In a saucepan, add heavy cream and heat it on medium heat until it just starts to simmer. Make sure you don't burn it.

Remove the heavy cream from heat and add vanilla extract. Mix well.

Slowly pour the heavy cream into the egg yolk and sugar mixture. Whisk vigorously for 2 to 3 minutes.

Pour this custard mixture into two ramekins.

Place the ramekins in a tub filled with enough water to be half-submerged in it. Place the whole setup in a preheated oven at 325 degrees F for about 30 minutes or until the edges are set and the centers are a little soft.

.Once done, take them out of the oven and let them cool down.

Sprinkle sugar on top and melt it using a grill torch until it turns a golden color and forms a layer.

Serve!
