I'm trying to use this for only the second time. It takes a whole Victoria sponge mix which should take 25 minutes at 180oC when divided into 2 sandwich tins. Because I was baking it as one I dropped the temp to 170 to try and stop it burning before it was cooked. It took almost an hour to be done in the middle but is overdone round the outside.
Any tips? I am cooking in a electric fan oven and had it on the bottom shelf as its quite a deep tin.
My other question is that all my sponges including cupcakes rise unevenly with a big peak in the middle when when smooth in the tin when it goes in the oven. How do I get the nice slightly risen finish of a proper victories sponge?
