Caramel in any form is very sublime, but here it's combined with white chocolate to make a wonderful cake slice. My mother used to cook something similar when we were kids, and it always went down a treat.
For the Base
200g (7oz) butter shortbread biscuits
25g (1oz) butter, melted
For the Filling
150g (5oz) butter
150g (5oz) dark brown soft sugar
397g can Carnation Condensed Milk
For the Topping
250g (9oz) white chocolate, melted
You will also need a 20cm (8) square brownie tin lined with baking parchment
To make the base, process the biscuits until they are like crumbs, then stir in the melted butter. Spoon this mixture into the tin and, very lightly, press to make an even layer. Chill for 20 minutes.
Place the butter and sugar in a non-stick saucepan over a low heat, and stir until the butter melts and the sugar dissolves. Add the condensed milk and bring gently to the boil, stirring continuously, to make a golden caramel. As soon as it comes to the boil, remove from the heat and leave to cool slightly.
Spoon the caramel over the crumb base in an even layer. Pour the melted white chocolate over the caramel, spreading it out to the edges.
When the chocolate has hardened a little, but before it has set hard, cut into slices, and enjoy with a cup of coffee.
