Ingredients
Shortbread
- 225g plain flour
- 175g unsalted butter, cold, cut into cubes
- 75g caster sugar
Topping
- 150g butter
- 1 x 379g can condensed milk
- 100g golden syrup
- 350g dark chocolate, or a mixture of dark and milk, chopped into small pieces
Method
- Preheat the oven to 150C/300F/Gas 2. Line a 23cm/9in square cake tin with baking parchment.
- Combine the flour and butter cubes in a food processor and pulse until the mixture resembles fine breadcrumbs. (Alternatively, you can rub the butter in by hand.)
- Add in the caster sugar and pulse again until combined.
- Tip the mixture into the lined cake tin and spread it out evenly with the back of a spoon. Then press the shortbread down firmly with your knuckles so that it is tightly packed in the tin.
- Bake the shortbread for 30 minutes or until very light golden brown. Set aside to cool.
- Meanwhile, for the topping, heat the butter, condensed milk and golden syrup in a saucepan, stirring occasionally until the butter is melted and the mixture is smooth.
- Increase the heat and bring the mixture to the boil, stirring frequently. The caramel will thicken and turn golden-brown. Set aside to cool slightly, then pour over the cooled shortbread. Allow to cool completely.
- Melt the chocolate in a bowl set over a pan of simmering water (ensure that the bottom of the bowl does not touch the water), stirring occasionally.
- Pour the melted chocolate over the caramel and set aside until the chocolate has cooled completely.
- Cut into squares and serve.
