Custard Slice is my Mum’s favourite thing to buy at the bakery. So, I popped around to her place after work and snuck some of this into her fridge for her (and Dad, and my ‘should really be moving out of home soon’ brother) to find once she got home. I found it surprisingly easy to make at home, it looks fiddly and complicated, but trust me, it’s not. The custard slice is delicious and is just as good as a store bought one (if not better because it was made at home with love – cheesy much?!)
2 sheets frozen butter puff pastry, partially thawed
1 ⅓ cup caster sugar
1 cup cornflour
¾ cup vanilla custard powder
4 ½ cups milk
75g butter, chopped
2 egg yolks, lightly beaten
1 teaspoon vanilla essence
2 ½ cup icing sugar
½ cup passionfruit pulp or sauce
Preheat the oven to 200˚C. Grease and line a 6 cm deep, 20 cm cake tin, extending the paper 3cm above the edges of the pan.
Line two baking trays with baking paper. Place 1 sheet of pastry on each tray. Bake one tray at a time for 8 – 10 minutes or until golden and puffed. Carefully flatten the pastry (using an oven mitt is a good idea – it’s hot!). Set aside to cool.
Place the sugar, cornflour, custard powder and 1 cup of milk, in a heavy-based sauce pan over a medium heat. Gradually stir in the rest of the milk until smooth and combined. Add the butter. Cook, stirring constantly for 8 to 10 minutes or until the mixture simmers and thickens. Remove from the heat and stir in the egg yolks and vanilla.
Trim the pastry sheets to fit the baking tin. Place one pastry sheet in the bottom of the tin. Pour the hot custard over the pastry. Top with the remaining pastry sheet. Set aside for 30 minutes top cool.
To make the passionfruit icing, place the sugar, butter and passionfruit in a heat proof bowl over a pot of simmering water. Stir over the heat until smooth and combined. Refrigerate for four hours or until cold. Cut into squares before serving.
