Preheat your oven to 350°F (175°C). Gather all your ingredients so everything is ready to go.
Whisk the cream and 3 tablespoons of sugar in a microwave-safe bowl until combined. Heat for 1–2 minutes until warm, then whisk again to fully dissolve the sugar. Add the egg yolks and vanilla, whisking until smooth and silky.
Set two ramekins inside a roasting pan and pour the cream mixture evenly into them. Carefully pour hot water into the pan until it reaches halfway up the sides of the ramekins.
Bake for about 50 minutes, or until the custard is set but still slightly wobbly in the center. Remove the ramekins from the water bath and refrigerate for at least 2 hours, or until completely chilled.
Sprinkle 1 tablespoon of sugar over each chilled custard. Use a kitchen torch to melt and caramelize the sugar until it bubbles and turns golden. Let the topping harden, then serve and enjoy the satisfying crack.
