Golden syrup and custard slice

This no-bake slice is absolutely delicious, however it does require patience. It'll be about 6 or 7 hours before you can eat. But the wait is worth it.

Ingredients:
250g pkt Arnott’s Butternut Snap Cookie
1/4 teaspoon ground allspice
100g butter, melted
375g cream cheese, chopped, at room temperature
100g (1/2 cup) caster sugar
375ml (1 1/2 cups) thick custard
2 teaspoons gelatine powder

Golden Syrup Topping
125ml (1/2 cup) golden syrup
60g butter, chopped
60ml (1/4 cup) thickened cream
1 teaspoon gelatine powder

Putting it all together:

Grease a 16 x 26cm (base measurement) slice pan and line with baking paper, allowing the long sides to overhang.

Break up biscuits. Place into a food processor and process until resembles coarse crumbs. Add the allspice and butter and process until evenly combined. Transfer to the prepared pan and press evenly into the base. Place in the fridge to chill for 30 minutes or until required.

Place 2 tablespoons of water in a small microwave-safe bowl and sprinkle over the gelatine. Set aside for 2-3 minutes for gelatine to soften. Microwave on HIGH for 20 seconds or until hot. Use a fork to whisk the gelatine, to dissolve completely. Cool slightly.

Place the cream cheese and sugar in a food processor and process until smooth. Add the custard and process until combined. Use a rubber spatula to scrape down the side of bowl. Add the gelatine mixture and process until combined. Pour over the biscuit base and place in the fridge for 4 hours or until set.

To make the golden syrup topping, combine the golden syrup, butter and cream in a small saucepan over medium heat. Cook, stirring, until butter has melted and mixture is smooth. Transfer mixture to a jug. Place 1 tablespoon of water in a small microwave-safe bowl and sprinkle over the gelatine. Set aside for 2-3 minutes for gelatine to soften. Microwave on HIGH for 10 seconds or until hot. Use a fork to whisk the gelatine, to dissolve completely. Cool slightly. Gently stir the gelatine into the warm caramel sauce. Place mixture in the fridge for 1 hour, stirring occasionally, or until cooled and thickened slightly. Pour over the slice. Place in the fridge for 3 hours until set
