Step-by-Step Instructions
Making the Biscoff Millionaire’s Traybake is simple and rewarding. Follow these steps for the perfect no-bake dessert:
Use a warm, sharp knife to cut into squares and enjoy!
Prepare the Biscuit Base:
Crush 250 grams of Biscoff biscuits into fine crumbs using a food processor or by placing them in a sealed bag and using a rolling pin.
Mix the crushed biscuits with 100 grams of melted unsalted butter until evenly combined.
Press the mixture firmly into a lined 20 x 20 cm baking tray, creating an even, compact base.
Place the tray in the fridge to chill for 30 minutes, allowing the base to set.

In a medium saucepan, combine 397 grams of sweetened condensed milk, 30 ml (2 tablespoons) of golden syrup, 100 grams of light brown sugar, and 50 grams of unsalted butter.
Heat over medium heat, stirring continuously to prevent burning. Cook for 10–12 minutes until the mixture thickens and turns a golden caramel color.
Pour the caramel evenly over the chilled biscuit base.
Return the tray to the fridge and chill for 1–2 hours until the caramel layer is firm.
Prepare the Chocolate Topping:
Melt 200 grams of milk chocolate with 45 grams (3 tablespoons) of Biscoff spread in a heatproof bowl over simmering water or in short bursts in the microwave.
Stir until smooth and well combined.
Pour the chocolate mixture over the set caramel layer and spread evenly.
Optional: Sprinkle crushed Biscoff biscuits on top for added crunch.
Final Chill and Serve:
Refrigerate the traybake for several hours or overnight until the chocolate topping is fully set.

Yes, you can make the caramel layer a day or two ahead. Store it covered in the fridge and gently warm before spreading over the biscuit base for easier spreading.

To achieve clean, neat slices, use a sharp knife warmed under hot water and wiped dry before each cut. This prevents the chocolate topping from cracking or sticking to the knife.
