In a heavy-bottomed saucepan, combine 700 ml of milk with custard powder slurry made by mixing custard powder with 50 ml of milk. Bring the mixture to a boil, then remove it from the heat.
Whisk in the condensed milk, then allow the mixture to cool down to room temperature.
Meanwhile, whip the whipping cream using an electric mixer till stiff peaks.
Once the custard mixture has cooled to room temperature, gently fold in the whipped cream and set it aside.
To make cocoa syrup, combine sugar and cocoa powder in a bowl, then pour hot water over the mixture. Stir until well combined.
For the Parle-G crumble, crush the biscuits, ensuring they remain chunky. Add melted butter and powdered brown sugar, then mix thoroughly. Bake the mixture at 160°C for 10 minutes.
For the assembly- Take a 6*6 inches square dish. Dip the parle-g biscuit in cocoa syrup for few seconds and then lay them on the serving dish.
Pour the custard pudding on top of the biscuit layer.
Repeat the process once more, then cover the pudding with a crumble made from Parle-G biscuits. Finish it off by garnishing with a Parle-G biscuit dipped in chocolate.
