Amazing Caramel Sauce

Recipe yields 1 1/2 cups

1 cup packed brown sugar (light brown or golden)
1/2 cup heavy cream
4 tablespoons butter
Pinch of sea salt
1 tablespoon vanilla extract

Melt butter in pot, mix in brown sugar, cream and salt. 
Cook over medium-low heat and whisk gently 
for about 7 minutes or longer if you doubled.
Remove the pot from the heat, add vanilla and return to 
cook for another minute or so to thicken a bit more.
Take it off the stove and pour into a jar then pop it into the 
fridge and VOILA you're done!
