Hi there,

I was hoping that someone could help me.

I have to bake a leaving cake for a friend that is leaving the country on Friday, and I want to use my normal sponge recipe which is:

4oz (110g) butter
4oz (110g) caster sugar
2 large eggs
4oz (110g) self-raising flour
Which I bake at gas mark 3, (for those that don’t use a gas oven325F, 170C) for around about 20 - 30 minutes.

Generally I bake by eye and edit that mixture to suit what kind of cake I’m making which to date has never failed me yet. The problem I’ve got is that I’m making a bigger cake this time and using a 10inch spring-form round tin rather that my normal 7-8inch round tin. And for the life of me I just can’t work out how to scale up my ingredients, and I’m assuming the baking time will go up as well.

If someone could help me out with this i would be forever grateful to them

Kara:

There was a thread on this just a week or so ago:

But I’ll repost what I posted there.  You simply need to figure out how the pan volume of your 10 inch relates to the 8 inch pan.  You can use this table, assuming a 3 inch high pan:

``` Diameter   Height   Radius    Volume    Factor8          3          4       150.8       17          3        3.5      115.45       0.778          3          4       150.8       110         3          5      235.62       1.56  ```

The factor you need is in the last column.  To move from an 8 inch pan to a 10 inch pan, you’d need to multiply your ingredients by 1.56.  In other words, you need a little over 50% more stuff.
