Prep Time10 minutes
Cook Time35 minutes
Servings: 25 squares

Ingredients

Shortbread Base

  • 150 g Plain flour
  • 130 g Unsalted butter cold and cubed
  • 75 g Cornflour
  • 75 g Caster sugar

Caramel Layer

  • 395 g Sweetened condensed milk 1 can
  • 45 g Brown sugar
  • 60 g Unsalted butter

Chocolate Top

  • 200 g Milk chocolate best quality, chopped
  • 50 g White chocolate best quality, chopped

Instructions

Shortbread Base

  • Pre-heat the oven to 165°C (fan forced).
  • Line a 20cm square cake tin with baking paper.
  • In a stand mixer, combine the butter and sugar to form a paste.
  • Add the flour and cornflour, then mix on low until it just comes together. Do not overmix.
  • Tip the dough into the prepared tin, then press down flat, spreading to the corners. You can use the back of a spoon to smooth the dough and straighten the edges.
  • Bake for 15 mins, then remove from the oven to cool in the tin.
  • Turn heat down to 140°C fan forced and make the caramel.

Caramel Layer

  • Place the condensed milk, sugar and butter in a small saucepan and stir with a silicone spatula over low heat until the butter has melted and the mixture is smooth.
  • Increase the heat a little and continue to quickly and carefully stir the caramel until it thickens and bubbles. This will take about 5 minutes. Be sure to stir into the edges of the saucepan to ensure the caramel doesn't stick and produce brown spots.
  • Pour the caramel onto the partly cooled, cooked shortbread and bake for another 12 minutes. It will bubble as it bakes.
  • Remove from the oven and allow to cool in the tin. Once cool enough to handle, you can place it in the fridge for an hour or two.
  • Once chilled, you can top with the chocolate.

Chocolate Top

  • Place the milk chocolate in a microwave safe bowl and heat for 1 minute. Stir well, then heat for 10 second bursts, until melted.
  • In another microwave safe bowl, melt the white chocolate in 20 second, then 10 second bursts (it burns easily!)
  • Pour the melted milk chocolate onto the caramel layer, then drizzle over the melted white chocolate. Use a skewer to swirl the white chocolate through, creating a marbled effect.
  • Chill until set, then carefully cut with a hot knife. Store in an airtight container.
