Best Darn Caramel Icing

So this icing recipe has nothing healthy about it, but it is the most delicious caramel icing you will ever put in your mouth. It is a recipe passed down from my mom to me, so now I get to share with you! Pair this icing with your favorite boxed yellow cake mix or I like to use Real Simple's homemade yellow cake recipe.( http://www.realsimple.com/food-recipes/browse-all-recipes/yellow-cake )

It is fairly simple and this recipe makes a great amount for a layered cake, 24 cupcakes or a sheet cake. 

Here are the ingredients:

-1 stick of unsalted butter 

-1 cup of brown sugar (light or dark)

-1/4 teaspoon of salt

-1/4 cup of milk 

-1 bag of powdered sugar (1 lb.) 

-1 teaspoon of vanilla 

 Instructions:

1. Stir the butter, brown sugar, salt, and milk on the stove top in a medium sized pot until it is all melted and comes to a slight boil. 

2. Remove pot from the stove and add the powdered sugar and vanilla and stir until it becomes smooth. 

IMPORTANT- This icing gets hard really quickly so once you have made it, you must ice your cake or cupcakes ASAP. So, have your cupcakes and cakes cooled before you even make the icing.
