Directions

1. Heat the brown sugar and butter in a small pot on medium-high heat. Stir slowly until the mixture turns a dark brown.
   
2. Slowly add the milk and stir until it’s completely mixed in. Be careful it will sputter. Don’t worry if the brown sugar and butter seems to solidify; just keep stirring the mixture over medium-high heat and it will all melt and mix together.
   
3. Once the milk is mixed in, and there are no solid bits add the vanilla extract and cinnamon and stir to incorporate.
   
4. Then turn off the heat, ladle it into a mug, add another sprinkle of cinnamon on top, and serve immediately.
