Throw back to my first successful chocolate sponge/chiffon cake in 2010 (original post here). My family and I loved it so much that I made this cake a couple more times following - as seen here and here. Somehow somewhere this recipe got a bit forgotten in the past 7 years or so.
For my dad's birthday this year, I decided to dig up this oldie to see if it's as good as remembered. I made some slight modifications and encountered a bit of a mishap.
