Dear Lindsay,
I'm making a 3 tier wedding cake using Delia's rich fruit cake. The tins I'm using are round and the following dimensions: 15cm x 7cm, 23cm x 8cm and 30.5cm x 9cm. I'd like each tier to be the full size of each tin but I'm really struggling to get accurate scaling (I've tried at least 5 times) but keep ending up with different results each time as I'm not sure how deep the original recipe starts out at!
Please can you help!
Many thanks
Tilly

Hello Tilly,
It sounds like you’ve done quite a lot of work on this already.
What amounts of mixture (i.e. the number if eggs) did you try in the tins you have and what are / were the height if the baked cakes?
Kind regards
Lindsey
Hello Lindsay,
The 5 attempts were on the calculations, rather than making the cakes!
The trouble I'm having is that I don't know how deep the cake is in the receipe here: https://www.deliaonline.com/information-centre/scaling-up-cake-recipes so I've got no starting point
Thanks
Tilly
Hello Tilly,
As you are so specific about the heights you want, and I do not have enough test results to guarantee a specific height I’m hesitant about responding to your question!
Bear in mind that a rich fruit cake, when cold can be trimmed down quite easily.
Our 8 inch / 20cm cake made with 4 large eggs is about 3 inches / 7.6cm high.
My best guess for the heights you’re aiming for is this…
30.5 by 9 = 14 large egg mix
23 by 8 = 5 large egg mix
15 by 7 = 3 large egg mix
However, I cannot guarantee the heights, so you may prefer to increase these amounts (and possible need to trim) in order to get exactly what you want. Or go with what I suggest and if any fall short you could do a thicker layer of marzipan and icing!
Kind regards
Lindsey
