When I was a child growing up my mum always made our birthday cakes. She’s extremely creative and they were really elaborate affairs. There were trains, tractors, princesses, umbrellas, monsters… my brother even had one based on the band U2. I am nowhere near as skilled or patient as my mum is but I really wanted to make Little O’s birthday cake. With some help from Pinterest and a recipe from my mum that I adapted, I think I pulled off something passable that pretty much anyone with a couple of hours of spare time could manage. The sponge cake method used here is an oldie but a goodie and makes a really light fluffy cake.
