Ingredients
Method
- In a mixing bowl, combine the crushed digestive biscuits, melted butter, and sugar until the mixture resembles wet sand. Press firmly into the base of a lined 9×9-inch traybake tin to form an even layer. Refrigerate for 30 minutes to set.
- In a medium saucepan over medium heat, melt the butter, brown sugar, and sweetened condensed milk, stirring constantly. Once bubbling, reduce heat and continue stirring for 5–7 minutes until thickened and deepened in color.
- Remove from heat and stir in the Biscoff spread until smooth. Pour over the chilled base and spread evenly. Refrigerate for at least 1 hour to set the caramel layer.
- Melt the milk chocolate and Biscoff spread together using a double boiler or microwave in short intervals, stirring frequently until smooth.
- Pour the melted chocolate mixture over the set caramel layer and spread evenly with a spatula. Refrigerate for 2 hours, or until fully set.
- Once set, remove from the refrigerator and slice into squares or rectangles using a sharp knife. Serve and enjoy.
