  1. Heat the oven to 180°C / 355°F. Grease and line three 20 cm tins. Beat the butter and 300 g sugar until pale. Beat in the eggs one at a time, then the vanilla.

  2. Mix the flour, baking powder and salt. Fold into the butter mixture alternately with the milk until smooth. Divide the batter into six equal portions.

  3. Bake three layers at a time, in the tins, for 10 minutes each until pale gold. Cool on racks, then bake the remaining batter in the same way.

  4. For the frosting, boil the 400 g sugar, cocoa, butter and evaporated milk in a saucepan for 5 minutes, stirring. Take off the heat, stir in the vanilla and beat until smooth and spreadable.

  5. Stack the layers, spreading each with frosting while it is warm, and finish with the remaining frosting on top and around the sides. Leave to set.

Worth Knowing

  • Weigh the batter so that the layers come out the same thickness.
  • Keep the frosting warm and spread it fast; it thickens as it cools.
  • Cut the cake with a hot, wet knife for neat slices.

Why the Method Is What It Is

Count the layers. A Smith Island cake is made from many thin layers of yellow sponge, here six, each spread with a cooked fudge frosting that is poured on warm and soaks slightly into the cake. The result is tall and striped, and every forkful has more frosting than a conventional cake would give you.

The sponge is a basic butter cake, made in one bowl, and baked in thin layers. It does best in 20 cm tins, with 120 g of batter in each; weigh it to keep the layers even. The layers bake in 10 minutes and need no more than a light golden colour. Overbaking makes them dry and brittle.

Make the frosting while the layers cool and keep it warm. It is sugar, cocoa, butter and evaporated milk, boiled for a few minutes and beaten smooth. Spread it thinly between the layers while it is still pourable, then pile on the rest. It sets as it cools to a fudgy finish that holds the cake together.
