Salt (¼ teaspoon + ¼ teaspoon fine sea salt): Just a pinch to enhance flavors and balance the sweetness.
Light brown sugar (½ cup / 100 g): Gives the caramel layer its deep, sugary flavor and sticky texture.
Sweetened condensed milk (1 tin / 397 g): Creates the thick, gooey caramel with a lovely creamy mouthfeel.
Lotus Biscoff spread (3 tablespoons total): Intensifies that iconic taste throughout the caramel and the chocolate topping.
Milk chocolate (250 g): Melts into a smooth, velvety topping that contrasts the chewy caramel and crunchy biscuit base.

How to Make Biscoff Millionaires Shortbread Recipe

Step 1: Prepare the Biscuit Base

Start by lining an 8-inch square baking pan with parchment paper to ensure easy removal later. Blitz the Lotus Biscoff biscuits in a food processor until they turn into fine crumbs—this gives you that classic shortbread texture without baking. Mix the crushed biscuits with melted butter and a pinch of salt, then press firmly into the pan using a glass or measuring cup. Pop the base in the fridge to chill and set while you prepare the caramel, ensuring your layers hold perfectly firm.

Step 2: Make the Biscoff Caramel

This is where the magic happens. In a heavy-bottomed saucepan, melt butter over low-medium heat and stir in the light brown sugar until it’s completely dissolved—keep an eye out to feel for that smooth texture without grainy bits. Next, slowly incorporate the sweetened condensed milk, raising the heat just below medium. Stir continuously until the mixture bubbles and thickens to a beautiful golden caramel, about 110°C if you’re using a candy thermometer. Quickly remove from heat and whisk in two tablespoons of Biscoff spread and the sea salt to infuse that signature cookie spice right into your caramel. Pour this luscious layer over your chilled biscuit base, gently tilting the pan to even it out, then chill again.

Step 3: Create the Chocolate Topping

The final indulgent layer combines creamy milk chocolate with a swirl of Biscoff spread for extra flair. Melt the chocolate carefully in the microwave in short bursts, stirring thoroughly to avoid overheating. Warm the remaining tablespoon of Biscoff spread until it’s pourable. Pour the melted chocolate over the firm caramel, then drizzle the runny Biscoff spread on top. Use a knife to gently swirl the two together, creating a beautiful marbled effect without disturbing the layer below. Once complete, place your tray back in the fridge for at least 1-2 hours so everything can set to perfection.

Each dessert has three layers: the bottom layer is a crumbly golden brown crust, the middle layer is a smooth, thick light caramel color, and the top layer is a rich chocolate with a slightly swirled pattern. The bars have clean edges and look soft yet firm. A spoon with some caramel spread sits nearby, hinting at the dessert’s creamy texture.

Garnishes

While this dessert is stunning on its own, a few thoughtful garnishes can elevate it further. Consider a light sprinkle of crushed Biscoff biscuits or a pinch of flaky sea salt over the chocolate layer right before it sets for a delightful crunch. A small dollop of whipped cream or a dusting of cocoa powder can add visual appeal and complement the sweetness without overpowering the rich layers.

Side Dishes

Because this Biscoff Millionaires Shortbread Recipe is so rich, pairing it with lighter side dishes works beautifully. Fresh berries or a tangy raspberry coulis help cut through sweetness and refresh the palate. A simple scoop of vanilla ice cream adds creaminess and temperature contrast, while a cup of robust coffee or spiced chai tea rounds out the indulgent experience with warmth and spice.

Creative Ways to Present

Presentation is half the fun, right? Cut your shortbread into small, neat squares for pretty finger food perfect for parties or afternoon teas. You can also stack them with parchment paper in between layers inside a beautiful tin or clear box for a gorgeous homemade gift. For a festive twist, drizzle with white chocolate or add edible gold leaf to surprise and delight your guests.

Make Ahead and Storage

Storing Leftovers

Leftover Biscoff Millionaires Shortbread Recipe keeps wonderfully well in an airtight container in the refrigerator for up to five days. The chill helps maintain the caramel’s chewy texture and keeps the chocolate topping firm, so just be sure to serve it slightly cooled or at room temperature for the best melt-in-your-mouth feel.

Freezing

If you want to save these treats for later, freezing is a great option. Wrap the shortbread tightly in plastic wrap and place it in a sealed container or freezer-safe bag. It will hold up to two months frozen without losing any flavor or texture. When you’re ready to enjoy, thaw it slowly in the fridge overnight to prevent sweating or stickiness.

Reheating

Though this dessert is best served chilled or at room temperature, if you desire a softer, gooier experience, you can warm pieces gently in the microwave for 10-15 seconds. Be cautious not to overheat, as the chocolate can seize or the caramel become too runny.

FAQs

Can I use other types of biscuits for the base?

While Lotus Biscoff biscuits give this recipe its unique spicy-sweet flavor, you can substitute with graham crackers or digestive biscuits. Just keep in mind that the iconic taste may be a little different.

Is it necessary to use sweetened condensed milk for the caramel?

Yes, sweetened condensed milk is key to achieving that rich, creamy caramel texture without resorting to heavy cream or making caramel from scratch. It adds sweetness and thickness perfectly suited for this layered treat.

Can I make this recipe dairy-free?

With some ingredient swaps, yes. Try using dairy-free butter and a plant-based condensed milk alternative, plus dairy-free chocolate. The taste may vary slightly, but the overall concept remains delicious.

How do I prevent the caramel from separating?

Keep the heat gentle and stir continuously while cooking your caramel layer. This helps everything combine smoothly and prevents the butter and sugar from breaking apart. Using a heavy-bottomed pan also reduces the risk of scorching.

Can I prepare this dessert ahead for a party?

Absolutely! This Biscoff Millionaires Shortbread Recipe actually benefits from chilling times, making it an excellent make-ahead dessert. Prepare it a day or two before, and it will be set perfectly for serving your guests.

This Biscoff Millionaires Shortbread Recipe is truly a celebration of textures and flavors, perfect for anyone who loves a sweet treat with a twist.
