First, place the milk in a saucepan and add the sugar, cornstarch, and vanilla extract. Mix well using a whisk or a spoon until fully combined.

Then, bring it to medium heat and cook, stirring constantly to prevent burning, until the mixture thickens and becomes smooth.

Next, transfer the cream to a bowl, cover it with plastic wrap (touching the surface of the cream), and let it cool completely.

After that, in a mixer, beat the whipped cream until it forms firm and stable peaks.

Soon after, pour the cooled cream into the bowl with the whipped cream and beat for a few more minutes, just until the mixture is smooth and well blended.

Assembling the dessert:

First, quickly dip the cookies into milk.

Then, line the bottom of a glass dish with the soaked cookies and spread a layer of cream on top.

After that, repeat the process, alternating layers of cookies and cream, until all ingredients are used. Make sure the final layer is cream.

Lastly, sprinkle grated chocolate (using the side of the grater with thicker holes) over the top.

To finish, place the dish in the refrigerator and chill for a few hours, until the dessert is cold and set.

The final result is a creamy and delicious dessert made with simple, everyday ingredients.
