Thanks ladies! Lulu that cake is all over Pinterest! She chose the theme too - unicorn rainbow!!! Made a rainbow bunting tonight and am making a little paper one for the cake as well - just need to get the icing right. I think my problem in the past has been not whipping the butter for long enough and it's gone all weird and soggy!!! Being winter and freezing here we have the heating on and it just oozed which I do not want happening on this one! Onyx that french cream one looks good too - not sure what to do now!

Does anyone have a cream cheese one that is reliable and white?!!
