I made this frosting the other night and frosted a single layer of round cake for my grandson who is allergic to dairy. I put peaks on it, sprinkled it with colored sugar and topped it with candy bug decorations that come in a set at the grocery store. It was lovely. I covered it with a bowl to protect it and left it on the counter overnight. By morning it was a disaster. Most of the frosting had softened and slumped down the sides. The top and sides still had a thin layer but most of it had pooled around the base of the cake. I thought maybe I should have refrigerated it. So I scooped the frosting back on top, swirled it around, and put it in the fridge for about four hours. Alas, the same thing happened. I took it to the party anyway, and it still tasted great. My daughter joked that it looked like it was from a Disney movie about climate change. Anyone have any suggestions about what I did wrong?
