Yes, I know, she's slightly odd for not liking cake. Last year we layered loads of different flavours & sweets & sauces (all fruity,) into a large perspex bowl & put her candles on that, which she loved.
It's her 13th this year, so I was having a think - do you think it would work putting it into some kind of cake of jelly mould? The only drawback I could think of would be that you wouldn't see the icecream through the side, and you probably wouldn't be able to pop it out of the mould without defrosting it?
Or am I being dense and this is a really bad plan?
