Birthday cake assembly advice please.

[Posy1]

Can anyone advise me? I'm trying to assemble a princess cake for my daughter's 5th birthday (I'm not a baker unfortunately). I'm wondering can I put this cake (www.waitrose.com/ecom/products/waitrose-decorate-your-own-cake/603785-713661-713662) on this cake (www.waitrose.com/ecom/products/undecorated-chocolate-cake/483202-68215-68216 ) without any support or will it squash the bottom cake? I'm going to get an edible icing topper for the smaller cake and decorate around the side with princess figurines. Any advice is much appreciated. Thanks

Unfortunately I cannot see the top cake, says "sorry product no longer available", are you going to put plastic figures round the base? I'm no baker, but my my DGKs tell me what they are "into" , I make basic cake or sponge, take it from there,I do sometimes buy toppers on e bay. My DHS had a laser party, one year I had a soft icing topper made with his name and age.

DGS, that should read.

If it's going to be standing assembled for a few hours then you will need support to stop the top cake sinking, but support is easy.

If you have any plastic straws left then you can just poke 4 of those in under where the top cake will sit and snip them level so they don't poke out.

If you don't have plastic straws then a baking supply store will have the same thing labelled as cake supports for more money.

The link doesn't work for me either but I did a search on decorate your own cake and it's a 7" iced madeira sponge. I wouldn't put that on top of chocolate, madeira is a pretty dense sponge and it might even be heavier than the larger chocolate cake.

Decorate one cake and have this as The Cake for show and candles etc and then when you cut them up, cut up both cakes so people have choice (assume that's why you want both).
