This was my first try at covering a double barrel cake in fondant... Let's just say it didn't go too well. By this morning Olaf was on the table, the cake was seriously leaning almost to the point of falling over, and the cake was about 1 1/2" shorter than is was last night! Oh well - I just straighten the cake up, put a dowel down the middle, slapped some butter cream frosting around the bottom and stuck some extra fondant under Olaf. My friend's daughter loved it!
