Giant pizza cookies

Preheat oven to 180°C/350°F. Grease 3 oven trays and line with baking paper.

Beat butter, sugar and vanilla in a small bowl with an electric mixer until smooth and pale. Add egg and beat to combine. Stir in sifted flour and custard powder until a soft dough forms. Shape dough into a disc, wrap in plastic wrap and refrigerate 1 hour.

Divide dough into 3 equal portions. Using a rolling pin, roll out one portion at a time between sheets of baking paper until 20cm (8-inches) round. Place rounds on oven trays. Cut rounds into 8 wedges each (but don't separate the wedges). Bake for approximately 20 minutes or until crispy.

Spread jam over 'pizzas' leaving a 1cm (½-inch) border. To make 'salami', use the pastry cutter (3cm (1¼-inch) to cut rounds from the sour straps. To make pineapple pieces, cut musk sticks widthways into 3mm (¹/8-inch) slices. To make olives, cut spearmint leaves and Chicos widthways into thin slices.

Place 2 slices of 'salami' on each pizza cookie and scatter with 'pineapple' and 'olives'.

Melt white chocolate. Spoon into a small ziptop bag, snip end and drizzle chocolate over pizza to resemble melted cheese. Stand at room temperature until set.
