Step‑by‑Step Instructions for Biscoff Condensed Milk Slice

Step 1: Prepare the Pan
Start by lining a 20 cm square baking tin with baking paper, allowing some overhang on the sides for easy removal later. Lightly grease the paper with cooking spray or a dab of butter to prevent sticking. This simple preparation will ensure your Biscoff Condensed Milk Slice comes out perfectly and keeps its shape.

Step 2: Make the Base
Crush the Biscoff biscuits into fine crumbs using a food processor or by placing them in a zip-lock bag and rolling over them with a rolling pin. Combine the crushed biscuits with melted unsalted butter in a mixing bowl until evenly mixed. Press this buttery mixture firmly into the bottom of the prepared baking tin to create a solid base.

Step 3: Create the Filling
In a large mixing bowl, combine the sweetened condensed milk, melted white chocolate, and Biscoff spread. Use a spatula to mix everything together until the mixture is completely smooth and well combined, ensuring there are no lumps. This decadent filling is what will give your Biscoff Condensed Milk Slice its rich taste and creamy texture.

Step 4: Set the Mixture
Pour the smooth filling over the prepared biscuit base, using a spatula to evenly spread it across the surface. Level the top gently and cover with cling wrap, making sure it doesn’t touch the filling. Place the tin in the refrigerator for at least 3 hours or overnight to allow the Biscoff Condensed Milk Slice to set properly.

Step 5: Serve
Once fully set, remove the slice from the pan using the paper overhang. Place it on a clean cutting board and cut into small squares or bars using a sharp knife for clean edges. The beautifully layered Biscoff Condensed Milk Slice is now ready to be enjoyed, whether at a gathering or as a delicious treat for yourself!
