I've read several times now that cat's can't taste 'sweet' because they don't have the appropriate taste buds.
However, one of ours seems to love sweet things - whenever we have cakes, biscuits etc she will be rubbing up against us or sniffing round hoping to find some crumbs she can eat. We're always careful to keep anything with Chocolate or raisins away from her as we know they're bad, but is there any problem with a few crumbs?
If it's not the sugar, is there something else in cakes and biscuits/cookies that she's attracted to?
