In a saucepan, place the eggs, the sugar and the vanilla essence. With a whisk, mix very well until combined. Once you've mixed, gradually add the milk, mixing constantly and finally, add the corn starch, mix well.
Bring to a boil over low heat and stir nonstop until a very consistent cream is formed.
Turn off the heat and add the cream cheese, mix well until combined.
Pour the cream into the cake mold, spreading it well over the biscuits and set aside.
In to saucepan, add the cocoa powder and the sugar, mix well and add the milk, mix again.
