This cake was for my 4yo son's birthday. He is a big spiderman fan. 4 8x8 layers. Walls are rice krispy treats molded and cut to size. Accents are fondant and buttercream. I had so much fun with this cake. However, when I pulled the RKT off to cut the cake all of the icing came off with it. Any advice on that?? A big THANK YOU to all of you fellow cc'ers for your inspirational cakes and wonderful tips!
