Does anybody have any advice on the attached?
Using a new oven and set temperature to 180 degrees for a fan oven and cooked for 20 minutes. Have never seen such a weird lot of cakes. Any suggestions as to what has happened?

At a guess, the temperature given was for a conventional oven.
I'd drop that down to 160C and use low fan speed setting if available.
