James Martin’s millionaire’s shortbread
For the biscuit base:
- 300g salted butter, softened
- 200g dark soft brown sugar
- 350g plain flour
- 125g cornflour
For the caramel filling:
- 1 x 397g jar dulce de leche
- 250g salted butter
- 150g caster sugar
For the topping:
- 400g dark chocolate (70% cocoa solids), broken into pieces
- 100g salted butter
- Preheat the oven to 170C (150C fan)/325F/gas 3. To make the biscuit base, put the butter, sugar and both types of flour into a large bowl.
- Use your fingertips to rub the butter into the other ingredients until the mixture looks really crumbly.
- Press the mixture into a 23 x 30cm loose-bottomed cake tin (no need to line) and use a palette knife to even out the surface.
- Bake for 20 minutes, then remove from the oven and cool in the tin on a wire rack.
- To make the caramel filling, combine the dulce de leche, butter and sugar in a large saucepan over a medium heat. Whisking the mixture, bring to the boil (be careful as the mixture will be extremely hot).
- Pour evenly over the biscuit base, cover and leave to set for at least four hours or overnight at room temperature.
- To make the topping, put the chocolate and butter into a medium heavy-based pan and gently heat. Once everything has melted, whisk to combine.
- Cool slightly, then pour over the caramel and level with a palette knife.
- Cover, then leave to set overnight at room temperature.
- Cut into 12 squares to serve.
