Va-va-voom chocolate biscuit cake
When I was a child, every birthday party had a chocolate biscuit cake, and I loved it. When I became an adult, I realised that it wasn’t compulsory to stick to digestive biscuits! So I bought loads of chocolate bars, experimented with many different combinations - all in the name of science, of course - and came to this version. As well as tasting great, it looks dramatic and beautiful.
