Cut the puff pastry into four squares.

Place in a preheated oven at 375°F (190°C) until cooked and well browned, then arrange in a baking dish.

Drizzle the sweetened condensed milk in lines over the puff pastry and pour the hot milk over it until covered.

Whip the topping mix, cream, and vanilla with the cold milk.

Spread over the top, sprinkle with coconut and nuts for garnish, place in the oven for about 10 minutes, and lightly brown the top.
