Biscoff Millionaire’s Traybake Ingredients
For the Base
• Biscoff biscuits – These create the base structure; substitute with Digestive biscuits or graham crackers if needed.
• Unsalted butter (melted) – Binds the biscuit crumbs for a perfect base; try coconut oil for a dairy-free twist.
For the Caramel Layer
• Sweetened condensed milk – Forms the gooey caramel; homemade caramel can replace for extra richness.
• Light brown sugar – Adds depth and sweetness; granulated sugar can be used for a different texture.
• Biscoff spread – Elevates the flavor and creaminess; experience with almond or peanut butter for a unique variation.
For the Topping
• Milk chocolate – Provides a silky sweet finish; switch it out for dark chocolate for a richer taste.
• White chocolate (optional) – For decorative drizzling; skip it for a simpler look.
Step‑by‑Step Instructions for Biscoff Millionaire’s Traybake
Step 1: Prepare the Biscuit Base
Start by crushing the Biscoff biscuits into fine crumbs using a food processor or by placing them in a plastic bag and rolling with a rolling pin. Combine the crumbs with melted unsalted butter until fully incorporated. Press the mixture firmly into the base of a lined 8×8 inch baking tin. Chill the base in the refrigerator for 20 minutes until set and firm to the touch.
Step 2: Cook the Caramel Layer
In a medium saucepan, add the sweetened condensed milk, light brown sugar, and Biscoff spread over medium heat. Stir continuously for 5-7 minutes as the mixture thickens and bubbles gently, ensuring it doesn’t burn. The goal is to achieve a smooth, gooey caramel consistency with an inviting golden hue. Once ready, remove it from heat and let it cool slightly before spreading.
Step 3: Spread the Caramel
Pour the thick caramel layer evenly over the chilled biscuit base, ensuring it’s well-distributed across the surface. Use a spatula to smooth the top for an even layer. Return the tray to the refrigerator, allowing the caramel to set for 20-30 minutes. The caramel should be firm yet sticky when you take it out, creating the perfect base for the chocolate topping.
Step 4: Melt the Chocolate
Break the milk chocolate into pieces and place them in a heatproof bowl over a pot of gently simmering water (double boiler method). Stir occasionally until the chocolate is completely melted and smooth. For a quick alternative, microwave the chocolate in short bursts, stirring in between. Let it cool slightly before you move to the next step to avoid melting the caramel base.
Step 5: Add the Chocolate Layer
Once the caramel has set, pour the melted milk chocolate over the top, spreading it out evenly with a spatula to cover the entire surface. Ensure a nice, glossy layer that beautifully contrasts with the caramel below. Return the traybake to the refrigerator for another 30 minutes or until the chocolate topping is firm to the touch.
Step 6: Optional Drizzle with White Chocolate
If desired, melt white chocolate using the same method as the milk chocolate. Drizzle the melted white chocolate over the top of the hardened chocolate layer using a fork or piping bag to create decorative swirls. This added touch brings elegance and visual appeal to your Biscoff Millionaire’s Traybake.
Step 7: Chill and Cut
Once the white chocolate drizzle has set, place the traybake in the refrigerator for at least 2 hours to ensure all layers are firm. When ready, use a hot knife to slice through the traybake into squares or bars. This technique helps achieve clean, crisp edges, making each piece a delightful treat to serve.

Make Ahead Options
The Biscoff Millionaire’s Traybake is perfect for meal prep enthusiasts! You can prepare the entire dessert up to 3 days in advance and store it in an airtight container in the refrigerator to maintain freshness. To ensure the layers remain intact, refrigerate each component separately—prepare the biscuit base and caramel layer ahead, then pour over the chocolate when ready to serve. If you need even more flexibility, these traybakes freeze well for up to 3 months; just thaw in the refrigerator overnight before serving. Simply cut into squares after chilling for 2 hours, and you’ll have a delectable treat that’s just as delicious as freshly made!
