It was very nice, thanks for your help.
Can you freeze normal sized/mini muffins?

yeah, one gas mark lower

and it's meant to be sticky!

I meant to add -
when I keep my cakes in a container they always go sticky.
Would it last wrapped in foil?

Thank you.
I could do ordinary sponge too but I thought I'd spice it up a bit.
I've got gas is that just 1 mark lower?

cooking time will be longer and 20ºC cooler

will probably be ok till sun but make sure it;s in an airtight tin else it'll dry out.

personally I am lazy and would do a Victoria sponge because I can make one in my sleep

I'm making a cake for tea for my son's 5th birthday on sunday.
I've chosen to use an apple muffin recipe (my Grandma can't eat chocolate ) and make it as one big cake, for something different, I wondered if the cooking time would be the same? or longer?
Also if I make it today, will it last 'til Sun?
Any other recipe suggestions welcome.
Thanks again (in anticipation) for your help and advice.
