For the pastry brittle: roll the pastry out thinly and cut into circles. Spread one circle with melted butter and dust with icing sugar. Place a second pastry circle on top and again spread with melted butter and dust with icing sugar. Place on a baking sheet.
Repeat until 8 finished pastry circles have been created.
Bake the pastry circles at 170 °C for approx. 10 minutes.
Cut circles out of the advocaat and orange parfait. Place a circle of advocaat parfait onto one pastry brittle and place another sheet on top. Add a circle of orange parfait on top and follow with another sheet of pastry brittle. Finish with another advocaat parfait.
Tip: Decorate with chopped pistachios and raspberries.
