Lemon Victoria Sponge with Vanilla Buttercream & Lemon Curd

The first cake I ever ate was a Victoria sponge. I remember a giant slice being presented to me at the table. The slice 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 remember the jam splodges left on the plate, and being so overcome with excitement at the flavour that I picked it up and started licking it. Safe to say this didn’t go down so well with my mother!
