Hi everyone. I'm really at the end of my tether with this one so any advice would be really helpful. I baked a very simple victoria sponge yesterday with my kids. We followed the recipe completely. When the timer sounded I looked into the oven it had risen beautifully and was a lovely brown colour. Took it out, pierced it with a skewer and it came out clean. Left it to cool in the tin, looked 5 mins later and it was flat as a pancake. Cut into it later and it just looked solid & uncooked, and tasted horrible. Same happened last week with an easy bake chocolate cake recipe we tried - both from BBC recipes website. Help please, what am I doing so very wrong???
