Ingredients You’ll Need
This recipe uses simple pantry ingredients, yet the flavor feels rich and indulgent.
Base ingredients for a chewy, buttery slice
You will need sweetened condensed milk, salted butter, and Lotus Biscoff spread. These melt together into a smooth base. Then, crushed Lotus Biscoff biscuits add structure and crunch.
You can crush the biscuits in a processor for fine crumbs. However, you can also crush them in a sealed bag for a mix of textures. As a result, the base holds together while staying slightly crunchy.
Chocolate Biscoff topping and optional drizzle
For the topping, use milk chocolate and a little vegetable oil. This helps the chocolate melt smoothly. Then, stir in extra Biscoff spread to boost flavor.
You can also drizzle warmed Biscoff on top before serving. This adds a glossy finish and a more indulgent look.
How to Make Biscoff Condensed Milk Slice Step-by-Step
This method is simple, and each step builds rich flavor and texture.
Preparing the tin and melting the base mixture
First, line and grease a square baking tin with baking paper. Leave extra paper hanging over the edges for easy removal later.
Next, gently heat condensed milk and butter together. Stir until melted, then add Biscoff spread. Keep stirring until the mixture becomes smooth and creamy.
Mixing in biscuits and forming the base layer
Then, fold in the crushed biscuits. Mix until everything is fully coated. The texture will become thick and slightly sticky.
After that, press the mixture firmly into the tin. Smooth the surface evenly so the base sets properly.
Creating the chocolate topping and assembling
Now, melt the chocolate with vegetable oil in short bursts. Stir often to keep it smooth. Then, mix in extra Biscoff spread.
Pour the topping over the base and spread evenly. This creates a rich chocolate layer that pairs perfectly with the biscuit base.
Chilling, setting, and slicing clean portions
Place the slice in the fridge for a few hours until firm. Then, lift it out using the paper.
Let it sit briefly at room temperature before slicing. If desired, drizzle extra Biscoff on top before serving.
Pro Tips for the Best Texture and Flavor
Small details can make your Biscoff Condensed Milk Slice even better.
How to crush biscuits evenly and efficiently
Use a processor for even crumbs. However, crushing by hand gives a mix of textures. Both work well, so choose based on preference.
Getting smooth chocolate without burning
Always melt chocolate slowly and stir often. This prevents burning. Also, adding oil helps keep the texture silky and easy to spread.
Tricks for clean slicing and easy removal
Line the tin well so removal is easy. Then, let the slice soften slightly before cutting. As a result, you get clean and neat slices every time.
Easy Variations and Substitutions
You can easily adapt this recipe based on your taste.
Switching chocolate types or adding toppings
Try dark or white chocolate instead of milk chocolate. Also, add crushed biscuits or nuts on top for extra crunch.
Making it extra indulgent with layers or mix-ins
Add a second layer or mix in chocolate chips. Meanwhile, swirling extra Biscoff into the base adds even more flavor.
Ingredient swaps based on what you have
If needed, use similar spiced biscuits instead of Biscoff biscuits. You can also try other spreads, although Biscoff gives the classic taste.
Storage and Make-Ahead Tips
This dessert is great for prepping ahead and storing easily.
How to store in the fridge for freshness
Store the Biscoff Condensed Milk Slice in an airtight container in the fridge. It stays fresh for several days.
Freezing and thawing without losing texture
You can freeze slices for longer storage. Then, thaw them in the fridge before serving. This keeps the texture firm.
Serving tips for best taste and consistency
Let the slice sit out for a few minutes before serving. This softens it slightly and improves the texture.
