For children’s tiramisu, line a shallow baking dish with the biscuits. Stir 3 tablespoons of cocoa powder into 200 ml of milk and soak the biscuits in it.
Whisk the curd cheese with the cream cheese and the sugar and pour over the biscuits. If necessary, add more layers of sponge cake and curd cheese mixture.
Soak each layer of biscuits again with cocoa. Finish with curd cheese mixture. Finally, sprinkle with cocoa powder. Let stand in refrigerator for at least 10 hours.
