Ingredients

Sponge Cake

  • 4 eggs
  • 1 cup caster sugar
  • 1 cup plain flour (preferably cake flour)
  • 1 teaspoon cornflour
  • 1 tablespoon butter
  • 4 tablespoons boiling water
  • 1 teaspoon cream of tartar
  • 1/2 teaspoon bicarb soda

Condensed Milk Filling

  • 1 tin condensed milk
  • 2 lemons

Instructions

Sponge Cake

  • Separate egg whites from yolks.
  • Whisk whites using a hand beater on low-medium speed until stiff.
  • Add egg yolks and continue beating for another five minutes.
  • Add sugar gradually to egg mixture while continuing to beat on low-medium speed.
  • Sift flour, cream of tartar and cornflour three times.
  • Fold dry ingredients through egg and sugar mixture using a spatula.
  • Combine melted butter, boiling water and bicarb soda. Once combined, add to mixture and combine well using a spatula.
  • Pour mixture into a lined round cake tin and bake in a moderately slow oven for 50 mins.
  • Once cake is cooked, allow to cool for two minutes before turning out onto a cooling tray covered with two clean tea towels.

Condensed Milk Filling

  • To make condensed milk filling, pour condensed milk into a bowl.
  • Juice the two lemons and add the lemon juice to the condensed milk.
  • Whisk by hand until mixture is an even, thick consistency.

Notes

To assemble, allow cake to cool completely.
Spread mock cream (I used Nan Mac's recipe) around sides of the cake and spread a thin layer on the top of the cake.
Using a piping bag and star nozzle, pipe stars around the outside of the top of the cake.
