I have a cake due this evening and I can't get the bulging to go away!! It is a 2 tiered with a sugar cookie in the middle. I leveled the cakes last night, put the sugar cookie in the middle, put a crumb coat on it, and placed in the fridge all night. This morning I put the icing on and it is bulging so bad!! I scraped off the icing and reapplied the icing, but i STILL can't get the bulging to go away...PLEASE give me some advice!TIA!
