Boil milk and sugar together until sugar melts. Add cocoa powder and stir thoroughly till it's all combined well. Make cornflour slurry in water at room temperature. Add it in the sauce
Stir until the sauce boils and thickens (the sauce will be thick enough to stick to the spoon. Remove from flame and cool it down thoroughly. It will thicken further as it cools. We are looking for thick pouring consistancy like batakavada batter.
Combine 1 cup water and 3 tsp coffee. Boil till coffee melts. Let it cool completely.
To whip cream, chill the bowl and the cream in freezer for 2 hours maximum. Take out the cream in the bowl and whip. Start with low speed gradually increasing as it thickens. Whip till it's slightly looser than stiff, but a bit thicker than soft. If you try to drop it from spoon, it should drop in the shape of a ball when you give a slight jerk. Add the chocolate sauce and cocoa powder and gently fold in to combine evenly.
To assemble the pudding, grease the tray with ghee/butter. Take a biscuit at a time and wet it a bit in the coffee water. Place it in the tray. Make a layer of biscuit likewise. Pour toffee sauce over it and spread it evenly. Then spread whipped cream. Repeat layers in the same order.
Sift some coffee powder over the top most layer of cream. I made a patter with spoon to give it some texture. Let it set for at least 2 hours in the refrigerator. In fact it tastes batter if you set it overnight. That way, the biscuits soaks up the coffee and chocolate flavours very well and they also puff a bit in size giving a batter taste.
Tips: 1. Do not soak biscuits in coffee for too long or else they will get very soggy and will also taste bitter. 2. Whipping cream till the right consistency is very important. Soft cream will melt soon and will not hold the pudding well. Very stiff cream like for cake frosting will not spread well on pudding and will not blend well with the biscuits. 3.I prefer to use the whipping cream given in the pic below. It has never let me down. 4. Keep the layer of biscuits thicker than cream.
