In a medium bowl mix Condensed milk, whole milk, eggs, and vanilla.

Mix well with a whisk. You could also use a blender. Set aside

Pour your sugar into a saucepan and take it to simmer over low heat to make Caramel. It will start melting. Some crumbs will form but evenctually it will get liquid. Wait for it to be completely melted and get a beautiful amber color. Remove from heat.

Immediately pour your caramel in your cookie can, and start spreading the caramel all over. Be careful since it's really, really hot.

Next, pour your milk mixture in the cookie can. Cover it with the lid.

Cook it on bain-marie (double boiler) over medium heat for about 45 min. Use a big pot and put your cookie can inside, add in water to the big pot until it gets 1/4 of the can (not the pot). Cover the pot with its lid too.

Past the 45 minutes, remove from heat and let it cool untill warm but not cool. You should be able to hold it with your hands and still feel it warm.

Once it's warm, replace the can lid with a dish or cake stand and turn it over to unmold it.

Serve and enjoy!
