The one where you surround the shape with kitkats and fill the centre with smarties/m&ms? I have only seen that done as a round cake, but it got a "wow" from the assembled 6yos even then, so I would say a '7' shaped version would be a definite birthday-girl-pleaser.
When I was seven my mum made what I still think was the best cake ever - big square cake, with the seven dwarves from snow white lying in it like a big bed! So little heads and feet sticking out from under a big fondant blanket, with Twixes as the bodies under the blanket, and a sack of jewels and a pickaxe lying next to the bed. It was from the Jane Asher book I think!
Fondant on chocolate cake is fine, BTW - use a reasonably dense chocolate cake (G&B's inmates cake is my default). If she is really keen on chocolate you could get Belgian chocolate sugar paste to cover it?
Butterfly? Round chocolate sponge cut in half and pieces turned to face outwards, chocolate swiss roll as the body. Then you can decorate the wings with icing, smarties etc. I usually make a Victoria sponge and buy playmobil to suit the theme! Pirates, Olympics, beach, girl with rabbit...
Im pretty good at decorating cakes (if i do say so myself :p) and my Step Dad has asked me to make a cake for my Step sisters 7th Birthday. I have no clue what to make, he is pretty unambitious and said a cake in the shape of a seven would be fine. The only thing my sister has requested is that the cake be chocolate.
I have no idea what to make, Id like to make something really cool, but it only has to feed about 7 people so not too big. Also I dont know if fondant/royal icing stuff goes with chocolate cake on the inside? I always make a plain sponge usually.
Anyone made any cool cakes lately? My sister doesnt seem to have many interests as far as themes go, but she is not a pink girly girl.
