Looking for Children's Cake Recipe

Hello Lindsey
I have searched everywhere for Delia's recipe "Children's cake" but to no avail. It was a traybake sponge which I made often when my children were small. They are now grown but I wanted to make it again recently. I have all her books but alas cannot find it in those either. Can you help me please or suggest a similar sponge recipe which could be adapted. I liked this recipe in particular because the texture and amount of batter were perfect for my requirements. Thank you for any advice or guidance you can give me.
