Flora's Celestial Carmel Sauce

Thanks to my wonderful sister, Flora S., who is a celestial sister and a celestial cook!  This Carmel Sauce will send you over the top!  From the kitchen of Laurel Udall... Drizzle over vanilla bean ice cream and bananas! Picture from twosisterstherecipes.blogspot.com.~Mom

Carmel Sauce
2 2/3 cup brown sugar
1/2 cup butter
1 cup heavy cream
In the top of a double boiler, over direct heat, melt butter.  Then put the top of the double boiler over very hot water and add brown sugar and cream.  Stir well to incorporate the butter into the other ingredients.  Cook mixture over simmering water for 11/2 hours.  The sauce does NOT come to a boil.  Stir once in a while.  The sauce will thicken as it cools.  Use right away (before is gets sugary).  If you are completely out of ice cream or bananas, just lick it with your spoon (I can eat this by the spoonfuls)!
