I've been working on two cakes today. Used the same buttercream to ice both. One cake is hazelnut vanilla cake, and it was fine. The cake is finished and beautiful. The other cake is red velvet. I'm piping a big swirling design on this cake with the buttercream and it's just falling off! Can't be the icing because it worked beautifully on the other cake. What is going on?!?! Cake is due tomorrow, and I'm catering a graduation dinner tomorrow night. So, I can't work on it tomorrow - have to finish this tonight. Please help if you have any tricks I can try.

Is it too hot in the kitchen? Maybe put it in the fridge for 15 min or so? I really don't k ow if that will help but good luck!

The fridge will help. Sometimes the heat from your hands thins it out-I had that disaster on Mothers Day. If you are icing the side that would've been the bottom, sometimes the non-stick spray can affect its ability to stick (had this happen too ) Good luck with your cake!!

Thank you. It is hot and extremely humid today. I've put it in the fridge and am praying it helps. Won't take it out until delivery tomorrow. I'll have to have an extra big decoratin kit with me when I deliver!
