Biscoff Condensed Milk Slice Ingredients

For the Base
• Biscoff Biscuits – Provides the base structure and a caramel-spiced flavor; substitute with Digestives or any caramelized biscuit for similar taste.
• Butter – Contributes to richness; use unsalted for a balanced flavor that enhances the overall sweetness.

For the Filling
• Condensed Milk – Acts as the sweet binding agent that helps the slice set; no substitutes recommended unless using non-dairy alternatives.

Step‑by‑Step Instructions for Biscoff Condensed Milk Slice

Step 1: Prepare the Baking Tin
Start by lining a 20 cm square baking tin with baking paper, ensuring it overlaps the edges for easy removal later. Lightly grease the paper with unsalted butter to prevent sticking. This step is crucial for a smooth release once your Biscoff Condensed Milk Slice is set. Prepping the tin properly will make your clean-up effortless.

Step 2: Create the Biscuit Base
In a mixing bowl, crumble the Biscoff biscuits until they resemble fine crumbs. Melt some unsalted butter in a microwave or saucepan, then pour it over the crushed biscuits. Stir the mixture thoroughly until all crumbs are well coated. Transfer this crumbly blend into the prepared baking tin, pressing it firmly into an even layer to form a sturdy base for your slice.

Step 3: Combine the Filling Ingredients
In a large bowl, open a can of condensed milk and add chopped white chocolate and Biscoff spread. Microwave the mixture in short bursts of 20 seconds, stirring in between until everything is completely melted and smooth. This creates a luscious, creamy filling. Once combined, pour it over the compacted biscuit base, spreading it evenly with a spatula for a beautiful finish.

Step 4: Chill and Set
Place the baking tin in the refrigerator and chill it for at least 3 hours or preferably overnight. This helps the Biscoff Condensed Milk Slice set properly, ensuring the filling achieves a firm yet creamy texture. While it chills, the flavors meld beautifully, enhancing the indulgent taste of your dessert.

Step 5: Slice and Serve
Once set, take the tin out of the fridge and carefully lift the slice out using the edges of the baking paper. Place it on a cutting board and use a sharp knife to cut it into squares or bars. Ensure each slice has clean edges for an appealing presentation. Serve chilled for the best taste experience, and enjoy this delectable treat!

Biscoff Condensed Milk Slice Variations

Dairy-Free: Substitute the condensed milk and white chocolate with coconut milk and dairy-free chocolate for a vegan delight. The richness remains intact, ensuring no one misses the dairy!
Nutty Delight: Add a sprinkle of crushed almonds or hazelnuts on top before chilling. This will give a wonderful crunch and add a layer of flavor. Nuts add a lovely texture and nutty flavor that pairs beautifully with the Biscoff essence.
Chocolate Swirl: Drizzle melted dark chocolate over the top before setting. This creates a beautiful marbled effect and enhances the chocolate flavor wonderfully.
Caramel Drizzle: Drizzle some caramel sauce over the top just before serving for an extra indulgent touch of sweetness. The gooey caramel pairs perfectly with the Biscoff’s caramel hints, making it heavenly!
Add Spice: Mix in a pinch of cinnamon or nutmeg into the filling to elevate the spice profile. This kick of warmth adds depth, making each bite a cozy experience.
Nut-Free Twist: Use crushed pretzels for a sweet and salty contrast if you want to keep it nut-free. The saltiness builds a delightful balance against the sweetness of the slice, creating a flavor explosion.
Biscoff Crust: Combine crushed Biscoff biscuits with some rolled oats for a thicker crust texture that adds an interesting chewiness. The oats give it a wholesome feel while keeping that delightful Biscoff taste.
Mini Bites: Instead of a large slice, pour the mixture into mini muffin tins to create bite-sized treats. Perfect for parties or lunchboxes, these little morsels pack the same great flavor into a fun, shareable size.
