Ingredients for the no-bake biscoff caramel slice

Before diving into the method, letโ€™s take a closer look at the ingredients youโ€™ll need. Understanding each component will help ensure your no-bake Biscoff caramel slice comes out just right.

For the Biscoff Base:

  • 300g Biscoff biscuits: These iconic spiced cookies form the foundation of the slice. Their crunchy texture and caramelized flavor perfectly complement the other layers.
  • 150g unsalted butter (melted): The butter helps bind the crushed cookies into a firm base while adding richness.

For the Caramel Layer:

  • 1 can (395g) sweetened condensed milk: This is the base of the caramel. Sweetened condensed milk thickens and turns into a silky caramel when combined with butter and sugar.
  • 150g unsalted butter: Adds creaminess to the caramel, making it rich and indulgent.
  • 2 tablespoons golden syrup: Provides a subtle sweetness and prevents the caramel from crystallizing, ensuring it stays smooth.
  • 100g brown sugar: Deepens the flavor of the caramel, giving it a more complex, toffee-like taste.

The Chocolate Topping:

  • 200g dark chocolate: A slightly bitter chocolate topping balances the sweetness of the caramel, creating a harmonious flavor profile.
  • 2 tablespoons vegetable oil: Helps the chocolate topping set with a smooth and shiny finish, making it easier to cut into slices without cracking.

Step-by-Step Guide to Making a No-Bake Biscoff Caramel Slice

1. Prepare the Biscoff Base

The first layer of this indulgent dessert is a crunchy, buttery Biscoff cookie base that will hold up the rich caramel and chocolate layers. Hereโ€™s how to create the perfect foundation for your no-bake slice.

Crush the Biscoff Biscuits: Start by placing the Biscoff biscuits in a food processor that crushes them into fine crumbs. If you donโ€™t have a food processor, you can also place the cookies in a zip-lock bag and crush them using a rolling pin. Youโ€™re aiming for a sand-like texture with no large chunks.

Tip: If you like a bit of extra texture, you can leave a few slightly larger pieces of Biscoff in the mix, but make sure most of the crumbs are fine so the base holds together well.

Combine with Melted Butter: Melt the butter in the microwave or in a small saucepan over low heat. Pour the melted butter over the crushed Biscoff biscuits and mix well until the crumbs are evenly coated and resemble wet sand.

Press the Mixture into a Pan: Line a square or rectangular baking pan (about 20×20 cm) with parchment paper, making sure to leave some overhang for easy removal later. Press the Biscoff-butter mixture firmly into the base of the pan using the back of a spoon or the bottom of a flat glass. This will create an even, compact layer.

Tip: Ensure the base is tightly packed so it holds together when sliced later. Place the pan in the fridge while you prepare the caramel layer to allow the base to set.

2. Make the Caramel Layer

The next step is creating the rich buttery caramel layer. This middle layer is what gives the slice its signature indulgence and sweetness.

Melt the Butter, Sugar and Golden Syrup: In a medium saucepan, combine the butter, brown sugar and golden syrup. Cook over low heat, stirring constantly until the butter has melted and the sugar has dissolved completely. This step ensures the caramel has a smooth glossy consistency.

Tip: Stirring constantly is key to prevent the sugar from burning and to achieve a silky caramel.

Add the Sweetened Condensed Milk: Once the butter, sugar, and syrup mixture is smooth, stir in the sweetened condensed milk. Increase the heat to medium and cook for about 7-10 minutes, stirring continuously. The caramel will start to thicken and take on a slightly darker color.

Tip: Donโ€™t rush this step. Cook the caramel slowly to avoid burning and make sure it thickens to the point where it coats the back of a spoon. If itโ€™s too runny, it wonโ€™t set properly on the Biscoff base.

Pour the Caramel Over the Base: Once the caramel is thick and smooth, remove the Biscoff base from the fridge and pour the caramel over the top. Spread it evenly using an offset spatula or the back of a spoon to ensure the entire base is covered.

Chill to Set: Place the pan back in the fridge for at least 1-2 hours, or until the caramel has completely set. It should be firm to the touch but not rock hard.

3. Prepare the Chocolate Topping

The final layer of this no-bake dessert is a glossy rich chocolate topping that adds the perfect amount of indulgence to each bite.

Melt the Chocolate: Break the dark chocolate into small pieces and place it in a heatproof bowl. Melt the chocolate either in the microwave in 20-second intervals, stirring between each, or by using the double-boiler method (placing the bowl over a pan of simmering water).

Tip: Be careful not to overheat the chocolate. Dark chocolate can seize if heated too quickly, so melt it slowly and stir frequently.

Stir in Vegetable Oil: Once the chocolate is fully melted, stir in the vegetable oil. This will help create a smooth, shiny finish on the chocolate and make slicing the caramel slice easier without the chocolate cracking.

Pour Over the Caramel Layer: Remove the pan from the fridge and pour the melted chocolate over the set caramel layer. Tilt the pan gently or use a spatula to spread the chocolate evenly across the top.

Chill One Last Time: Place the pan back in the fridge for about 30 minutes to an hour, or until the chocolate is firm but not too hard.

4. Slice and Serve

Now that your no-bake Biscoff caramel slice is fully set, itโ€™s time to slice and serve this decadent treat.

Remove from the Pan: Using the parchment paper overhang, carefully lift the slice out of the pan and place it on a cutting board.

Slice Cleanly: To get clean sharp slices, use a sharp knife thatโ€™s been run under hot water and then dried. The heat from the knife will help glide through the chocolate without cracking it. Slice the caramel slice into small squares or rectangles; these treats are quite rich, so smaller pieces work well.

Serve: Arrange the slices on a platter and serve at room temperature. The combination of the crunchy Biscoff base, the rich caramel center, and the smooth chocolate top makes each bite a blissful experience.

Tips and Variations

Here are a few tips and variations to help you customize this no-bake Biscoff caramel slice to your liking.

  • Milk Chocolate Variation: If you prefer a sweeter topping, swap the dark chocolate for milk chocolate. Keep in mind that this will make the overall dessert sweeter, so consider reducing the sugar in the caramel layer slightly.
  • Add a Sprinkle of Salt: For a salted caramel twist, sprinkle a pinch of flaky sea salt over the chocolate layer just before it sets. The salt will balance the sweetness and add a sophisticated touch.
  • Peanut Butter Layer: For an extra indulgent twist, you can add a thin layer of peanut butter on top of the caramel before pouring over the chocolate. The nutty flavor pairs beautifully with the Biscoff and caramel.
  • White Chocolate Drizzle: For a decorative touch, melt a little white chocolate and drizzle it over the dark chocolate layer.

This layered dessert combines the irresistible crunch and spiced flavor of Biscoff cookies with a silky smooth caramel layer and a rich, chocolatey top. It’s perfect for those who want a show-stopping dessert without the hassle of baking.
