Full Recipe:

Ingredients

For the shortbread layer

• 1½ cups of crushed digestive biscuits or graham crackers

• ¼ cup melted butter

• 2 tablespoons sugar

For the caramel layer

• ½ cup unsalted butter

• ½ cup brown sugar

• ½ cup sweetened condensed milk

• ¼ cup Biscoff (cookie butter) spread

For the chocolate layer

• 1 cup milk chocolate, melted

• ½ cup Biscoff spread

Directions

• Prepare the base: Combine the crushed biscuits, melted butter, and sugar until the mixture resembles damp sand. Press firmly into a lined 9×9-inch pan, smoothing evenly. Chill for at least 30 minutes to firm up the base before adding the next layer.

• Make the caramel: In a saucepan, stir together the butter, brown sugar, and condensed milk over medium heat until smooth. Once the mixture begins bubbling, reduce heat and simmer, stirring consistently for 5–7 minutes until the caramel thickens, turns golden, and takes on a glossy finish. Remove from heat and immediately blend in the Biscoff spread. Pour the hot caramel over the chilled base, spreading it evenly. Refrigerate for at least 1 hour to set.

• Add the chocolate topping: Gently melt the milk chocolate and Biscoff spread together, either using a double boiler or by microwaving in short bursts, stirring often to avoid scorching. Spread this velvety mixture evenly over the firm caramel layer.

• Chill and slice: Return the traybake to the fridge for about 2 hours until fully set. Use a sharp knife slightly warmed under hot water and wiped dry between cuts to achieve neat edges. Slice into squares or rectangles and serve chilled.

Why This Recipe Stands Out

What makes this Biscoff Millionaire’s Traybake so irresistible is the way it transforms a few simple ingredients into something that feels extravagant. Unlike traditional millionaire’s shortbread, this version introduces the warm, spiced caramelized flavor of Biscoff spread. The cookie butter adds depth and complexity, creating a dessert that is familiar yet exciting. The layered format delivers contrast in every bite: the crumbly biscuit base, smooth caramel, and glossy chocolate topping harmonize beautifully, making it difficult to resist going back for seconds. Best of all, this recipe requires no baking, which means the oven can stay off, making it a quick and convenient treat year-round.

This traybake is also versatile. It fits equally well at casual gatherings, elegant dinner parties, or festive holiday spreads. A simple square on a plate looks polished enough to impress guests, while a larger tray can be sliced into bite-sized portions for a dessert buffet. Whether enjoyed as a personal indulgence or served as the centerpiece at an event, its visual appeal and decadent flavor make it a dessert worth remembering.

The Benefits of the Ingredients

Each ingredient in this traybake contributes to its layered richness. The base of digestive biscuits or graham crackers brings a buttery, slightly sweet crunch. When mixed with melted butter and sugar, they form a foundation that is sturdy yet crumbly enough to balance the soft caramel above.

The caramel is where the magic happens. A blend of butter, brown sugar, and condensed milk creates a silky-smooth filling with a depth of sweetness. Adding Biscoff spread to the caramel introduces unique spiced notes of cinnamon and caramelized sugar, giving it an unforgettable twist.

The chocolate topping ties everything together. Milk chocolate offers a creamy sweetness, while the Biscoff spread mixed into it enhances the spiced, caramel undertones. This clever pairing makes the chocolate richer, silkier, and more flavorful than a plain topping. For those who prefer a less sweet bite, dark chocolate can be used as a substitute, providing a pleasant bitterness that balances the caramel.

Beyond taste, the use of these ingredients makes the recipe approachable. Nothing requires advanced baking skills. Instead, familiar pantry staples come together to create a dessert that tastes far more impressive than the effort suggests.

Cooking Tips

To ensure the best results, take your time with each layer. Press the biscuit base firmly into the tray so it holds its shape when cut. If the base is too loose, the bars may crumble when sliced. Allowing the base to chill completely before adding caramel is essential for neat layering.

Caramel can be tricky, but patience is key. Stir the mixture continuously to prevent burning, and keep the heat moderate. When the caramel has thickened and developed a golden hue, you’ll know it’s ready. Stirring in the Biscoff spread off the heat ensures it melts smoothly and blends evenly.

The chocolate layer also benefits from care. Melting chocolate with Biscoff spread slowly, either over a double boiler or in short microwave bursts, prevents scorching. Spread it quickly yet gently over the chilled caramel to avoid pulling at the layer beneath. For a flawless finish, tilt the pan slightly to let the chocolate self-level before chilling.

When it comes time to slice, use a sharp knife warmed in hot water. Wipe the blade between cuts for clean edges. This extra step makes the traybake look professional and presentable, especially when serving to guests.

Serving Suggestions

This traybake is a joy to serve in many ways. Chilled squares highlight the firm layers and clean edges, perfect for sharing at coffee breaks or tea times. For a softer bite, let the traybake sit at room temperature for a few minutes before serving, which makes the caramel gooier and more indulgent.

Pairing this dessert with drinks enhances its enjoyment. A strong black coffee or espresso balances the sweetness beautifully, while a cup of chai complements the warm spices in the Biscoff spread. For a more festive presentation, serve alongside fresh berries, which add a refreshing tartness that contrasts the rich caramel and chocolate.

If you want to elevate the dessert for a special occasion, top the set chocolate layer with crushed Biscoff cookies or a drizzle of melted white chocolate before slicing. For gatherings, consider cutting the traybake into bite-sized squares and arranging them on a dessert platter with other small treats like truffles, macarons, or petit fours. It also makes a lovely edible gift when wrapped in parchment paper and tied with a ribbon.

Conclusion

The Biscoff Millionaire’s Traybake proves that indulgence doesn’t need to be complicated. Its layers of biscuit, caramel, and chocolate combine effortlessly into a treat that feels gourmet yet requires little time or skill to make. Each bite is a balance of crunch, creaminess, and silky smoothness, with the distinctive flavor of Biscoff setting it apart from other traybakes.

This dessert’s adaptability ensures it can be enjoyed in countless ways, whether chilled for neat squares, softened for a gooier treat, or customized with dark chocolate or sea salt. It’s a reliable recipe for entertaining, gifting, or simply indulging at home.
