Why did my cake go a bit soggy?

[goldilocks]

Made an orange and yoghurt sponge cake today from the Sainsburys mag that dropped on the mat last week.

Followed the instructions to the letter, but am a bit disappointed as the base was a bit heavy and soggy :-(. Still tastes fab :thumb:, but not the nice light sponge I was hoping for :no:. Think it'll be good with custard as a pud for the kids though so it wont go to waste :happyno:

Any ideas what went wrong?

Did you take it out of the tin to cool?

I left it for 10 mins in the tin ( as directed on recipe) then cooled on a wire rack
