Mix the pudding powder with 6 tablespoons of sugar and stir with a little cold milk until smooth. Heat the rest of the milk, stir in the mixed pudding powder and bring to the boil. Let the finished pudding cool down.
Line a loaf pan (26 cm long) with aluminum foil or cling film. Layer the pudding and biscuits in layers, like with the cold dog. Put in the fridge for about 2-3 hours until everything has cooled down nicely.
The pudding can also be cooked in the microwave. To do this, stir the pudding powder / sugar mixture into the milk with the whisk and bring to the boil at full power. Stir in between.
