Step‑by‑Step Instructions for Biscoff Condensed Milk Slice
Step 1: Prepare the Pan
Line a 20 cm square baking tin with baking paper, ensuring it overhangs on the sides for easy removal later. Lightly grease the paper with a small amount of butter to prevent sticking. This preparation is crucial to achieving a flawless Biscoff Condensed Milk Slice that will pop out beautifully after setting.
Step 2: Make the Base
Crush the Biscoff biscuits into fine crumbs using a food processor or by placing them in a zip-top bag and hitting them with a rolling pin. Melt unsalted butter in a microwave or small saucepan, then combine it with the biscuit crumbs until well mixed. Press this mixture firmly into the base of the prepared tin, ensuring it’s even and compact for a sturdy foundation.
Step 3: Prepare the Filling
In a heatproof bowl, melt the white chocolate over a simmering pot of water or in the microwave, stirring until fully smooth. Once melted, mix in the condensed milk and Biscoff spread until you achieve a creamy consistency. Pour this luscious filling over the biscuit base, spreading it evenly with a spatula to ensure every bite of your Biscoff Condensed Milk Slice is rich and indulgent.
Step 4: Chill
Cover the tin with plastic wrap or foil, then place it in the refrigerator. Chill the mixture for at least 3 hours, or ideally overnight, to set completely. The filling should be firm to the touch when you’re ready to slice it, resulting in a perfectly structured dessert that’s easy to cut.
Step 5: Finish
Once set, carefully lift the slice out of the tin using the overhanging baking paper. Drizzle additional Biscoff spread or melted chocolate over the top for a decorative touch. Use a sharp knife to slice the Biscoff Condensed Milk Slice into squares for serving, ensuring each piece has that delectable drizzle for extra indulgence.
