Preparation :
In a saucepan, mix the sweetened condensed milk, cream and powdered milk.
Turn off the heat and mix well until the mixture is smooth.
Then turn the heat on to medium temperature and stir until the cream thickens.
Transfer the cream to a refrigerator-safe dish, cover
with plastic wrap that comes in contact with the surface, and let cool to
room temperature or refrigerate to speed up the process.
