Mix coffee and 250 ml milk. Take 4-5 tablespoons off and stir with caramel pudding powder until smooth. Season to taste with sweetener. Put the rest of the latte in a pot. Remove 4-5 tablespoons of the remaining milk and stir with the cream pudding powder until smooth. Stir in some sweetener. Put the remaining milk in a pot as well.
Bring the coffee latte to the boil, stir in the caramel pudding powder and simmer for about 1 minute while stirring. Bring the rest of the milk to the boil, stir in the cream pudding powder, bring to the boil again and simmer for about 1 minute while stirring. Rinse 6 small moulds with cold water and put the different puddings in them immediately. Put them in a cool place for about 6 hours. Then carefully remove the puddings from the rim of the moulds with a knife. Turn out the puddings from the ramekins and serve decorated with orange slices, lemon balm and mocha bean as desired.
