Marbled Millionaires Shortbreads

Difficulty – Moderate

These marbled millionaires shortbreads have a light crisp shortbread base, a vanilla flavoured caramel and are topped with milk and white chocolate. It’s a moderate bake as the caramel can be a little tricky for a beginner baker, but as long as you continuously stir it and don’t overheat it you should end up with a lovely caramel. It’s a lovely bake for an afternoon snack, for a gift or for children’s party.

Gluten free plain flour – Plain gluten free flour does not normally contain xanthan gum. For this recipe you do not need to add any xanthan gum as the shortbread needs to be crisp and crumbly. As gluten free plain flour does not contain xanthan gum or gluten it produces a delicious light crisp and crumbly shortbread.

Chocolate – For this recipe I have used a good quality Swiss white and milk chocolate. The better the quality the chocolate you use the better the flavour.

Tip: I have used a 12 inch x 9 inch individual traybake tray, (see image below). You can use a 8 inch x 8 inch tray instead, the cooking time for the shortbread will be the same. The caramel is simply poured over the shortbread layer once the shortbread has completely cooled. Then once the caramel has cooled and you have melted the chocolate, poor the white chocolate over one half, and the milk chocolate over the other, then use a cocktail stick to marble the chocolate by running it from one side to the other of the chocolate. Once the chocolate has set turn out the traybake and cut into 12 pieces.

Chocolate topping

  • Take 200 grams of milk chocolate and break into small pieces. Place in a heatproof bowl and take a small pan and fill it with water to a depth of approximately 2cm. Place the bowl of chocolate on top of the pan. (The bowl must not touch the water otherwise it will burn the chocolate)
  • Then put the pan on a medium heat and leave the chocolate to melt.
  • Once it has just melted take the bowl off the pan and repeat steps one and two above with a separate heatproof bowl and 200 grams of white chocolate.
  • Place two teaspoons of the melted milk chocolate on one half of one of the individual shortbreads and caramel, spreading it over that half evenly.
