Ingredients

250g pkt Arnott's SAO biscuits
90g cornflour
50g custard powder
1 cup caster sugar
3 cups milk
300ml thickened cream
60g butter, chopped
1 tsp vanilla bean paste
3 egg yolks, lightly beaten
1 1/2 cups icing sugar
2 tbsp passionfruit pulp
15g butter, softened

Preparation

Step 1

Grease a 20cm x 30cm slice tin, line base and sides with baking paper, extending the paper 5cm over the edges.

Step 2

Biscuit base: Place half the SAO biscuits on base of tin, trimming as necessary to neatly fit.

Step 3

Custard filling: combine cornflour, custard powder and sugar in a medium saucepan. Gradually stir in milk and cream, whisking until smooth. Stir continuously over medium-low heat until custard comes to the boil.

Step 4

Reduce heat and simmer, stirring, for 3 minutes until mixture is thick and smooth. Whisk in the butter. Remove from heat. Gently whisk in vanilla and egg yolks until smooth.

Step 5

Spread filling evenly over SAO biscuits. Top with remaining biscuits, trimming as necessary to fit. Cover and refrigerate for at least 3 hours or until set.

Step 6

Passionfuit icing: Combine icing sugar, pulp and butter in a heatproof bowl, stirring over a pan of simmering water, until the icing is smooth and glossy. Pour icing evenly over SAO biscuits. Refrigerate for 20 minutes until set.

Step 7

Cut into squares before serving.
