Ingredients

Scale

Cookie Base

  • 275 g plain flour
  • 1 tsp bicarbonate of soda
  • 1/2 tsp salt
  • 1 tbsp cornflour
  • 115 g unsalted butter
  • 55 g granulated sugar
  • 135 g light brown sugar
  • 1 medium egg
  • 1 tsp vanilla extract
  • 100 g white chocolate chips
  • 100 g milk chocolate chips
  • 100 g dark chocolate chips

Caramel Layer

  • 200 g unsalted butter
  • 3 tbsp caster sugar
  • 4 tbsp golden syrup
  • 397 g condensed milk (one tin)

Chocolate Topping

  • 100 g white chocolate
  • 100 g milk chocolate
  • 100 g dark chocolate

Instructions

  1. Preheat and Prepare: Preheat your oven to 190°C (170°C fan). Line a 9×9 inch square baking tin with parchment paper and set aside.
  2. Mix Dry Ingredients: In a bowl, whisk together the plain flour, bicarbonate of soda, salt, and cornflour until evenly combined.
  3. Create Cookie Dough Base: In a larger bowl, melt the butter. Add granulated and light brown sugars, whisking for about 2 minutes until sugars begin to dissolve and the mixture is smooth. Add the egg and vanilla extract, whisk again briefly until smooth.
  4. Incorporate Dry Mix and Chocolate Chips: Add the dry ingredients and all chocolate chips (white, milk, and dark) to the wet mixture. Fold gently with a spatula until a thick cookie dough is formed.
  5. Bake Cookie Base: Press the cookie dough evenly into the prepared tin and bake for 18-22 minutes, or until the top looks dry and set. Remove from oven and allow to cool.
  6. Make Caramel Layer: In a large saucepan over medium heat, combine condensed milk, unsalted butter, caster sugar, and golden syrup. Stir frequently until sugar dissolves completely.
  7. Boil Caramel: Increase heat to high and bring mixture to a boil. Boil for 5-7 minutes, stirring constantly to prevent sticking or burning. The caramel is ready when it thickens to a soft fudge texture and turns a slightly darker golden colour. Exercise caution as mixture will be very hot.
  8. Pour and Set Caramel: Pour the hot caramel evenly over the cooled cookie base. Leave to set at room temperature for 1-2 hours.
  9. Melt Chocolate Toppings: Carefully melt white, milk, and dark chocolates until smooth, preferably in short bursts in the microwave to avoid burning.
  10. Decorate with Chocolate: Drizzle the melted chocolates over the set caramel layer in a decorative swirly pattern or as desired. Allow the chocolate to set fully at room temperature or in the fridge before slicing and serving.

Notes

  • Make sure to stir the caramel constantly while boiling to prevent it from burning or catching on the pan.
  • Use a sharp knife warmed in hot water to get clean cuts when slicing the bars once fully set.
  • The bars keep well in an airtight container at room temperature for up to 5 days or refrigerated for up to a week.
  • Microwave chocolate cautiously in 20-second increments, stirring in between to avoid overheating and burning.
  • If caramel is too thick to spread easily, slightly warm it again over low heat to soften before pouring.
