Quite an odd one about cakes...

You won't be able to stack fruitcake and cheese on top of sponge, it's just too heavy. It will work as cheese, then fruit, then sponge though. We had 2 cakes, one sponge, one cheese, and the cheese (4 tiers) was so heavy it took 2 blokes to lift!

I too was going to say you cant put heavier things on the sponge. If you used a tiered cake stand (see pic), you could have any layer on any level as the weight of the cake/cheese is supported by the stand.

Are you having the sponge & fruit layers iced, then just having the wax of the cheese on show? Or are you going to try icing the cheese wax to look like the rest of the cake?

You can get polystyrene in the shape of a cake. This can be iced to look like the rest of the cakes. (I did this as a 3 tiered cake was too big for the amount of guests). You could have the cheese in the kitchen & it could still be served with the cakes.

Where in the country are you? Smithfield meat market in London have whole, waxed cheese wheels in one of the delis there. No ideas of prices though but they are cheaper than other places I've found for bries & other cheese. Have you looked at neals cheese yard (which sells online) or borough market, London?

I think this is a great idea but just bare in mind the weight issue that others have mentioned.

For cheese

Neal's yard https://www.nealsyarddairy.co.uk/

or cheese shed https://www.thecheeseshed.com/

Love the idea!

Again so long as it is stacked right you will be fine.

I'm also from Yorkshire - how about this place?

If they can't help with the cheese you particularly want, I'm sure they will be able to let you know where you could get it from.

I would be a bit worried that the cheesy flavour would leach into the other cakes if it's touching them ?
