Hi all,
Really hope someone on here can help me - I have been volunteered to help with a friends wedding cake hmm and have a recipe for a 7in tin but need to make a 10in and 12in cake. Is there an easy way to adapt the quantities?

The 7in recipe is:
6oz butter
6oz caster sugar
6oz SR Flour
3 large eggs
1 tsp baking powder

Many thanks in advance!!!

Ok, time for some maths..... <goes off to get calculator>

Assuming your 7in tin is about 1 inch deep, and your 10 and 12in tins are 3in deep -

the cakes you need to make are (very roughly) 15 times the volume of the 7 inch cake. So.....

90oz butter
90oz caster sugar
90oz SR flour
45(!) large eggs
90 tsp of baking powder (or 30 tablespoons).

I'd follow the same instructions and then divide between the tins as you see fit. NB I have rounded up so you may have slightly more than you need. If your tin depths are different let me know and I'll recalculate as that'll make a big difference
