"You have to work out the volume properly, to acurately adjust the amount for different size tins. Assuming the recommended cake tin of 30cm dia is 4cm high, it's volume is approx 2800 cubic centimetres. A 17cm dia round tin of the same height, is approx 900cc, so the recipe amount would have to be reduced to approx one third. Think about it, as an example, a 6" square would fit 4 times into a 12" square tin, not twice. Dig out the calculator !! Volume of a round tin = height x pi (3.142) x radius squared."

"I made this for my husband's 40th birthday, as a practise for a 3 tier all chocolate wedding cake I'm making later in the year. I used an 8" square tin. I worked out the volume of the 12" recommended round tin size, (equivalent to 11" square) then scaled back the recipe proportionally. It's a pain but it's the most accurate way to adjust to different size tins. I also used creme fraiche instead of soured cream, as I can't get that where I live in France. For the 12" square wedding cake base I intend to make, I won't be bothering to increase the amount at all. "
