This is an easy recipe for yummy results but will take some time to set! Millionaires Shortbread is made of three layers; shortbread, caramel and chocolate.
To make the Millionaires Shortbread follow the method for the 'Christmas Shortbread' recipe for the base omiting the spices. But cook the shortbread in a square tin (20cm by 20cm) and cool in the tin.
To make the caramel put 100g butter or margarine, 100g light muscovado and 397g condensed milk in a pan and heat gently until the sugar has dissolved.Cool slightly. Pour this over the cooled shortbread base (in the tin still), spreading evenly and refrigerate.
Meanwhile melt 200g chocolate in a pan over simmering water (taking care that the bowl doesn't hit the water) and pour over the top of the caramel layer. Refrigerate for a couple of hours, until the caramel and chocolate has set.
When it is set take it out of the tin and cut into squares.
Serve and enjoy!
