Custard Layer Cake...

You wil need the following:
Classic sponge cake: (Makes 1 cake)

• 4 large eggs 
• 300 ml (250 g) castor sugar
• 500 ml (2 cups) flour
• 15 ml (3 T) baking powder 
• 250 ml (1 cup) full cream milk
• 100 g butter
• 5 ml (1 t) vanilla essence

Custard filling:

• 6 egg yolks
• 180 g (¾ cup) castor sugar
• 70 ml corn flour
• 500 ml (2 cups) milk
• 5 ml vanilla essence

Method:

1. Preheat oven to 180ºC.
2. Beat eggs and castor sugar together until thick and creamy. Sift the flour and baking powder together and fold into egg and sugar mixture.
3. Heat milk and butter, but do not boil. Add vanilla essence and stir into batter.
4. Spoon into 2 x 20 cm greased cake pans. Bake for 25-30 minutes and remove from oven.
5. Whilst the cake layers are still hot, use a cotton thread and “cut” horizontally in halve. Place on a wire rack to cool.
6. In the meantime, make the custard filling: Beat the egg yolks and castor sugar together until light and foamy. Sift the corn flour and fold into the egg mixture.
7. Heat the milk until just below boiling and add, in a thin stream, to the egg mixture whilst beating constantly.
8. Heat over medium heat until the mixture thickens. Stir constantly.
9. Remove from heat and beat in the vanilla essence. Leave to cool.
10. To assemble the cake: Divide custard into 4 portions and use as filling and topping for each cake layer.
11. Sprinkle with ground caramel, if desired.

Hint:  The cake should be kept in the fridge if not eaten on the day that it was baked.
