Sao Vanilla Slice

Sao Vanilla Slice

1/2 cup custard powder
1/2 cup caster sugar
3 cups milk
1 tsp vanilla essence
1 packet Arnott’s SAO Biscuits
1/2 cup of passionfruit pulp, fresh or canned
50g unsalted butter or margarine
3 cups icing sugar

Place custard powder and sugar in a saucepan and make into a smooth paste with a little of the milk. Gradually stir in the remaining milk. Stir continuously over gentle heat until custard comes to boil and thickens. Remove from heat and stir in vanilla essence.
Cover custard surface with cling wrap to prevent skin forming and allow to cool completely.
When custard is cool, spread a generous layer (1 – 1.5cm thickness) on a SAO biscuit and top with another biscuit to make a slice. Repeat this process until all biscuits have been used.
Combine passionfruit pulp, sugar and butter in a heatproof bowl, and mix over a pan of simmering water, stirring until the icing is smooth and glossy. Place in refrigerator for 5 minutes to thicken slightly.
Spread icing on top of each of the slices and place in refrigerator to set. Will keep up to 2 days in fridge. If you want to make the slice slightly sweeter, substitute SAO with Arnott’s Lattice biscuit.
