Mix together the cream, sugar, and vanilla in a microwavable bowl. Then heat for 2 minutes in the microwave. Remove and set aside.
Beat the egg yolks in a medium bowl until smooth. Stir the yolks into the cream mixture.
Divide the custard mixture evenly between four 6-ounce ramekins. Place the ramekins in a 9x13 baking pan.
Heat some water in a saucepan, not quite to the boiling point. Then pour the hot water into the baking dish until it comes halfway up the sides of the ramekins creating a water bath.
Bake for 1 hour and 35 minutes. Start checking the custard at about the 1 hour and 10-minute mark. If they need to cook longer, continue to check every 10 minutes. You'll know they're done when you can stick a knife in one, and it comes out clean.
Carefully remove the ramekins from the baking pan. Set them on the counter, and let them cool for 15 minutes. Then transfer the ramekins to the fridge to chill overnight (at least 8 hours).
The next day, sprinkle a thin layer of sugar on top of each custard. Make sure it's a THIN layer that completely covers the custard.
Use a kitchen torch to brûlée the entire top of the dessert until the sugar caramelizes into a hard layer sheet on top of the custard. (see note)
Serve immediately, garnished with fresh raspberries and some mint if desired.
Notes
If you don't have a torch, you can put them under the broiler for a minute or so, just keep an eye on the sugar so it doesn't burn.
If you want a thicker sugar crust, you can add another thin layer of sugar and brûlée it again. Just know that the edges may start to burn more than caramelize.
