Heat the milk in a saucepan until little bubbles form around the edges and add the oats. Cook gently for about 5 minutes, stirring often, until the oatmeal is thickened.
Stir in the cinnamon and vanilla and spoon into two serving bowls.
Smooth out the top of each bowl with the back of a spoon for form a flat surface for the sugar.
Evenly sprinkle 2 teaspoons of sugar over each bowl
Use a kitchen torch to caramelize the sugar, moving the flame in circles as the sugar turns color. Keep heating until the entire surface is browned and you start to see small black spots.
Serve hot with a dash of cream.
Notes
You can try doing this under the broiler if you don't have a torch. It works, but it's tricky, and you have to have the bowls up close to the flame. You also have to make sure your bowls are broiler safe. (The torch works better!)
