Cake timing question

[truelymadlysleepy]

I've made this before but made a right mess of cutting it into three.
Have decided to try again but in x2 20cm sandwich tins. What do you think about timings?
Am paranoid about opening the oven too early due to previous experiences of pancake cakes

Truly just made 2 cakes in 2 8 inch tins 1 lemon and 1 coffee and walnut, both 28,30 mins gas 4 or 160 fan 180 ordinary.

Thanks nanny, this is very dense one. I cooked at at 140' for 60 mins and it was fine. Just waiting for it to cool now for the ganache.

Glad its fine, they have to be two of my favourite things,Mmm.
