This is a recipe from Mary Berry’s Baking Bible. It’s a traybake which always work so well when you have a crowd or when you have to transport your bakes as they can be left in the tin till ready to serve.
You get the lightest, just like pieces of lemony clouds once you follow the steps. It’s a very simple recipe which has never failed to go down really well. The topping originally is a lemon flavoured icing but if you prefer, make up a drizzle with caster sugar, heated with a little water to which you add the zest of a lemon and spoon over the top of the still warm sponge. Deelish!
