caramel frosting:
melt 1.5 sticks unsalted butter in a pan. once the butter is melted, add 2 cups light brown sugar and .5 teaspoon salt. let sugar dissolve then take off heat and cool for a couple minutes before adding 1/2 cup of milk and 2 teaspoons vanilla extract. you must let this cool completely! then pour into mixer and add 4 cups of confectioners sugar and mix. (although the recipe calls for 4 cups confectioners sugar, start with 2 cups and add a little more until you get the right consistency.)
