batter after adding lemon juice (nimbu ka raas).
  4. Don’t fill the batter till the brim otherwise the cake may overflow from the dish.
  5. Power setting for each microwave differs so cook cake as per your own judgment. If after 5 minutes, cake is not cooked, allow it to cook for another 1 or 2 minute in microwave.

  5. Place it in fridge for 10-15 minutes. Now cut it in your desired shape.


  1. To avoid lamps sieve coco powder and milk powder before use.
  2. To check for one string consistency of sugar syrup – allow the sugar to dissolve in water. Continue to cook the syrup on low flame. When you touch the syrup between your forefinger and thumb, a thin string will form and it should not break. If it breaks, the syrup should simmer for a little while longer.
  3. You can add crushed nuts of your choice
  4. You can add 1/2 tsp of vanilla essence at the time of adding butter. Alternately, 2 tsp of strong coffee mixture can be added.’
  5. You can use ice tray as your mold and can get chocolate in the shape of ice cubes.
