Boil milk in a non-stick
pan, add castor sugar and mix till the sugar dissolves. Mix custard powder with some cold milk in a small bowl till no lumps remain. Add this mixture to the boiling milk and mix well, and cook on medium heat till the mixture thickens. Take the pan off the heat, transfer into a mixing bowl and let the custard cool down to room temperature.
Heat 2 tbsps water in
a small non-stick pan, add coffee powder and mix well to make a concoction.
Take hung yogurt in
another bowl, add whipped cream and mix well. Add this mixture to the custard mixture and mix well. Put this mixture into piping bag and chill in the refrigerator.
Place a cake slice at
the base of a serving bowl. Soak it with some coffee decoction. Pipe the chilled custard mixture over it till the bowl is half filled. Repeat these layers till all the cake slices and custard are used up.
Keep the bowl in the
refrigerator to chill.
Dust some cocoa
powder on top just before serving.
