In preparation for Hurricane Ike I made my cake on Friday for my monday class assuming we would loose power over the weekend. Well we did and luckily my cake was baked and iced before we did. We still do not have power and the colored butter cream icing has little white spots in it. Is this mold already growing or what is this? Today we had 70-85 degree temps inside the house... is it safe to continue to leave my cake out in a glass cake holder?
