Her recipe:
1 stick butter, 1 cup brown sugar, 1/4 teaspoon salt. Cook 2 minutes. Add 1/4 cup milk. Cook, stirring until it boils. Add 2 1/2 cups sifted powdered sugar and 1/2 teaspoon vanilla.
So you beat it or just mix in the powdered sugar? This sounds good and I might try it with the cooks illustrated yellow cake. My kids wouldn’t like it but I think I would love it with a layer of crushed peanuts like a snickers cake.
