Lemon Victoria sponge with vanilla buttercream & lemon curd

The first cake I ever ate was a Victoria sponge. I was presented with a giant slice at the table. It was at eye level and I remember doorstop layers of red, white and pale yellow. The only way to eat it was to knock it over and pull it apart. I was so overcome with excitement at the flavour that I picked up the plate and started licking the jam splodges left on it. Safe to say this didn’t go down so well with my mother!
