Step 1

Preheat oven to 180C/160C fan forced. Brush a 4.5cm-deep, 1.5L (6 cup) baking dish with a little melted butter.

Step 2

Place 1 pastry sheet on a clean work surface. Cover the remaining sheets with a clean, dry tea towel and then a damp tea towel. Brush the pastry with a little melted butter. From 1 short end, drag the pastry until it forms an accordion-like strip about 2cm wide. Place around edge of prepared dish. Repeat with the remaining pastry sheets, working towards the centre and scrunching slightly to fit as necessary, until the base of the dish is covered. Place the dish on a baking tray. Bake for 20 minutes or until golden and crisp. Remove from the oven.

Step 3

Whisk the sweetened condensed milk, milk eggs and vanilla in a jug until combined. Carefully pour mixture all over the pastry. Bake for 20 minutes or until set. Set aside for 10 minutes to cool slightly. Serve warm dusted with icing sugar.
