Biscoff Baking

Biscoff is one of mine and my families favourite so you may or may not see more biscoff recipes coming very soon! Heads up, you absolutely will be seeing more biscoff recipes!

A biscoff is a type of spiced caramel biscuit, also known as a speculoos cookie, that originated in Belgium. They are known by their unique caramel and spice flavour, often including cinnamon, ginger, cloves, and nutmeg, along with a crispy texture. Biscoff also comes as a delicious spread, for this recipe I used both the biscuits and the spread!

How to Make Triple Biscoff Millionaire’s Bars

Step 1- Make the biscoff biscuit base

Crush the Biscoff biscuits into fine crumbs (Using a rolling pin to crush them or a food processor). Mix with melted butter until fully combined. Press into a lined 8×8 inch baking tin and chill in the fridge while you prepare the caramel layer.

Step 2- Microwave Biscoff Caramel

In a microwaveable bowl, add your butter, golden syrup, condensed milk, sugar, and Biscoff spread. Microwave in short bursts (one minute each time) Stir Thoroughly every minute until thickened (about 8–10 minutes). Pour over the chilled biscuit base and refrigerate until set.

Step 3- Biscoff Chocolate Topping

Melt white chocolate and stir in Biscoff spread for extra biscoff flavour. Pour over the caramel layer and smooth out. Swirl through some more melted biscoff spread and Sprinkle with crushed Biscoff biscuits. Chill until completely set, then slice into squares.

Tips & Tricks

• Line your tin with baking paper for easy removal and clean slices.
• Don’t overheat the caramel– Stir every minute and remove as soon as thickened.
• Make sure to finely crush your biscoff biscuits. Chunky biscuits may make your base crumble.
• Avoid Overheating Chocolate– Melt chocolate gently to prevent it from seizing.
• Chill Between Layers– Chilling each layer ensures clean slices and prevents mixing.
• Make Ahead– Store in an airtight container in the fridge for up to 1 week. Can be frozen for 2–3 months.

Frequently Asked Questions

Can I use a shortbread base instead?

Yes! If you prefer a traditional millionaire shortbread base, substitute the Biscoff biscuits for shortbread.

Can I use crunchy Biscoff spread?

Absolutely. Crunchy Biscoff adds a nice texture to the caramel if you want a bit more bite.

Can I use other biscuits for the base?

Absolutely! Digestives or graham crackers will work, but Biscoff gives the best caramelised flavour.

Why is my microwave caramel grainy?

Grainy caramel usually happens when the sugar Crystallises during the heating process. In the microwave, this can occur if the mixture is overheated, stirred too much, or if sugar crystals are left on the sides of the bowl. If your caramel turns grainy, don’t worry! You can often fix it by adding a splash of cream or warm water and gently reheating it until smooth again. OR my new favourite equipment can save it! An Immersion blender can bring this caramel back to a smooth caramel.

Storage

This slice can be stored in an airtight container in the fridge for up to 5 days or frozen for up to 2 months.
