Prepare a cup of strong coffee and allow it to cool.
Separate the eggs into whites and yolks. Heat the whole milk with Bonny Sweetened Condensed Milk in a pan for 5 minutes. Add the whipped egg yolks and thicken the mixture by heating gently (do not boil) for 20-25 minutes.
Add the thickened mixture to a baking dish with tall sides, and place it in a refrigerator for one hour. Mix Bonny Cream with vanilla sugar, and add these to cream cheese.
Soak the lady finger biscuits in the cold coffee and place these on the cooled mixture of milk and egg yolks until all the biscuits are used.
Then, spread the cream mixture over this and sprinkle cocoa powder on top. Place the dessert in a refrigerator for at least 2 hours.
