Hi Linsey,
I hope you can help, we love Delia's Christmas cake in the Christmas book and have cooked years for birthdays and Christmas, BUT I am celebrating my 60th birthday in august and am having a party for 150 so a big cake is called for.
Can you please tell how to scale up to a 13 inch square cake please
thank you
Jules
Hello Jules,
I suggest, but have not tested, a 14 egg quantity for your 13 inch square tin.
Give it extra layers of protection around the outside and make sure the top is covered with a double layer of parchment (not touching the cake mix).
If you are using a fan oven, we advise that you should reduce the given temperature by 20 degrees.
However as the classic Christmas cake is bake on a lower shelf I would reduce it to 115 degrees.
I would check the cake at 5 ½ hours then every 15 – 30 minutes after that depending on how it’s looking.
Best wishes
Lindsey
