I am fairly new to cake making and I am doing my first wedding cake. It is a vanilla sponge, buttercream and jam filling. I have coated each layer in Gnash and Icing and it looked lovely.Over night the bottom layer had slid forward, middle to the side and all layers have bulged, it is now a very wonky cake and looks terrible! I don't have time to re-do the icing because the wedding it TOMORROW!Is there anything I can to do without having to re-ice the whole thing?Thank...
