I've been asked to bake a cake for a friend's surprise 50th birthday party on Superbowl Sunday. While I already have the flavor combinations down, (I'll be making two cakes since she is a vanilla poundcake fan but everyone else seems to prefer chocolate), I'm not sure what to do about decorating the cake. (Though there'll be two cakes I'm planning on just having the chocolate cake look "nice" whereas the vanilla cake will really serve as her birthday cake. However, if anyone had any ideas for some sort of theme that would work on both cakes, that'd be great too.) Basically, this individual doesn't really have any strong hobbies or interests that I feel I could use in the decoration scheme, isn't into football meaning I can't play off of the Superbowl, and is simply out of my age range (I'm 25), meaning I don't really know what is appropriate for a 50 year old's cake. Any suggestions, specific or general, would be much appreciated. I should note that while I do a huge amount of baking and a fair amount of cake decorating, my decorating skills at times don't match my ambition, so I'd prefer decorating ideas that might take a lot of planning, but that don't necessarily involve intricate details requiring a overly steady hand which I don't have. Thanks in advance!
