4 c. packed brown sugar (light)
1 to 2 tsp. vanilla
1 c. half and half
1 c. melted butter

Mix all together; bring to boil over high heat. Boil 18 minutes on medium-low heat, stirring occasionally. Put pan in cold water and beat for about 5 to 7 minutes until it thickens. Pour into buttered plate or pan. Cut when cooled. If it hardens too soon, just add a little milk to smooth it out, then put in dish. Can also be used for icing on a jam cake.
