This turned out clumpy,clear, and liquidy. I had to keep adding and adding then straining the confection sugar to make it more hard. I finally decided to add cocoa powder, and that fixed everything. It tastes a lot better now!
I thought this recipe was too sweet and that the flour made it too heavy. Also, there was not enough frosting to frost a 9x13 cake. I tried making it again, and doubled the butter, salt, & milk. I used a little less than 1/2 cup flour, 1/2 t. of vanilla, and only 3/4 cup of sugar. It turned out extremely fluffy and melted in our mouths. My husband loved it.
