Preheat oven to 135 degrees.   Whisk the cream, egg yolks, sugar, and vanilla extract together in a bowl.   Mix it all up until it gets nice and creamy.   Pour this mixture into ramekins (those little ceramic dishes).   Place the ramekins in a baking pan.   Fill the baking pan with hot water, about halfway up the sides of the ramekins. Place the pan with the ramekins in the oven for an hour or so.   Then check them every ten minutes. You'll know they're done when you can stick a knife in one and it comes out clean.   Remove the ramekins from the baking pan, set them on the counter, and let them cool.

Then put them in the refrigerator and let them chill overnight.

Sprinkle a thin layer of the light brown sugar on the top of each. Make sure it's a THIN layer, but also make sure it completely covers the custard. Now torch it! Done - Enjoy!
