Ingredients for Biscoff Rocky Road placed on a bench.

White chocolate – I use white chocolate melts in this Biscoff rocky road recipe. Choose a quality brand as the chocolate flavour is such an important part here.
Coconut oil – optional, but a little coconut oil added to the chocolate helps to prevent the chocolate cracking when cut – see tips.
Biscoff spread – I use the smooth spread rather than the crunchy one as you want a smooth melt with the white chocolate. Biscoff spread is also known as cookie butter in the US.
Mini white marshmallows – usually found in the baking section of the supermarket, however if you cannot find them, you can substitute with regular marshmallows and snip them into pieces using a pair of scissors.
Soft caramels – chopped into small chunks. I used soft Jersey caramels.
Macadamia nuts – optional, roughly chopped.
Biscoff biscuits – roughly chopped.
Extra Biscoff spread – for drizzling over the top.

Equipment Required

I find using the microwave (or Thermomix) is the easiest way to melt the chocolate.

A regular baking tin/slice tray – line this with baking paper.
Large microwave safe bowl and metal spoon.
Chopping board and sharp knife.
Microwave, or stovetop, or Thermomix – to melt the chocolate.

Step 1 – Melt The Chocolate

Line a baking tin or slice tray with baking paper, allowing the baking paper to overhang the edges.

Place the white chocolate, coconut oil and Biscoff spread into a large microwave-safe bowl.

Heat, uncovered, on 50% power, stirring every minute with a metal spoon, for 4-5 minutes or until the chocolate has almost melted.

Remove from the microwave and stir until the mixture is blended and smooth.

Expert Tips

Just a few simple tips to make this the best!

Chocolate – I like to use white chocolate for my Biscoff rocky road recipe. Choose a high quality chocolate for melting (I recommend Cadbury, Lindt or Nestle). The chocolate is the main ingredient in this recipe, so choosing a good one makes all the difference.
Coconut oil – add a little coconut oil to your chocolate when melting it as this will help with cutting into neat slices.
Marshmallows – I chose mini white marshmallows for this recipe, however a combination of pink and white looks special too. If you can’t find mini marshmallows, use scissors to snip regular marshmallows into small pieces.
Nut free – omit the macadamias for a nut free rocky road.
Storing – this white chocolate rocky road can be stored in an airtight container in the fridge for up to 1 week.

FAQs

What is Biscoff spread?

Biscoff spread is basically crushed Biscoff biscuits or Speculoos (spiced Belgium biscuits) made into a paste with a similar consistency to peanut butter or Nutella. It is nut free, vegan free, and made with natural ingredients – no artificial colours or flavours!
In the US it is often referred to as cookie butter.
The delicious flavour is described as caramelised, spicy, malty, and similar to the flavour of gingerbread.

What is the best way to melt chocolate?

Heating chocolate in the microwave in short (30 second) bursts, at half power (50%), and stirring each time, is the best way, so that you can control it, and ensure it heats only enough to produce a nice, smooth result.
See my tips for melting chocolate here.
Alternatively, you can melt chocolate in a Thermomix, or in a bowl over a saucepan of boiling water, but take care not to get any moisture in the bowl as this can cause the chocolate to ‘seize’, resulting in it becoming thick and grainy instead of being smooth and creamy.

Can I replace macadamias with another type of nut?

Absolutely! Peanuts, almonds or even pistachios would also work well in Biscoff rocky road. Or, for a nut-free version, you can simply omit the nuts entirely.
