Millionaire's shortbread

Buttery shortbread, a thick layer of soft caramel and a snap of chocolate on top. The Scottish teatime traybake that never lasts long in the tin.

Ingredients

Method

  1. Heat the oven to 180°C (160°C fan) and line a 20cm square tin. Rub the butter into the flour and sugar until it clumps, press firmly into the tin, prick and bake until pale golden.
  2. Leave the shortbread to cool in the tin.
  3. Melt the butter, sugar, syrup and condensed milk in a heavy pan over a low heat, then bring to a gentle boil, stirring all the time, until it thickens and turns a deeper fudge colour. Don't stop stirring or it will catch.
  4. Stir in the salt, pour over the shortbread and leave to set.
  5. Melt the chocolate and spread it over the caramel. Chill until set.
  6. Lift out and cut into 16 squares with a hot, dry knife.
