Step‑by‑Step Instructions for Biscoff Millionaires Traybake
Step 1: Prepare the Base
Begin by preheating your oven to 180°C (350°F) and lining a rectangular baking tray (approximately 8×12 inches) with parchment paper for easy removal. In a large bowl, combine crushed digestive biscuits and melted unsalted butter until well mixed. Press this mixture firmly into the tray to form an even base. Bake in the preheated oven for 10–12 minutes or until it’s lightly golden and fragrant.
Step 2: Make the Caramel Layer
In a medium saucepan over medium heat, combine granulated sugar and double cream, stirring continuously until the sugar dissolves. Keep cooking until the mixture thickens and turns a rich amber color, about 5–7 minutes. Once achieved, remove it from the heat and gently fold in the creamy Biscoff spread until fully combined. Pour this luscious caramel over the cooled biscuit base, ensuring it is evenly spread.
Step 3: Add the Chocolate Layer
While the caramel layer sets, melt your semi-sweet or dark chocolate gently in a heatproof bowl set over a pot of simmering water or in the microwave in 30-second bursts until smooth. Once melted, you can stir in a tablespoon of butter for added silkiness. Pour this velvety chocolate over the set caramel layer, using a spatula to spread it evenly across the surface.
Step 4: Garnish
Before the chocolate sets, sprinkle generous crumbles of Biscoff cookies over the chocolate layer. This will create a delightful crunch that complements the creaminess of the Biscoff Millionaires Traybake. Let it rest for a few minutes to allow the cookie crumbles to adhere to the chocolate.
Step 5: Set and Serve
Allow the entire traybake to cool at room temperature for about 30 minutes, then transfer it to the refrigerator. Let it chill for at least 2 hours, which helps each layer set properly. Once fully chilled, slice into squares or rectangles with a sharp knife and serve this indulgent treat to your eager family and friends!
