- 175 g (6oz) plain flour
- 50 g (2oz) rice flour
- 75 g (3oz) caster sugar
- 200 g (7oz) salted butter, chilled and cut into cubes
- 350 g (12oz) dark chocolate, chopped
- Gold leaf, optional
For the caramel
- 175 g (6oz) salted butter
- 175 g (6oz) caster sugar
- 100 g (3 1/2oz) golden syrup
- 1 x 397 g tin condensed milk
- 1 tsp. vanilla extract
- Step 1
Preheat oven to 180°C (160°C fan) mark 4. Line a 20.5cm (8in) square tin with parchment. In a food processor, whiz both flours and sugar with 175g (6oz) butter until mixture comes together into large clumps. Press into the prepared tin and level as best you can. Prick base all over with a fork and chill for 15min.
- Step 2
Bake for 18-20min until lightly golden; leave to cool in tin.
- Step 3
Meanwhile, put all caramel ingredients except vanilla into a pan; whisk over a low heat to dissolve sugar. Bring to boil, then simmer for 10min, whisking constantly, until it turns a caramel colour. Stir in vanilla, then pour the caramel over the shortbread. Leave to set at room temperature for 1hr.
- Step 4
Melt chocolate and remaining 25g (1oz) butter in a heatproof bowl set over a pan of gently simmering water. Pour chocolate mixture over caramel; leave to set for 2hr in fridge or until solid. Press gold leaf, if using, on to surface. Cut into squares; serve.
