I have some leftover frosting which I made 2 days ago, and the directions said that it should be good for a few days, stored at room temp. I'm not ready to bake again - would it be okay to refrigerate the frosting, and whip it up after it returns to room temp? The ingredients were 2 sticks butter, 1/2 c milk, about 20 oz powdered sugar. Thanks!
(Oh, and $10 off your order of $50 or more in the Food52 Shop, too.)
