Please help me with this cake, I don't know what to do. It is for a party Saturday. Here is the cake:

The werewolf head and arms is RKT with buttercream on it. The cake is bulging very badly in the back, below the head.

I have removed the head, if I can fix the rest of the cake I can replace the head right before the party. Is there any way to get the cake back to a somewhat presentable appearance? I don't have time to rebake anything, but I have some time tomorrow after work to do some fixes. It is all sitting in the fridge at the moment. One of the arms also slid off the sides, but I used several toothpics and bamboo skewers, and that seems to be holding it. 

Something similar happened to me. My cake sat at room temperature and got too soft. What filling did you use? The head must have put extra weight on it in the back.You don't have to re bake it.  You could take the arms off and scrape it all down if you have time to make more icing. Maybe put wax or parchment paper on top  of the whole cake and something  to weigh it down evenly in case their are more air pockets inside like a flat plate or a piece of tile. Let that stay on it while it's in the fridge until tomorrow. 

Then crumb coat, put it back in the fridge for a bit, re ice, add the arms, put it back in the fridge and you can wait to put the head on right before the party. Or if you cant make more icing, you could let it firm up and try to patch up the bulge, re smooth it and let it stay in the fridge in a covered box or container until the party.

So sorry this happened to you, hth.

Did you put some sort of support under the head to stop the weight of the head pushing down and causing the bulging?

i think you have used jam or jelly as a filling that's what hapened to me when i use jelly or jam as a filling .The layer of cakes will be slippery because of jam and jelly my suggestion is if you want to use jam or jelly just spread thin layer of jam or jelly and you SMBC or butter cream as a filling

Yep. When I made a solid icing lighthouse for the corner of a square cake, I positioned it on top of a cake pop stick in case it had any ideas! Support, smooth over, refrigerate and you'll be fine :) 

Hi everyone, thanks so much for replying. So, I had to scrap the first cake. I saved the head (thank god, since that's where most of the labor was) Sent the cake to my dad's work and his coworkers were happy to demolish it. My mom was kind enough to step in and re-bake the rounds, and the party is today, not yesterday, so that gave me another day!

For the first cake, I did not have support under the head. I had skewers holding the head onto the cake to prevent it from shifting, but nothing for support. And I did use jelly filling (actually one half was jelly and one half bavarian cream). This time I just did a thin layer of buttercream. I also let the cake settle for a few hours while weighted. I've got the head back on, with skewers underneath a cake board cut to size to support it. Plus some long skewers to hopefully keep the head on during the drive. I've also got the RKT arms on, and am just waiting for the candy melt coating on them to dry so I can finish up the frosting. So far, no sign of bulging! I also put the arms fully on top of the cake, so they won't slid off the sides. The cake is from the 2014 Wilton yearbook, and the arms on their cake are definitely on the sides. I assume they are using some form of dark magic to keep them there. Anyway, better go, I leave for the party in an hour. I will post pictures when it's finished!

Bummer sorry you had to scrap it but it went to a great cause, at least someone got to enjoy it, lol. Thank goodness for your mom chipping in and your being able to save the head.

So much for fairy dust, black magic and unicorn sneezes, we in the real world learn by our mistakes and this one will only make you better in the future. Sounds like the second go round should be okay. Cant wait to see pics.

Good luck and best wishes!
